Passion, engineering and true craftsmanship

Sport-Evolution is one of Germany's leading motorcycle manufacturers. Our roots are in professional motorsport: over 20 years of racing, numerous race victories, and several championship titles have shaped our working methods. The experience gained from this now flows into the development, design, and production of high-quality motorcycle conversions, exclusive custom bikes, and innovative conversion parts.
For many years, our workshop has been creating individual motorcycle concepts with a clear philosophy: motorcycles with character, timeless design, modern handling, and uncompromising quality. Each project combines artisanal perfection, technical expertise, and a passion for exceptional motorcycles.
What makes Sport-Evolution special is its exceptionally high vertical integration. From engine machining to chassis development and welding technology, all the way to CAD design, CNC manufacturing, and dynamometer tuning, numerous work steps are carried out directly in-house. This way, we combine traditional craftsmanship with modern engineering to create motorcycles and motorcycle parts that meet the highest demands in terms of quality, function, and durability.
Our team combines decades of experience in classic motorcycle manufacturing with state-of-the-art technology, profound engineering knowledge, and a genuine passion for individual motorcycles.

Exclusive modifications and in-house developments

In the Sport-Evolution manufactory, individual BMW Cafe Racers, BMW Scramblers, BMW Roadsters, BMW Bobbers and BMW Enduro conversions are created based on classic BMW motorcycles. Our focus is on the legendary BMW 2-valve boxers as well as the three and four-cylinder K-models. Each motorcycle is rebuilt from the ground up, comprehensively technically revised and manufactured with the utmost care. Engine and transmission are completely overhauled and delivered with 0 km mileage - our concept bikes leave the manufactory practically as new motorcycles.
In addition to manufacturing exclusive custom bikes, we develop and produce numerous components ourselves. Chassis solutions, engine parts, conversion components and special technical solutions are created directly at Sport-Evolution. Thanks to our many years of experience in BMW motorcycle construction, we know every detail of the vehicles - from engine, electrics and chassis to individual frame and custom-made products.
All motorcycles are built with German TÜV approval and meet the highest demands for quality, safety and everyday usability. Our goal is to bring classic BMW motorcycles to a new level with modern technology, improved handling and high-quality components.

Our Philosophy

What drives us is a passion for motorcycles and the enthusiasm to transform ideas into unique products. From the initial sketch to design and development, right through to the finished motorcycle, we accompany every step ourselves. This very combination of creativity, engineering, and craftsmanship is what defines Sport-Evolution.
Our individual motorcycle conversions and in-house developments are not created for the showroom, but for people who value a true riding experience, technical perfection, and distinctive design. Every motorcycle is based on many years of experience in motorcycle manufacturing, sound engineering, and the aspiration to perfectly balance riding dynamics, reliability, and emotion.
This philosophy is embraced by our entire team. Together, we develop, design, and manufacture high-quality motorcycles and conversion parts that we stand behind 100 percent. Because we don't just build products – we create motorcycles with character that reflect our passion for technology, quality, and motorcycling in every detail.

Engine building for BMW 2-valve boxers - Experience from motorsport and development

Engine construction has been one of Sport-Evolution's core competencies for over 30 years. Our fully equipped engine workshop combines many years of experience in engine repair, cylinder head machining, and performance development of classic motorcycle engines. Before specializing in BMW 2-valve engines, our focus was on the construction, optimization, and support of racing engines and racing motorcycles. Numerous race victories and championship titles are based on Sport-Evolution's technical expertise, development work, and motorsport commitment.
This experience is now directly incorporated into the further development of the legendary BMW two-valve boxer engines. We combine proven concepts from classic BMW specialists with modern engineering, current materials, and innovative manufacturing methods. The result is numerous in-house developments and technical solutions specifically designed for BMW 2-valve engines - from valves, pistons, and ignition systems to extensive engine and performance kits.
We pay particular attention to optimizing combustion chamber geometry, valve seat contours, port design, compression ratios, and squish zones. All developments are tested and verified on our in-house dynamometer. The resulting concepts have proven themselves in many road and sports engines and ensure more power, torque, rideability, and durability.
Whether it's an engine overhaul, gearbox refurbishment, cylinder head repair, or the development of a custom high-performance engine - Sport-Evolution is your competent partner for BMW 2-valve engines. From durable torque engines for the road to powerful sport boxers, we realize engine concepts that are precisely tailored to your requirements.

Suspension service, fork overhaul, and suspension tuning

Precisely tuned suspension is the foundation for riding pleasure, safety, and confident handling. That's why Sport-Evolution offers comprehensive services for suspension maintenance, fork revision, and suspension tuning for the motorcycle brands and models we service.
We professionally restore and overhaul motorcycle forks or rebuild them from scratch. One of our specialties is the shortening of forks and fork tubes. This proven measure improves the weight distribution to the front wheel for many classic motorcycles, provides more riding stability, and simultaneously gives the motorcycle a sportier look.
Furthermore, we have been developing our own suspension solutions for classic BMW motorcycles for many years. With the Sport-Evolution fork damping system, the inner workings of a BMW 2-valve fork can be brought up to the technical standard of modern motorcycle suspensions. The result is significantly improved responsiveness, more riding precision, higher stability, and noticeably more confidence in every riding situation.
Whether it's fork service, suspension overhaul, fork shortening, or the complete optimization of a suspension system – we develop the right solution for every motorcycle and ensure that classic motorcycles provide a modern riding experience on the road.

Performance test bench, tuning, and engine development

For over 25 years, performance measurements and tuning have been core competencies of Sport-Evolution. For us, a modern dynamometer is the indispensable basis for any professional engine development. Only in this way can performance increases be objectively measured, technical changes evaluated, and results reliably documented. Performance and torque data should be based on verifiable measurements - not on estimates or theoretical calculations.
Our Dynojet 250i dynamometer not only serves for performance analysis but primarily for the precise tuning of engines. Thanks to the integrated load control, real driving and acceleration situations can be simulated. In combination with state-of-the-art lambda technology, we obtain exact measurement data to optimally tune injection maps, precisely set carburetor jetting, and optimize engines regarding power, torque, drivability, and reliability.
The insights gained from the dynamometer directly flow into our development work. Whether BMW 2-valve, BMW K-models, Triumph Modern Classics, or individual special projects - every tuning is based on measurable data and years of experience in motorsport, engine construction, and vehicle development.
Our TÜV-approved Dynojet 250i dynamometer is also used for technical verifications and special registrations. These include, among other things, modified exhaust systems, carburetor conversions, performance enhancements, and individual engine concepts. This results in technically mature solutions with verifiable results and the necessary basis for a successful TÜV inspection.

Large parts warehouse for BMW 2-valve models and motorcycle conversions

Sport-Evolution stocks thousands of products for classic BMW motorcycles and custom motorcycle conversions in Neuwied. Our goal is to have almost all conversion, wear, and spare parts for BMW 2-valve engines offered in our online shop readily available, so that orders can be processed quickly and shipped within a few business days.
We place great emphasis on quality and practical experience. Every product in our range is carefully selected and often used in our own custom builds, customer vehicles, and Sport-Evolution Concept Bikes. This means we know the parts we offer not just from catalogs, but from daily use in our workshop, development, and vehicle construction. Product photos, technical information, and article descriptions are also created in-house and are based on our own experience.
To offer our customers high delivery capability and reliable availability, we have invested in modern warehouse logistics and merchandise management systems. Our warehouse is designed for efficiency, short processing times, and future growth. This allows us to continuously expand our product range and get closer to our goal of providing one of the most comprehensive selections for BMW 2-valve engines, BMW K-models, and high-quality motorcycle conversions.

Sport-Evolution Online - More than a Motorcycle Online Shop

The Sport-Evolution online shop combines high-quality motorcycle parts, technical expertise, and personal advice in one place. In our product range, you will find the same components that we use daily in our own custom builds, customer vehicles, and Sport-Evolution Concept Bikes. All offered services, such as engine construction, dyno tuning, chassis service, or metalworking, are also carried out directly by our own team in our workshop.
Our ambition goes far beyond traditional online retail. We don't want to win customers with the lowest price, but with expertise, quality, and personal service. That's why we combine the advantages of a modern online shop with the experience of a specialized motorcycle workshop. Our customers benefit from direct contact with experienced technicians who provide support daily by phone or email with technical questions, custom build projects, or the selection of suitable components.
Furthermore, we see our website as a knowledge platform for motorcyclists and DIY enthusiasts. Much technical information, instructions, background reports, and product experiences come directly from our daily workshop practice and help our customers in planning and realizing their own projects. This creates real added value that goes far beyond simply purchasing a product.
Thanks to a high stock level and modern logistics, we ship motorcycle parts and accessories daily to customers at home and abroad. Our goal is to deliver most orders within two to three working days. At the same time, we continuously develop our product descriptions and technical information. Experience from the workshop is incorporated, as is feedback from our customers. This facilitates product selection, assists with installation, and creates the best possible basis for successful TÜV registration and a smooth custom build.

Product Development and Prototyping

Innovative products don't happen by chance. That's why Sport-Evolution develops new conversion and motorcycle components entirely in-house – from the initial idea to the production-ready product. Our many years of experience in motorcycle construction, motorsport, and engineering form the basis for technical solutions that not only look good but also impress in terms of function, quality, and everyday usability.
For design and development, we use modern CAD systems such as Autodesk Inventor and SpaceClaim. For prototyping, we have 3D printing processes, CNC milling and turning technology, and a fully equipped metal workshop. This allows development steps to be implemented, tested, and optimized quickly.
The development process usually begins directly on the vehicle. An idea first leads to an initial prototype, which checks function, installation situation, and technical feasibility. This is followed by CAD design with detailed 3D models, technical drawings, and the selection of suitable materials. Additionally, strength, manufacturability, and economic viability are evaluated to ensure that a product meets Sport-Evolution's high standards.
After development, another prototype is created that is very close to the later production product. This is again tested on the vehicle and subjected to extensive practical and driving tests. Only when function, quality, durability, and ease of assembly meet our requirements is it released for series production. Subsequently, technical documentation, installation instructions, and – if required – TÜV parts certificates are created.
This consistent development process results in high-quality motorcycle parts and innovative conversion components that prove their worth daily on our own vehicles, customer conversions, and Sport-Evolution Concept Bikes.

3D Printing and Modern Manufacturing Technologies

3D printing has been one of the important tools in Sport-Evolution's product development for many years. We gained our first experience with additive manufacturing as early as 2015. At that time, the technology primarily served to quickly produce newly developed components as samples and to be able to assess constructions directly on the vehicle.
Today, with the Formlabs 3L, we use a state-of-the-art stereolithography (SLA) system that can produce components with exceptional precision and surface quality. The high dimensional accuracy enables us to precisely check fits already in the development phase and to bring new products to series production much faster.
At Sport-Evolution, 3D printing is no longer exclusively used for prototypes. Numerous components are manufactured directly as end products and are used daily on our motorcycles. These include speedometer housings, switch housings, rubber components, control elements, and many other special parts for individual motorcycle conversions. The wide variety of materials offers almost unlimited possibilities – from flexible and rubber-like materials to high-strength technical plastics, to temperature and fuel-resistant materials for demanding applications.
Manufacturing is carried out by precise laser curing of liquid resins, which allows even complex geometries and delicate components to be produced with the highest accuracy. This technology has become indispensable for the development of new products. For example, prototypes for chassis components, housings, fairing parts, or complete footrest systems are created, which can be tested and optimized directly on the vehicle before later series production.
Through the combination of modern 3D printing, CAD construction, CNC manufacturing, and practical testing on the motorcycle, Sport-Evolution accelerates the entire development process and creates innovative motorcycle parts that meet the highest demands for function, quality, and accuracy of fit.

3D Scanning and Reverse Engineering

With the investment in modern 3D scanning technology, Sport-Evolution has taken another important step towards digital product development and precise manufacturing. The high-resolution 3D laser scanner perfectly complements our CAD design, prototyping, and manufacturing, opening up new possibilities for the development of high-quality motorcycle parts and conversion components.
One of the most important applications is the digital acquisition of complete vehicle and frame structures. By precisely scanning frames, engines, or add-on parts, all mounting points and geometries can be accurately measured and converted into digital 3D models. This allows components such as footrest systems, brake caliper adapters, engine protection bars, exhaust systems, or fairing components to be developed and manufactured with the highest precision.
Another core competence is so-called reverse engineering. This involves digitizing existing components or handcrafted prototypes and converting them into complete CAD data sets. For example, exhaust systems, brackets, or special components made directly on the vehicle can be captured, constructively optimized, and then reproducibly manufactured. This process significantly shortens development times and enables the economical production of high-quality small series.
3D scanning technology also plays an important role in quality control. Free-form surfaces, welded assemblies, CNC components, and complex geometries can be precisely measured and compared with the original CAD data. This allows dimensional accuracy, fit, and manufacturing quality to be reliably checked and documented.
The combination of 3D scanning, reverse engineering, CAD design, 3D printing, and CNC manufacturing enables Sport-Evolution to develop new products faster, optimize existing components, and manufacture high-quality motorcycle parts with the highest precision.

Production and Manufacturing at Sport-Evolution

After the development of a new product, the next decisive step at Sport-Evolution begins: manufacturing. Our aim is to carry out as many production steps as possible ourselves, thereby ensuring the highest quality, maximum flexibility, and seamless control over the entire manufacturing process. For this reason, we have an exceptionally high level of vertical integration and extensive technical equipment directly in our factory.
Our machinery includes CNC milling and turning technology, modern welding workstations, tube bending technology, blasting systems, honing machines, valve seat machining, metal processing, and numerous other special machines for motorcycle and engine construction. This enables us to produce and process many components, assemblies, and custom-made items in-house.
In particular, welded constructions such as rear frames, license plate holders, mounting systems, seat constructions, or exhaust systems are manufactured entirely in our factory. This way, we can ensure the highest demands for fit, stability, and workmanship. The close connection between development, manufacturing, and assembly also enables us to quickly optimize new products and continuously develop them further.
For larger quantities or special manufacturing processes, we collaborate with selected partner companies. These include, for example, CNC series production or laser-cut sheet metal parts. We deliberately focus on working with experienced manufacturing companies from Germany, and preferably from our region. Personal contact, reliability, and a shared understanding of quality are more important to us than searching for the lowest price.
Many externally manufactured components then undergo further processing steps in our factory. Deburring, vibratory finishing, surface treatment, quality control, or final assembly often take place directly at Sport-Evolution. This ensures that every product meets our high standards for function, quality, and durability.
Because high-quality motorcycle parts, individual conversion components, and exclusive custom bike projects are not created by chance. They are created through experience, precision, passion, and the commitment to deliver uncompromising quality.

Sport-Evolution - Motorcycle Manufactory, Development Centre and Specialist Workshop

Sport-Evolution is far more than a manufacturer of exclusive concept bikes and high-quality conversion components. We are a motorcycle manufactory, a development company and a specialist workshop for demanding motorcycle projects. For many years, we have combined our experience from motorsport, engine construction, chassis technology and product development with a genuine passion for classic motorcycles and individual customisations.

Our focus is on high-quality motorcycle customisations, technical optimisations and the development of innovative solutions for classic BMW motorcycles and selected Triumph models. We support our customers from the initial idea to the finished motorcycle. Whether it's a complete rebuild, individual custom bike conversion, partial conversion or the completion of a started project - at Sport-Evolution, motorcycles are created with character, modern handling and uncompromising quality.

In addition to vehicle construction, we offer a wide range of specialised workshop services. Engine overhauls, gearbox revisions, cylinder head machining, performance enhancements, carburettor tuning, dynamometer work, chassis optimisations as well as fork and shock absorber service are just as much part of our service portfolio as the development of individual technical solutions. We draw on over 30 years of experience in engine construction and the latest development and manufacturing technologies.

What makes Sport-Evolution special is the exceptionally high vertical integration. Development, CAD design, prototyping, 3D scanning, 3D printing, metalworking, engine construction, chassis development and assembly are largely carried out directly in our own manufactory. This results in products and vehicles that are technically sophisticated, tried and tested in practice and harmonised down to the smallest detail.

Classic inspections or pure tyre services, on the other hand, are not the focus of our work. Our employees, tools and operating facilities are consistently geared towards demanding conversions, restorations, engine construction and custom-made products. This is precisely where our passion and our strength lie.

We specialise in BMW 2-valve models from 1970 to 1995, BMW K models from the K75 to the K1100, as well as Triumph Bonneville, Thruxton and Scrambler models from the 790 cm³ and 865 cm³ series. In addition, we also look after selected motorcycles from other manufacturers on request.

If you are looking for a partner who not only sells parts or repairs motorcycles, but develops, builds and understands motorcycles, then Sport-Evolution is the right place for you. We combine traditional craftsmanship with modern engineering and create motorcycles that inspire - on the road, on journeys and in the garage.
