BMW Motorcycle Restoration - Professional Restoration of Classic BMW Two-Valve Models
A high-quality BMW motorcycle restoration is far more than the repair of individual components. It is the consistent restoration of a motorcycle in technical, optical, and functional terms. The goal is to preserve the character of the vehicle while creating the basis for many more years of riding enjoyment, reliability, and value retention.
Sport-Evolution specializes in the restoration of classic BMW two-valve engines. Whether it's a BMW R80, BMW R90S, BMW R100, BMW R100RS, BMW R100S, BMW R100GS, or other Boxer models - each motorcycle is individually assessed and restored to the highest quality standards.
Systematic Restoration of Classic BMWs
Every BMW restoration begins with the complete disassembly of the vehicle. Engine, transmission, chassis, electrics, braking system, and attachments are carefully inspected, measured, and documented. Only on this basis is an individual restoration concept developed.
Complete disassembly allows for reliable detection of wear, signs of aging, and previous repairs. This way, all technical and optical work can be precisely planned and implemented.
Engine and Transmission Overhaul
The air-cooled Boxer engine forms the heart of every classic BMW. As part of a BMW motorcycle restoration, the engine and transmission are completely disassembled and technically overhauled.
Depending on the condition, the work includes, among other things:
Cylinder head overhaul
Lead-free conversion of cylinder heads
Replacement of valve guides and valve seats
Overhaul of cylinders and pistons
Replacement of bearings, seals, and wear parts
Complete transmission overhaul
Overhaul and tuning of carburetors
The result is reliable technology that meets the demands of a high-quality restored classic.
Chassis, Brakes, and Electrics
In addition to the engine and transmission, the chassis, braking system, and electrics are also comprehensively checked.
Forks, shock absorbers, bearings, and brake components are repaired or replaced. The electrics are checked, overhauled, and designed for reliable operation. This not only improves operational safety but often significantly improves handling as well.
Original or Individual Aesthetics
Every BMW vintage motorcycle restoration naturally also includes the visual refurbishment of the motorcycle.
Frame, swingarm, and attachments are recoated. The paintwork can be done either true to the original factory specifications or according to individual customer wishes. Numerous components can be reconditioned, replaced, or newly refined.
This creates a motorcycle that meets the highest demands both technically and aesthetically.
