Guide
The BMW R75 rebuild
The classic among conversion bases
With the /5 series, BMW repositioned the boxer engine in 1969: new frame, electric starter, telescopic fork. The R75 was the top model of the series and is still known today for its silky-smooth engine performance. As a base for customization, it impresses with its classic proportions and chrome charm – perfect for a 70s-style café racer.

FAQ
Questions about BMW R75
Can't find your question? Use our parts inquiry form – we will respond personally.
Do R80 and R100 twin-shock parts fit the R75?
A great many. Triple clamps, tail conversion kits, exhaust systems, and brake discs for the twin-shock models from R75 to R100 have been developed together. Our product titles list all compatible models.
Is it worth converting an R75/5?
The /5 is a sought-after classic. Those who value originality tend to restore it. However, it makes a fantastic base for a café racer or roadster – ideally with a reversible conversion, using parts that fit the original mounting points.
Does the engine need to be converted for unleaded fuel?
For older boxer engines, we recommend a cylinder head overhaul with hardened valve seats. This allows the engine to run permanently on unleaded fuel. We offer this service in our workshop.
Can I also get advice for my R75?
Of course. Send us photos and the year of manufacture via the parts inquiry – we will let you know which parts fit.
