All parts for your BMW motorcycle conversion
Our team at Sport-Evolution can look back on over 25 years of accumulated know-how. All spare parts for BMW motorcycles available from us are thus also used for our conversions and in our daily work. So we know exactly what we sell. All BMW motorcycle conversion parts and spare parts, such as rear frames, triple clamps, suspension kits, wiring harnesses, mudguards, etc. we manufacture ourselves. Quality is always our first priority. Since 2017, Sport-Evolution has been verified by TÜV Cologne to be able to manufacture parts with parts certificates for components subject to registration. This means that our BMW motorcycle parts can be registered at any local TÜB without any problems.  

Trust in our experience: also for motorcycle parts for your BMW 
With BMW Motorrad parts from Sport-Evolution you get highest quality and small series productions, which make your machine individual and raise it to a new level. Experience how new parts, such as a new triple clamp, give your old BWM a new riding character. Nevertheless, the classic look is never lost, after all, we take care with all spare parts to remain as true to the original as possible. 

The combination of classic look and modern technology 
With the right motorcycle parts, you can turn even a 25-year-old BMW into a modern, dynamic bike. With a new chassis, even an older BMW two-valve bike becomes a cornering predator that doesn't have to hide from more modern machines. We offer complete conversion sets or, for example, the right fork spring kit or replacement shock absorbers for all BMW classics. In our store you can conveniently order all necessary BMW Motorrad spare parts for your conversion project online.
