About tuning the R 18
What suits this motorcycle.
The R 18 is listed in the Boxer Tuning catalogue for Engine Optimisation, Stage 1 and Stage 2. With the largest boxer engine BMW has built in modern times, riders usually want a smoother throttle at town speeds and a stronger pull when the throttle is opened.
What you’ll notice
Changes you can feel on the road.
This is not about filling a page with ECU terminology or promising one universal result. It is about choosing the right route for the motorcycle, its hardware and the way you ride.
Less abruptness around town speeds and when the throttle is first opened.
If the bike has aftermarket hardware, it is assessed together with the software before a route is recommended.
