Mechanical differences between S1000R and RR motors
on: February 24, 2021, 03:41:29 AM
For comparable model years, or as comparable as possible model year ranges, which engine parts differ between the R and RR? I'm sure this has been covered in more than one place but I can't find it with search.

It's pretty much just the cams and valves that differ. After that, it's all down to the ECU tuning, meaning that jus swapping cams and valves won't get you an extra thirty horsepower unless you change the engine management, too.

If you go to this web site for parts. You can pick out part numbers for items you are interested in. Pick out the other bike and see if the numbers are the same. Basics suggest cam lobe timing and computer programing will be the big differences. Might take some hunt and peck but you can look up any part.
