Motion pro throttle to replace the ride by wire from the factory? Maybe I misread that, unless the early gen1 bikes didn't have that?
It's a quick throttle, reduces the amount of twist needed to get to full throttle. Saved my wrist from carpel tunnel for sure! Don't think ride by wire is affected, others may know for sure. It's a great upgrade in my opinion. Here's a post that gives a few more details: https://www.s1000rrforum.com/threads/motion-pro-revolver-2-throttle-kit.106130/#post-1009154
