Moved up from a CBR929 and a 600RR. Never rode any of the CBR1000's before and I still have the 600RR.
The BMW is an amazing machine, you will not be disapointed with this jump. Plus, after 18 years of street riding it was time to move up to a more refined machine like the S1000RR.
Also, I was able to get the traction control/ABS package for free in the deal.
