The CBR 1000 RR celebrates its 20th anniversary in 2012. During those 20 years, the bike transformed from the original CBR900RR, to the CBR929RR in 2000, the CBR954RR in 2003, and finally the CBR1000RR in 2004.
The CBR1000RR hasn't received many upgrades since becoming a 1000cc machine, but that all changed for the 2012 model; the most notable update to the 2012 CBR 1000 RR directly relates to better handling.
Honda says: "Changes to the CBR1000RR for 2012 focus on sharpening what is arguably the most critical component in a motorcycle designed for sporting use: chassis performance. Granted, big-time horsepower always holds its own attractions and the CBR1000RR pours out huge quantities of horsepower and torque right in the midrange."
