It depends on the type of riding you'll be doing. If you're going to be riding in the city a lot and/or it's a commuter bike, you'll really appreciate the extra torque of the 954. That's one of the biggest reasons I went from a 600RR to a 1000RR -- I hated having the dead spot from 0-6000rpms on the 600.
Thanks for the feedback. I thought the 600 would be better atleast
technologically speaking. I will be doing alot of commuting as I want
it to be a daily rider so now I am thinking 1000rr but how hot do the
underseat exhausts get? Should I maybe just pop for a new 100RR?
