i agree, you will most likely get bored of a 600 or smaller, i started out on a 600 and the second i started wanting to ride wheelies i hated it. for one if you a big guy like me , you aint gonna pull up going any faster than 30-40 mph... so your all up in the parking lots learning slow wheelies (alot harder) to start out with.. if i was on a r1 i would be pullen em up on the interstate and shit.. and the faster you going the easyer it is to keep up (like more give, if you will) the slower your going teh more twitchy it is.. but then again, i think learning wheeleis in 1st gear is better, cause your accedents are more like skatebording accedents and not desasters like 80 mph loop on 275 LMFAO
