you guys are right 600 or 1000s there all the same really the only difference between them is 1000 is heavier and has more touque. my matee had a suzki gsxr 2003 600 that did a 10.9 and in the broucher they said they do 11.3 lol guys on r1's where like what the f#$k. the r1s where doing 10.5 - 11s.

if you have the coin go an aprillia 250 2stroke same as the rgv motor but the next development. 3 stage power band, tops out around 230 and gets there quicker then an rgv. the guys are right if you are diciplined enough get a four stroke 600 and spend a bit more and get more bang for ya buck. but hey if you love the rgv get it. i loved them 5 yrs ago so i got one .

any more questions ask away ive owned one and a mate owned one with a 50 shot of nitros, great bike and no matter what 2 stroke ya on for the displacment they will allways produce 2 times the power of the four strokes ( just look at the dirt bikes)
