I rode my friends Rev 600 today. Its got more nut than my sled but I have a 94 Form Z (don't worry i'll have the f5 by next year) ha ha. The only thing I can say I was impressed with was the response from throttle pull but this is only comparing it to my sled. I was dissappointed with the seat even though some think its the best feature. I like to ride right up by the tank with my feet folded back, makes me feel more in control. First turn I took I tipped it. Its too top heavy and skinny. I gotta say I'd have more fun on than my sled just because it goes faster, but its nothing I'd empty my pockets for.
