The 600rr are not any faster than an F3, my mate has one and when we both open our bikes up there is little difference. But I must admit they do look the mutts nuts.

 

after 60 i'm sure is where the RR will stretch its legs... the 2007 RR runs the 1/4 with a magazine rider at 10.5 @ 134 where the 600F3 ran it in 11.00 @ 124 thats a big mph difference.

i don't really want an RR, this thing needed a new back tire fairly soon anyways. saves me $250 in tires.

 

crap! the guy backed out but i still have some more offers...i really wanted that yellow F4 i found and its only a block away from me. dude is asking $3600. it has 9500 miles, needs a tuneup.

 

Nothing wrong with the F4 - great bike. It's definitely an upgrade component-wise. I wouldn't consider it, "wasting your money" unless you could find an F4i for under $3500-$4000 (not stunted, either).

 

yeah although havoc filled me in that he thinks that F4 i saw for only $3600 was downed and the guy just put on some junkyard plastics... u can't tell by pics.
