hey, this will sound dumb, but hear me out.
i have just got a raptor, and my friends are wanting a 350 raptor, i know that i will leave them behind [ not jus cos av gt 310cc more but because i am a lot better rider] but how bigof a performance difference is there between the two quads? and are the 350's any goog at rapin acceleration for jumps because my raptor is. cheerz for any replies.

 

my friend has a raptor 350, and i have the 660. i havent road them back-to-back, but the Raptor 350 accelerates harder then you would expect. I have only road the Raptor on flat grass, and havent got out of 3ed, do to space, but it does pull!!! im sure when you start putting strain on the engine, like running in sand and hill's, thats when the raptor 660R will really shine. Also, you have to shift alot more on the raptor 350 to keep it in the meat of the powerband so to speak. Also, the raptor 350 is noticable narrower, but not as high off the ground compared to the 660R. hope this helps! Happy trails.
