ya ive heard they are awsome but the backs are 12 wide and i only wanted 10 cause ima loose lots of power otherwise. and dose ur brother loose lots of power with them?? cause i have a rincon 680 and im not sure if they will be good or not

 no i talked to them before i orderd and the rubber dosent rip off on trail rideing they are pretty good they are just to big for my quad and they wernt exactly wat i ordered so ya

 Yea you do loose power but you wont notice much of a difference i have a 900 raptor I dontnotice the difference

 i think that will loose traction
