they stop tthe side to side motion through bumps alot, so if you do get one you won't have your hands get bumped off the handlebar, but someone said it stiffens the turning alittle, but is not greatly noticed. They are a good invest ment, but i think Dirtwheels said the Suzuki has too light steering so people would buy a stabilizer right when they get there quad, the stock turning is perfect for racing, if it is too light then my YFZ is worse.
