guys I have a 400x with stock front and rear tires, 450r shocks and ccp steering damper. I’ve been hitting the mx track every weekend and considering a race, would a set of smaller 20" fronts and 18" rears provide a noticeable (worth it?) handling improvement? If so in what ways? I realize the smaller rears will spin up quicker, much like a larger rear sprocket, but will they help corner speed too? I’m trying to decide what will provide a bigger effect on lap times, tires or pipe and jetting. Obviously seat time, which I’m working on. Thanks.
