Not knowing your riding style, it's hard to say what's best. In MX you want a good 'snap' in the power band to get you airborn. My stepson rides hare scrambles on his CRf450R all stock, so he looks for big torque surge with power wheelie capability to carry him over the rough stuff while still accelerating. He figures Honda spent a billion dollars getting it right so he put his money in suspension and a Scott's steering damper. Your tires will make a big difference in getting the power to the ground. Closer spacing on the knobbies, like a Dunop 952 will give you more spin at first, then hook up as you get going, so you can just crank it open. S12 Michelins will hook up in the middle of a corner but you have to be careful not to loop out at full throttle so they take more clutch and are good on a short tight track with lots of loose dirt. I run DOT trials tires on my XR400 enduro bike and just power slide it, no clutch, just all throttle.
