• Ever find yourself in the woods, riding through tight, twisty, rocky trails, and the quad is constantly stalling; you're over using your clutch to control the speed, and you're getting worn out?


• Ever find yourself riding in the dunes and wishing for just a little more throttle response?


• Something extra to put your quad in front in a sand drag? Ever find yourself on a MX track wanting more snap as you come out of a corner?


• Have you got some vibration in your motor?


• Flywheel balance All Trail Tech flywheels have high strength magnets which boost the stator output by 30-50%.


• Trail Tech Flywheels are CNC machined out of hardened chromoly steel, then balanced.


• Installation takes only about 30 minutes and is very simple - no drilling, tapping or grinding required.


• We do recommend using an air ratchet for easy removal, and using the correct puller is definitely the way to go. Adding weight:

Adding weight increases inertia, which reduces the quad's tendency to stall at low speeds. In no way is top speed affected - the heavier flywheel just smoothes out power delivery The machine will hook up better in soft terrain, and pull stronger. Riding with a heavier flywheel will reduce arm pump and prolong the onset of fatigue. A balanced flywheel will reduce vibration.

Removing weight: Removing weight decreases inertia, which increases throttle response - more snap! Sand sucks power away from a quad, increasing throttle response is a good thing. A balanced flywheel will reduce vibration.

 The stock YFZ450 flywheel weighs 30 ounces. All Trail Tech aftermarket flywheels are listed by the weight that is added to stock: 4 ounce flywheel has a complete weight of 34 ounces (30 oz + 4 oz).
