Motorcycle Flywheels

The Trail Tech Flywheel is a bolt-on solution that replaces the stock flywheel. Installation takes only about 30 minutes and is very simple - no drilling, tapping or grinding required.

* Ever find yourself in the woods, riding through tight, twisty, rocky trails, and the bike is constantly stalling; you're over using your clutch to control the speed, and you're getting worn out?
* 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? It may be your flywheel is unbalanced.
* 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.
* Use an air ratchet for easy removal, and using the correct flywheel puller is required.
* All Trail Tech flywheels are listed by the weight added to stock. Stock weights are indicated in the description.

Adding weight:
Adding weight increases inertia, which reduces the bike's tendency to stall at low speeds. In no way is top speed affected - the heavier flywheel just smooths 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.

Subtracting weight:
Subtracting weight allows the engine to rev faster, which provides a distinct advantage when getting up to full speed quickly is required. Sand, dune and MX riders will generally choose a light weight flywheel. Increases accelleration/snap.
