Trail Tech flywheels are complete replacements of the OEM part. Each flywheel is carefully machined from hardened chromoly steel and balanced for a smooth running engine.
Adding weight to the flywheel provides smoother power and more traction in rough terrain. Woods, trail and dirt track riders will generally choose a heavy flywheel. Will allow the rider to ride longer with less fatique and reduce stalling at low RPM's.
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.
Flywheel puller and side case gasket not included with flywheel kits.
