The X-GRIP TORQUE DISC is a bolt-on flywheel weight that adds rotating mass to the clutch side, increasing momentum and stabilising engine behaviour in the low rev light 273 g version (SKU XG-2638) is tailored for modern 250–300 cc two-stroke enduro engines from KTM, Husqvarna and GasGas, optimising traction and torque delivery for demanding off-road use.

Key features and benefits

Ideal flywheel mass that significantly reduces RPM drop when the throttle is closed or when the rear wheel encounters high load.
Increases effective torque and makes power delivery more controllable, especially in slow, technical terrain.
Gives the engine a trial-like, tractable character with smoother low-end response and improved grip on loose or slippery surfaces.
Helps reduce engine stalling in steep climbs, rock gardens, roots and tight switchbacks.
Developed for hard enduro riding, where precise throttle modulation and momentum are critical.
Compact disc design mounted on the clutch, keeping overall engine width virtually unchanged.
