Steahly Offroad Flywheel Weight for 2017–2023 KTM XC-W, Husqvarna TE 250 & 300 Two Strokes

The Steahly Offroad Flywheel Weight (933) is a highly effective, bolt-on performance upgrade designed to radically improve the tractability of 2017–2023 KTM and Husqvarna 250/300 2-stroke enduro motorcycles. By adding precision-machined rotating mass directly to the engine's crankshaft, this weight fundamentally alters how the engine delivers power to the rear wheel. It smooths out the aggressive, snappy hit typical of 2-stroke engines and translates that energy into manageable, forward-driving traction.

For hard enduro riders and technical trail enthusiasts, a flywheel weight is considered mandatory. The increased inertia allows the engine to "chug" at incredibly low RPMs without stalling out over rock gardens, slick roots, or steep hill climbs. Steahly Offroad manufactures these weights from high-quality steel in the USA, designing them to fit securely over the factory ignition rotor. Available in different ounce increments (handled via variants), you can perfectly tailor the engine's character to your specific riding style and terrain.

Features:

• Smoother Power Delivery: Tames the abrupt 2-stroke powerband, providing a more linear and predictable throttle response.

• Anti-Stall Technology: The added rotating mass keeps the engine spinning at incredibly low RPMs, virtually eliminating frustrating stalls in technical terrain.

• Increased Traction: Smooth power transfer helps the rear tire hook up in loose soil, mud, and slick hardpack instead of spinning wildly.

• Precision Machined: CNC-machined from high-quality steel for perfect balance, ensuring zero engine vibration after installation.

• USA Made: Designed and manufactured entirely in the United States by off-road performance experts.

Fitment Notes:

• Clearance: Installs directly over the stock flywheel under the factory ignition cover. No aftermarket oversized ignition cover is required for this specific application.

   

   

• Installation Criticality: Installing a flywheel weight is not complicated, but following the instructions exactly is paramount. The mating surfaces between the factory flywheel and the Steahly weight must be immaculately clean—use brake cleaner and a clean rag to strip all oil residue. Because this weight spins at up to 9,000 RPM, you must use the specified high-strength Loctite and properly torque the mounting hardware. Failing to secure it correctly can result in the weight backing off and destroying your expensive ignition stator.

Which Weight Do You Need:

• 8oz: Ideal for aggressive woods racers or intermediate riders who want a bit more stall protection while keeping a fast, snappy engine response.
• 10oz: The versatile sweet spot for most intermediate trail riders, offering excellent tractability in varied off-road conditions.
• 12oz: Recommended for casual trail riders, heavy vet riders, or anyone tackling ultra-slow, extreme hard enduro terrain where maximum low-speed lugging is required.
