Elevate your off-road game with the ultimate "stump-puller" upgrade. For the 2025+ generation of the KTM 390 Adventure and Enduro, the stock gearing is often a compromise for the highway. This 50-tooth rear sprocket throws that compromise out the window, giving you the low-end torque needed to crawl through rock gardens and loft the front wheel over logs with ease.

Whether you are navigating tight single-track on the 390 Enduro or looking for more control on the 390 Adventure S, this sprocket is the key to unlocking the full potential of the LC4c engine.

Why the 50T is Essential for 2025+ Models

Ultimate Off-Road Control: Shortens your gear ratios to provide better low-speed modulation, reducing the need to constantly feather the clutch in technical sections.
Mountain Goat Climbing: Makes steep, loose inclines feel like flat ground by putting more torque directly to the rear tire.
Factory Grade Durability: This sprocket features a rugged, high-strength steel construction designed to handle mud, grit, and heavy torque loads without breaking a sweat.
Multi-Platform Compatibility: Designed specifically for the newest 390 chassis, ensuring a perfect fit for the Adventure, Enduro, and the street-oriented Adventure S.
