Rolon Chain & Sprocket Kit for KTM 390 Adventure — Kit HXR 337

The 390 Adventure asks a lot of its drivetrain — highway stretches, broken roads, and everything in between — and this kit is built to handle it. The Rolon HXR 337 gives you genuine OE-matched fitment with rubber-bonded construction for a quieter, smoother ride than a worn stock chain.

The front sprocket is precision-machined for smooth, quiet operation and higher transmission accuracy, anti-wear coated to keep power delivery clean. The rear sprocket is carbon steel with induction-hardened teeth for genuine wear resistance, shot-blasted for improved surface fatigue strength, and finished for real protection against dust and muddy conditions — exactly what an adventure bike's drivetrain needs to handle. Every sprocket is heat-treated and hand-finished, passing 18 production stages and 15 individual quality checks before it ships.

In the box: front sprocket, rear sprocket, and chain (114 links, 6-hole).

Keeping it running well: lubricate every 500km for seal-ring chains (1000km for standard), clean every 2500–3000km with a nylon brush — never a steel wire brush or high-pressure jet directly on a seal-ring chain — and maintain at least 1 inch of chain slack. Replace chain dampers at the same time as the kit. Professional installation recommended.
