Rolon Brass Chain & Sprocket Kit for KTM Duke 250 (2017–2023) — Kit HXRC 372NF

The Duke 250 sits right in the sweet spot of KTM's naked lineup — enough power to reward a proper drivetrain, not so much that you need to go overboard. The Rolon HXRC 372NF is built specifically for the 2017–2023 Duke 250, giving you genuine OE-matched fitment with brass-plated chain link plates for real corrosion resistance and a finish that suits the bike's aggressive styling.

The front sprocket mounts via a 2-tap PCD with involute spline and bonding for a precise, secure fit, precision-machined for smooth, quiet operation and higher transmission accuracy. The rear sprocket uses a 6-hole pattern, heat-treated and hand-finished rather than mass-stamped, with anti-wear coating that keeps power delivery clean. Every sprocket passes 18 production stages and 15 individual quality checks before it ships.

Important fitment note: this kit is for the 2017–2023 Duke 250 specifically. The newer Gen3 Duke 250 uses a different Rolon kit with a different tooth count (14T/43T rather than this kit's 14T/46T) — confirm which generation your customer has before selling either.

In the box: front sprocket, rear sprocket, and brass-plated chain.

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.
