Rolon Brass Chain & Sprocket Kit for Honda CBR 250R — Kit 331

The drivetrain takes more abuse than almost any other part of the bike — every gear change, every hard launch, every monsoon commute runs through the chain and sprockets. When the stock kit starts stretching or skipping, this is the upgrade that fixes it properly rather than papering over it.

Rolon is made by L.G. Balkrishnan & Bros (LGB), an Indian chain manufacturer with roots going back to 1937 — this isn't an unknown import brand, it's drivetrain hardware from a company that's been making chains for automotive and motorcycle use for decades. This particular kit uses brass-plated inner and outer link plates rather than standard steel, giving genuinely better rust resistance and a distinctive polished look that stays lustrous instead of dulling with age — built with an eye toward stunt and adventure riders who put real load through their drivetrain.

The front sprocket (14T) is precision-machined for smooth, quiet operation and higher transmission accuracy, with anti-wear coating so the bike keeps putting power down cleanly instead of losing it to a worn tooth profile. Every front sprocket goes through 18 production stages and 15 individual quality checks before it ships — heat-treated and hand-finished, not just stamped and packed.

The rear sprocket (38T) is carbon steel with induction-hardened teeth for serious wear resistance, zinc-coated against rust, and shot-blasted for improved surface fatigue strength — built to take dust and mud in stride, not just clean city roads. Both sprockets are machined to OE position accuracy, so the fitment is precise rather than approximate.

In the box: front sprocket, rear sprocket, and a 108-link brass chain — everything needed for a complete drivetrain replacement in one kit.

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 water jet directly on a seal-ring chain), and replace the chain dampers at the same time as the kit for the best lifespan. Professional installation is recommended.
