Keep your Himalayan’s driveline adventure-ready with the Rolon OR 251 O-Ring Chain & Sprocket Kit. Purpose-built for the Himalayan 411, this kit pairs heat-treated steel sprockets (15/38) with a 520 x 110-link O-ring chain that seals lubrication between pin and bush for quieter running, reduced stretch, and longer service intervals. The gearing matches stock, so you maintain factory rideability while improving smoothness and longevity.

Rolon is one of India’s most trusted OEM-grade manufacturers; their Himalayan kit is engineered for off-road dust, slush, and touring miles. Install, set chain slack to spec, and lube regularly for best life. Buy from Under The Hood for guaranteed authenticity, fast pan-India shipping, and hassle-free support.
