25360 COMPLETE ENGINE GASKET SET 650SS 114870 ONWARDS

Norton 650SS Complete Engine Gasket Set – Engine No. 114870 Onwards (Part 25360)

If you’re rebuilding a Norton 650SS and you want it done right, this is the kit. The Norton 650SS complete engine gasket set — part number 25360 — covers all 650SS engines from engine number 114870 onwards. That covers the later production 650SS bikes from the mid-1960s, and it gives you every gasket you need for a complete engine rebuild without cobbling together parts from multiple suppliers.

The Norton 650SS is one of the great sporting twins of the British motorcycle era. With its twin-carb setup, hotter cam profile, and close-ratio gearbox option, the 650SS was built to go — and when you’re bringing one back to life, the last thing you want is a gasket that lets you down after all that work. This set uses correct-specification materials throughout, giving you sealing surfaces that match what Norton originally intended and hold up to real-world use.

Whether you’re doing a full stripdown or a targeted top-end refresh, having a complete set on hand means you never have to stop and wait for a missing piece. Open the kit, do the job, and get the bike back on the road where it belongs.
