- Aluminium SOHC Bottom Bevel Casting, as fitted to all road going Internationals and many racing Internationals as well as some SOHC Manx Nortons. -
As with the magnesium items, these castings are just as per original Norton items, cast in high quality LM25TF heat treated aluminium and fully CNC machined in the UK.
They also include the phosphor bronze bearing with all oil grooving, which after fitting is pinned and honed for the bevel gear, just as per original. As a final touch, these items are polished to a high finish and look really nice when fitted.
