Norton ISOLASTIC RUBBER - REAR ENGINE MOUNT
Rubber Isolastic rear engine mounting insert for the Isolastic engine-isolation system, PN 061227.
This is a rear engine mounting rubber from the Isolastic system, listed here under part number 061227. It shows up in the parts book under the Engine Mountings, Head Steady, Centre Stand grouping, which is where Norton kept the hardware that isolates the engine, gearbox, and swingarm as a unit from the frame.

The Isolastic setup uses rubber-and-metal mounts like this one to soak up vibration from the engine before it gets to the rider, rather than bolting the powerplant rigidly into the frame. This particular mount sits at the rear engine mounting point in that assembly. Our catalog record for it spans appearances from 1971 to 1973, but it doesn't spell out which specific model years it was fitted to beyond that, so confirm it against your bike before ordering.
Given how central the Isolastic mounts are to how the whole engine cradle sits and moves in the frame, it's worth double-checking fitment details with us if you're not certain this is the exact mount your bike needs.
