H.T. Cable c/w coil sleeve

It shows up in the electrical components section of the parts books, which is where you'd expect a coil lead to live. The catalog record we have doesn't spell out which specific model or engine it was fitted to beyond that general grouping, so if you're matching this against an existing bike, best to compare the old cable and sleeve side by side before ordering.

If your coil lead has gone brittle, cracked, or the sleeve has perished, that's usually when arcing and hard starting show up. Worth checking the whole ignition lead assembly at the same time you're sorting out points or coil issues.
