ROTOR ADAPTOR SLEEVE CUB - Replaces EW ADP-200
Steel rotor adaptor sleeve for the Triumph Cub crankshaft, part 70-4454, also known as E4454 or EW ADP-200.
This is the rotor adaptor sleeve for the Triumph Cub, listed as 70-4454 and also cross-referenced against the older EW ADP-200 designation. It's a sleeve that fits onto the crankshaft to allow the alternator rotor to be mounted correctly, and it's made of steel.

If your parts book shows E4454 or ADP-200 instead of the current number, you're looking at the same physical piece under an earlier designation. As always with small adaptor and sleeve pieces, it's worth double checking your parts book listing against what you're pulling off the bike before you order, since Cub crankshaft and rotor fitments changed over the model run.
We don't have a lot of extra background on this one beyond what's in the catalog, so if you're unsure whether this is the sleeve you need, give the shop a call and we'll help sort it out before you buy.
