Engine sprocket (sidecar)
An engine sprocket for sidecar-geared outfits, per the factory parts book listing.
E3108/20 is listed in the catalog as an engine sprocket for sidecar use. It shows up in the crankshaft and connecting rods section of the parts books, which is where the factory grouped it, though that doesn't tell us much beyond where the clerks filed the drawing.

The sidecar designation usually points to a lower gearing setup used when a bike was pulling a sidecar outfit, since the extra weight and drag called for a different final drive ratio than a solo machine. Beyond that, our records don't give us tooth count, bore, or which specific engine this sprocket keys onto.
Given how thin the catalog entry is here, call the shop and we'll confirm fitment before you order. We'd want to match this against your actual crank and primary setup rather than guess from the part number alone.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
