Engine sprocket (solo)
An engine (crankshaft) sprocket for solo use, listed in the crankshaft and connecting rods section of the parts books, 1960-1962.
E3108/23 is listed in the parts books as an engine sprocket for solo (non-sidecar) use, sitting in with the crankshaft and connecting rods section of the catalog. This is the sprocket that carries drive off the end of the crankshaft to the primary chain, so it lives down inside the primary case, not out where you can see it.

Our records show this number appearing in catalog entries spanning 1960 to 1962, tagged for solo (as opposed to sidecar-geared) applications. Beyond that, we don't have more detail on this one - the entry is brief and doesn't spell out which specific model it was fitted to.
If you're working from an older parts book and came across this number, it's worth calling the shop to confirm it matches what's on your bike before you order, since engine sprockets often differ between solo and sidecar gearing and between years.
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.
