Looking for engine sprocket

Can someone tell me where I can get engine sprocket following specs

-13 t
-15mm ID
-WOODRUFF KEY
-219 chain

Thanks

What engine/clutch is this for?

Must be direct drive since he is looking for a keyed sprocket, no? I’ve never seen one keyed

That’s what I’m thinking. But I’ve never come across one that wasn’t either tapered or splined and 11t is generally the largest. The taper can vary too.

Its on a Lightning Rods ebike kit.

Hi

What does

tapered or splined

Mean ?

tapered = a conical shape
splined = grooves cut

Probably not a whole lot of e-bike knowledge on this forum since it is intended for racing go karts.

I spent some time sleuthing for this but no luck so far as I had a need for something like this in 428. 428 and 219 seem to be rareish outside of karting… Although 428 is used on motorcycles too.

It’s an interesting kit, looks like a 219 setup right down to a kart sprocket carrier

Yep
Thats the kit i have.

Has 219 large sprocket that is easy to source.

I can not find these driver sprockets anywhere.
