Atlas Floating Engine sprocket

TopgunPeter · Aug 6, 2024

While working on the primary drive of an Atlas I have just bought I found a strange engine sprocket which appears to be
using a Jawa component as on this link with sprocket that floats:

The sprocket is a flat splined one presumably Jawa.

Does anyone know anything about it ?

I believe alcotrel on here uses the jawa setup on his race bike
Hopefully he'll be able to help

Yes, I have a one like this. It is a quick change unit, usually comes with splined sprockets.
Mine was made by Talon probably 30 years ago. Somewhere on here, I posted pictures of it.
