11 Driver with needle bearing for Bully

I think it would take a custom clutch hub and really small needle bearings to make it fit.

I know the 11t sprocket requires a lot of maintenance - we use lithium grease and clean it often (sometime after the 1st heat) and re-grease the sprocket. Fortunately, we've not had wear issues on the sprocket or hub.
 
None that I have seen. I don’t even think a bushed option would work. I put a light coat of dry lube on mine and pull and clean if it’s real dusty that day.
 
The way I understand it, is that it did happen, but was not successful and there are some out there.
 
Never seen a normal 11 with needle bearings.. simple not enough room.. Now going external (Arena Style) extended beyond crankshaft end are available.

If we have to run 11t drivers - they get cleaned after practice / heat races. Like OvalTech mentioned, dry lube is a good option.
