11 Tooth Driver

Can someone post some quick details on exactly what parts are required for a 11T driver on a bully style clutch? Just want to be sure before ordering.

Does anyone recommend anything smaller than a 11T for junior classes running indoor races......indoors meaning horse show type arenas?

Thanks

The 11t kits from Buller have all you need. I would order spare spacers and snap rings as they have tendency to fly across the shop at the worst time

Its a short season now but they tend to wear out , the teeth and bushing .
Ten tooth requires outboard mounting , most often with a crank extension .
If possible id stay away from that and run bigger rear even if it gets in the dirt some . Chain and gear are easy to replace vs broken crank .

The main thing is the spro-lock style snap ring . The chain rides up on the standard one .

There is a smaller OD outside thrust washer, and spiral lock instead of snap ring used to clear the smaller driver(s.)
If you use the standard outside thrust washer and snap ring -- the chain will ride up on it and cause problems.
9 & 10 T are outboard only with an extension. No problems with crank breakage on lower HP classes -- anything over a stocker though, and I'd avoid using them.
