Banshee vs RZ transmission ID'ing

#1 Post by evan_calgary » Sun Nov 05, 2023 9:52 pm

Hi All,

Been a bit. Picked up a bike from Rory so i've been digging through my boxes of parts. Amazing how much you can forget about these bikes in a few yrs.

I've got a transmission sitting in a bag here. Fairly sure its a banshee one from the motor that went in the RS but can't be sure.

What's the best way to determine which version tranny it is? Guessing counting teeth? If so, what's the best way?

If I absolutely have to I can get a RZ trans out of a motor and check but its a bit of a task.

Many thanks!
Evan
