If you have a small stroker motor and want better ET times than what a stock cut tranny is doing for you and hate spending money on replacing bad gears, shafts and shift forks..
The new billet tranny is the way to go.. With a lower first gear, different ratio's on 3rd,4th and lower 6th gear. You get faster ET times and the billet tranny will last for years to come..
Think about it.. Add up everytime you replace gears or shafts and still run a tranny that is built for moto-x, not drag racing.
Buy a billet tranny that is setup for drag racing and pull faster ET times. Plus never replace gears and shafts..
I love running my 392cc stock stroke Titan Racing Cub with the billet 6 speed tranny. My 60ft times are in 1.20's. In the 1/4 mile 9.90's. In time, those times will be faster yet..
With stock cut 6 speed. 60ft in 1.40's. Best 1/4 mile 10.30's
I'm also running a billet 6 speed in my 710cc 20mm DM.. Pulling 1.10's 60ft times.. Plus pulling some crazy 1/8 and 1/4 mile times too..
