Not many people retain the transmission, but it all depends. Is it shaft driven with a fixed ratio? Is the transmission separate from the engine? In many cases they're built into the same housing. It's extra weight and volume that can be better used for battery space.
There's performance gains (better acceleration) but not much as far as speeed, as that's limited by HP of the motor.
What kind of motor are you thinking? Range? Top speed? Budget?[/QUOTE
I would like 100 miles range, and want some performance that is on par with stock or better
The transmission unbolts from the engine and has dry clutch setup like a car and I could make an adapter from a clutch disc.
I do not believe the swingarm is part of the transmission. I think I am ok on the frame as well.
would like to use the warp 9 from the truck project, but not going to work, lol
I am thinking lithium, 72 volts 30HP or whatever would be like the 60HP stock.
Budget? we don't need a stinking budget! Seriously, wanted a brammo empulse but not ready to drop that much.
I looked up the transmission and it is 25 pounds, so not a huge weight problem..
