Thumb Throttle

[BenHonda400ex]

Can someone tell me why people put 400ex throttle on their Four-Wheeler? What makes them so special?

They've got a good leverage ratio, and they are a dime a dozen. Alot of 450r people use them along with the 90ex lever, which is 3/8" longer.

I have one on my Kawie too. Shorter throw and much smoother.
