I had twist on mine when I got it. I got rid of it. I wrecked pretty bad because of it. I also found that I needed riding boots that trip as a result of the wreck. I was coming around a pretty hard left turn, full lateral slide, accelerating, I was last in the pack, following everyones lines, blind turn, come around a sharper part and BAM left wheel hit a rock. Yanked my handlebars out of my hands. As it yanked them my hand blipped the twist throttle. Blaster lifted front tires off and wheelied out of control, accelerating up the side of the hill (we were in a little canyon with a graded hill on both sides) and almost threw me off. My right foot went down (89s dont have heel guards) and under my wheel.
Im pretty sure it broke my foot, it also made my big toenail fall off. This was months ago. My foot is just barely feeling normal by now.
Anyway. After that accident, first thing I did was pawn that thing off to the first guy who wanted to pay me shipping on it. Bought a thumb throttle and a vitos tors delete cable for it.
Never looked back.
Dirtbikes are good with twist throttles. You dont really steer too much with the handlebars, you lean. It doesnt affect the dynamics much. Quads require way too much leaning and turning to make twist throttles work properly IMO.
I just dont like them on a quad. I think theyre dangerous.
