Been riding with a twist throttle not for almost a year on my Sportsman 500. I Have always been a avid motorcycle rider and figured I'd like the twist a lot more. When a friend wrecked my rig and broke my thumb throttle, I figured I would change it out.
Things to know.
1. Standing is a little harder to control and work throttle. If you are used to dirt bikes, it’s not a big deal.
2. Make sure your pivot point for your wrist is above the throttle and not below( Just adjust handle bars). When hitting brakes hard a low pivot point can cause you to give it more throttle and this can be a problem. That being said, mainly wanted to change FROM the thumb throttle due to almost wrecking on 3 occasions when I hit a rock that was too big to nicely roll over with the right tire. When I did this, the right wheel ( and handlebar) would come back and my thumb would mash down on the throttle causing some excitement.
3. Responding to accidental twisting and wrecking the machine. All I can say is before you get off the rig, put it in neutral and shut it off!! My lovely wife almost did the same thing and crashed into the fence.:motz: This is not really a problem except we all get used to using the handle bars as support. Just need to retrain the brain!
4. Another pro is no thumb fatigue on long rides! I hated that.
All in all I think control is better and the feel is better. The only downfall I have noticed is climbing hills takes more care.
As a side note, on the 2002 SP 500, I had to put a twist tie in between the two mettle pieces under the cover where the throttle was. If they come in contact while running, the rig will shutoff. I left this part on due to the AWD selector switch being there as I have not looked for a way to change that out yet.
