Thumb Throttle on a bike?

Most 4 strokes have 2 throttle cables, but 2 strokes have just 1.

There's also this solution:

My dad had his knuckles replaced when arthritis set in and he regained use of his hands for almost 30 years. Modern medical technology is amazing.

I can't hurt to ask your doctor about it.

Friend that got me into bikes always uses a thumb throttle. He raced quads before, so it is what he was used to. I tried his bike one time and it was no big deal, if it helps you enjoy riding, go for it.

Figures......... late to the party. If your running a FCR carb, its a easy swap,but if your gonna do it, make sure you use a Honda 04-05 TRX450R throttle assy. Better ergos with the Honda throttle. You can also angle the thumb throttle were your moreless palm throttling it. I dont even use my thumb with a thumb throttle. I just palm it. As for the comment about the single cable and dual cable setup. Nothing too it. I ran a CRF450 FCR on my Honda TRX450R.
