what I like lost about Throtlemister is you don't have to think in a panic situation, all it does is Stiffen the return, so if your resting your hand on the throttle
you just slam off throttle, there's nothing to unlock or do, they look clean and if they didn't say ON OFF on right side people think there just Bar Ends
$145 seems expensive but when I ride its usually 200-400 miles, and it works perfect for when you just want to rest your hand for awhile. Yes it drops a few miles a hour going up hill or over overpasses, but ya know what , the wind is in my face and I just relax, listen to my tunes and Breath !!!! Ride Safe Ride Often !!!!!!!
