The throttle meister is the cleanest application available and it works like a charm. It replaces the end caps of your bars and uses an internal mechanism the expand or retract from the throttle/grip end. You wouldn't even know it was there if not for the inconspicuous decal for "lock" and "off" I have solid billet bars and it installed with a minimun amount of modification (had to grind 1/16th of an in off a spacer. The heavy I beleive are longer than the standard and are a bit easier to manipulate with one hand. Takes a bit of time to get used to it cause there is a trendency to let go of the throttle while engageing. Wasn't long before I could engage with no noticeable variation in speed. I got to the point that I would set it with slight friction even in traffic as it releives allot of fatigue on the hand.
It warns not to use in traffic and to get used to it on the open road.
I used my going transcontinental and it was essential. Allowed me to run 10- 14 hours a day ..........pretty much gas and go all day. Happy hands all day..............actually had more pain in my elbows from resting them on the tank for two hours at a pop
The 14 oz Heavy is the only way to go. The stock bar ends weigh 11.5 oz. The standard Throttlemeister weighs 12 oz which results in an even weight swap. The extra 2 oz. of the heavy Throttlemeister reduced handle bar vibrations. Check "AZMotorsports.com" for a great price. Bob
