Nice addition to the grip.

The Throttle Boss serves its purpose, allowing me to loosen my grip on the throttle while cruising. Easy to mount and of good quality. I bought the pair, but found the left-hand unit got in the way, and didn't really add much.

Great little gizmo, allows the heel of your hand to control throttle so you can loosen your grip on long rides.

I got just the one throttle boss and love it. I didn't realize how nice it was to ride and have a place to relax the outside palm and fingers.

Great little piece to make longer cruises easier on your grip. You'll get used to it being there, even when you don't need it, it won’t be obtrusive...unless you're a pansy. When on a long ride, you'll love its utility.

Throttle Boss

Placed on my 2003 VTX, amazing how much relax it feels specially on longer trips. Abeautiful and useful complement to the ISO grips and overall look for the bike.

Throttle boss is great

If you get the iso grips, get the throttle boss! Great for long trips. It does exactly what it's supposed to do. The only problem that I have run into is I have a handlebar strap that I couldn't slip over it to strap the bike down for transportation. Not sure about durability, I haven't had it long enough... but, it is very well built so I don't see any problems in the future.

Throttle Boss

I've had the ISO grips for a couple of years. While I agree they have plenty of grip already, the Throttle Boss was an exceptional addition. It's really hard to believe how BIG a difference such a small part can make an hour into a long ride. I can't recommend it strongly enough!

Works as advertised

Went on easily, it's there when I need it, unobtrusive when I don't! Great for those long rides. Nice and shiny and blends in perfect with the iso grips. As usual, Motorcycle Superstore got it here quickly.

I installed the black throttle boss with the black ISO grips and am very pleased with all of it. The throttle boss makes cruising a lot nicer since you can relax your hand.

Kuryakyn ISO Throttle Boss

This little gem is a dream. No more stiff throttle fingers on the long rides anymore. Your lower hand rests on the "Boss" taking alot if not most of the pressure away from your fingers while holding the throttle in position.

Excellent product. Size is perfect - large enough to offer easy throttle control without getting in the way of :normal" throttle operations. Quality finish that integrates perfectly with the ISO grips.

Iso Throttle Boss

Very good item to add to your grips. Takes the pressure off your throttle hand and relaxes your wrist. One thing, if you don't get your grips in the correct position the adjustment can put them either too high or too low. I adjusted the tension on the throttle and solved the problem.

I like this thing much more than I expected. Really nice to relax your hand on long rides. There's cheaper versions that do the same thing, but this one looks nicest and integrates perfectly with the ISO grips.

Nice addition to the ISO grips

I bought the grips and love them. Perfect fit on my Suzuki 650 scooter and while the Throttle Boss is really pretty unnecessary, it's a nice addition. The only reason you would want the left Boss would be in case you're anal enough to need both bars to match. The Bosses are a breeze to install but take up a bit of grip space and are a bit to get used to. I'd buy it again unless it broke...built strong and is not junk.
