Kuryakyn Contoured ISO Throttle Boss

Some things just get better over time, like the Contoured ISO-Throttle Boss for use with Kuryakyn ISO Grips. Updated styling combined with a larger surface area and pad provide even more comfort than the original design while still easing hand and forearm fatigue. The addition of a throttle boss can make the difference between a quick trip and a cross country adventure. They are simple to install and are easily adjustable to suit your needs.

Features:

  • Available in black or chrome finish
  • Right and left-hand side available
  • Sold each

I originally got a cheap plastic cramp-buster that worked for a while, but then I hit it just right and it snapped off. By then I realized, I definitely wanted one of these things. It just makes throttling so much smoother and easier. I put it on when I got the ISO hand-grips, which took a lot of vibration out I didn't even know I was feeling. My ride got a whole lot easier on my hands when I swapped out the stock grips for this stuff. Also of note, I sprained my right wrist pretty good a few weeks ago, so tweaking it just right hurts. But I rode for quite a while yesterday, and never felt anything, largely because I was able to just lean on the throttle using this instead of having to twist using fingers and wrist, etc.

Nice add on to the grip end.
The throttle boss helps to aleviate hand fatigue on long rides typically associated with taller bars and the vibrations that come with them. Good product. I recommend at least trying it out for the minimal cost.

Worked well on my Honda Valkyrie so I figured I'd try them again on my Sporty...

I ride in traffic and can't often use cruise control. This helps switch up hand positions on the throttle.

Love the look, reviews said good things about hand fatigue. I couldn't decide between the regular throttle boss and the Contour, so I ordered one of each. I've seen folks put the regular boss on the left grip just for looks, so I may do that if I like the Contour on throttle side.

Wanted a quality, more permanent wrist rest. Tired of the plastic ones breaking.

I just purchased new Premium Kuryakyn grips for my new Harley. To balance out the bike I ordered the left throttle boss since the premium grips only come with the right throttle boss.

I chose this to help reduce the tension in my throttle hand. I can just lay my hand on the throttle boss and it helps remove the need to twist as much to hold the speed.

Had the Crampbuster for many months. Loved it - however, I lost it on a ride one day. Since I have the ISO grips, I got one of these for each grip (left and right). No worries about falling off now. Easy to adjust and does a great job of relieving the minor cramping that occurs in my hands during longer rides. Plus, they match the ISO grips perfectly. Highly recommed!

I do a lot of 150 mile + rides and was looking for somethign to take some stress off my hands. Already bought the ISO grips through RevZilla so I thought this was worth adding on.
