If you have a pair of ISO grips on your Thunderbird then I would check the tab where the pull cable connects to the throttle. This tab broke on me while riding and I was lucky I had just left the I-10 freeway surrounded by semi rigs. Kuryakyn replaced the throttle side grip for me but I won't have these on my bike. If you look at the difference between stock and the ISO the stock grip is much beefier at the point of attachment. Do yourself a favor and check to see if yours is starting to break. Mine gave no sign of failure till it actually broke.

Thanks for the heads up. I've been wanting to add a set of these to my Rocket Touring.

Amazing that companies are so inconsiderate and money hungry they will make such a simple thing cheap enough to risk lives to save a penny in manufacturing. I would email kury and tell them you're done with thier products and link them to this post. I won't buy from them anymore because the pegs i bought from them were garbage, weren't even usable as described, the chrome was horrific, and the rubber got hard and cracked badly after no time. One of the worse products of any kind i ever bought. Now this....i'm definitely done with them.

I did make contact with them and my point to them was safety. I got the impression in my conversation that they know there is a problem but for them to admit that there is a safety issue could be a major lawsuit/recall issue for them. My Thunderbird only has 1200 miles and the grips had been on maybe 500 miles total. They warranty these for one year and were purchased 8/11. Technically they did not have to replace the grip but after explaining my point about the low mileage they reluctantly replaced it. The new throtttle grip arrived and the plastic wrap it came in said it was made in Korea, part# 6236. I agree that for $75-$80 these should be of much better quality. I know these also fit some Honda models and maybe they work fine on some bikes but after this issue I just can't recommend these grips on the Thunderbird. My post is not to bash Kuryakyn but to make riders aware of a potential problem.

It should be ! Not going after them in the most rabid fashion possible is why we get quality like this in the first place. Thats why i said what i did. They have no reason to improve if thier products keep selling and the backlash isn't great enough to hurt them. We are neck deep in garbage products today and they reason is they CAN. So i do not handle issues like this with kid gloves, and trust me, it's I that am on your side, not them. The fact they as you said reluctantly replaced it to me speaks volumes.

Fine! Kuryakyn SUCKS! are you happy now? I've had one issue with one of their parts. I thought posting it in this forum WAS a good way of getting the word out. I did talk with their customer service people. I told them what I thought about the quality and it being a safety issue. What else would you suggest?

I have to say i think that must be a fairly rare occurance. I've never heard of it on any forum. I've had those grips on my Dyna for nearly ten years and never had any kind of problem.
Its distressing, glad you reported it, but my guess is its an isolated incident.

Don't take offense to this, but are you sure you didn't damage the throttle during installation? Or perhaps it's an isolated incident..?

I had the ISO grips with throttle boss on my 2011 Speedy for a year and they were great. I also had the dually pegs (rider) and small ISO pegs (passenger).. and had no issues at all.

I traded the speedy for a Tbird a few months ago and intend on putting some Kuryakyn floor boards on it.

You don't wanna know.
