I had some issues with hand tingling and soreness on a long, multi-day ride a few weeks ago: Aches and Pains After a Long Day - Harley Davidson Community I ordered and installed a "Crampbuster" and went for a 300 mile ride yesterday with them - what can I say, it was simply magnificent in north Georgia Thursday!! So far, I'll give it a grade around a C. I just couldn't find the "sweet spot" as far as the location on the right grip. If I had it high enough to easily rest my hand on for a break, it sort of bugged me during normal throttle operation. Vice versa, if it was low enough to be out of the way for normal riding, it was too low to effectively rest my hand on. There was still improvement over my last long ride so I'm not complaining too much. Hey, it was only $11 bucks. Anyone else try this product and have similar feelings? Is it something I will get used to pretty quickly? I'm also starting to think a large part of the problem might be how hard and firm the stock grips are. Hanging on to those things for 6+ hours a day starts to wear on you. Next step might be to try those spongy/foamy grips or move all the way up to the Kuryakyn ISO Grips - pricey but I loved them on my Sportster. As always, thanks for any input and/or suggestions.
