This is my second pair of Pro-Taper Synergy grips. I had my first pair on my KTM 525 EXC. Those lasted a little while then tore in the recesses of the diamonds. This pair didn't make it past installation. Upon installing both grips formed small holes in the small recesses of the diamonds squirting grip glue all over...including in my beard. They are very comfortable, but aren't going to hold up since they already have small tears in them. If you feel the need to try these I would at least poke a small hole in the end of each grip to relieve the pressure for installing them.
If you want the very best in grips go with these. i Love them. You will get such great grip with these Dual compounds you will love them, unless you ride without gloves of course. these things are mean on hands with out gloves but with gloves you will get such a good grip you'll never buy another brand.
I tried 3 times to get these things on my handlebars. I used ProTaper glue, they locked up 2/3 of the way on! I had a temper tantrum and refuse to attempt it again. Ordering spiders right now, they went on my other bike easily and felt better anyways.
