Typical Renthal quality. The dual compound allows a softer grip to absorb vibration and impacts without being too soft and squirming around under weight and the 3mm oversize allows greater more material to absorb shock and better fit for an average size large hand. I combined these with a set of Heli Bars on my sportbike and the difference was amazing.
Installed on my Buell Firebolt. Love them. Fit Great and feel great. I normally ride this bike with gloves so these are thinner then my usual go-to street bike grips (listed in recommendations) They provide excellent grip and are from renthal, A name I learned to trust the first time I threw a leg over a dirtbike. I did go with a thinner grip knowing my gloves would provide some coushin though I have ridden without gloves and Felt very comfortable doing so.
