The Renthal Diamond Road Race Grips are available in 3 different advanced rubber compounds from soft, medium to firm. Each Street Grip offers a different level of tackiness to suit a variety of riding conditions and individual style.
Purchased the medium compound grips for a 2004 CBR600RR. Fit the factory clip-ons with factory end weights without any interference problems. I installed them with an air hose, without using any glue and I don't have any problems with them spinning.
