Construction:Injection-molded Krayton synthetic rubber

Fitment:Size refers to the outside diameter of the bar end on the left side of your motorcycle. If you dont know the O.D. of your handlebars, measure with a caliper, an open-end wrench or other device. Each set comes with two grips: one for the clutch side (small inside diameter) and one for the throttle (larger I.D.) Installing the wrong grip on either side may result in loose-fitting grips or grips that can tear and stretch too far during installation.
