Regular handlebar diameter, 7/16" The throttle side is slightly larger to fit the throttle tube. As far as length... i'm not sure, but it is the same length as any other Progrip grip. I have them on my R6, and they work perfectly. The rubber around the end cap needs cut off first, but that's nothing scissors or a razor can't handle in 3 minutes.
