New Protaper donuts for grips available now. 2 different styles that fit on to grips on Ridstar Q20.
7/8" handlebars. This goes for motorcycles, scooters/mopeds, pit bikes, dirt bikes, ect.
There are some special cases where OEM bars are smaller than the standard 7/8" specifically stock CRF50/TTR50 handlebars and some scooters so double check your bars if you are unsure.
