Off-road motorcycle axles range from 17mm to 32mm. Ordinary wrenches are simply too large and heavy to carry with you, so we developed updated combo wrenches to handle most make and model combinations. One has 22mm and 27mm, while the other combines 22mm and 32mm. Both include 14mm for the OEM spark plug sockets. Wrenches are high strength and sport a polished chrome finish to give your fanny pack a little bling.
