Off-road motorcycle axles range from 17 mm to 32 mm. Ordinary wrenches are simply too large and heavy to carry with you, so CruzTools developed updated combo wrenches to handle most make and model combinations. One has 22 mm and 27 mm, while the other combines 22 mm and 32 mm. Both include 14 mm for the O. E. M. spark plug sockets. Wrenches are forged - not stamped - for extra strength and sport a polished chrome finish to give your fanny pack a little bling. Size: 14 mm x 22 mm x 27 mm, 14 mm x 22 mm x 32 mm, or 27 mm x 32 mm. Sold individually.
