Seems cheaply made. You can't put a ratchet on it. It gets the plugs out of a KTM, so i can't complain too much.
The vast majority of Powersport vehicles require a 5/8" (16 mm) spark plug socket, including Harley-Davidsons, BMWs, four-stroke dirt bikes, ATVs, sport bikes, plus many cruisers and touring bikes. Some require a thin-wall and specific length to fit into the head. CruzTOOLS has addressed the problem with plug sockets in two lengths - 4" and 5" - to handle most applications. Each has a thin-wall hex and an internal rubber grommet to hold the plug in place.
