A well-equipped set will feature sockets in ¼-, 3/8- and ½-inch drive sizes. The ¼-inch sockets fit small fasteners and reach into tight areas best, but are limited in size and the torque they can handle. The 3/8-inch drive sockets are a little larger and able to handle bigger loads, but are still compact and light. Half-inch drive sockets are heavy enough to handle the largest jobs on most motorcycles. Ideally, you will have these sockets in regular and deep versions. If you’re just getting started, the best choice is a six-point socket set: With the socket embracing each flat on a fastener completely, you’ll have less chance of rounding off the corners. If you have a more comprehensive toolbox you’ll want some 12-point sockets, which make grasping fasteners with limited access easier. Plus some motorcycles are equipped with 12-point fasteners—the brake-line banjo bolts on Harley-Davidsons, for example. Speaking of Harleys, you’ll need to know whether the bike you’ll be working on uses metric or standard sizes. Almost all are metric nowadays, but there are exceptions.
