Motorcycle chassis fasteners are sized per machine and the socket has to match exactly. A swingarm locknut takes a four-pin socket rather than a hex, and the pin spacing changes with the size, so a 42mm socket will not engage a 43mm nut even though the numbers look close.
The sizes held here are 30mm, 42mm, 43mm, 48.5mm and 50mm, all on 1/2 inch square drive so they run on a standard bar or torque wrench. The size is read off the machine or the manual rather than measured across the nut, because the pin circle is what matters. Sealey run the SMC ladder across those sizes with the size stated on each socket rather than by machine.
Spindle work uses a different tool again. A spindle key covers 17, 19, 22 and 24mm across common front and rear axle sizes, giving purchase on a hollow spindle that no socket will grip. Brake piston pliers at 240mm spread the pistons back to accept a new pad. A torque figure applies to most of these fasteners, which is the other reason the drive size matters.
Engine and general work closes the leaf out with a piston ring compressing tool, a 40-in-1 ball wrench multi-tool covering cyclists and motorcyclists, and an 11mm hex brake caliper socket for Ford, Mercedes and Volvo calipers. Questions go over WhatsApp on 07754288583 with the machine and the fastener. The spindle key covers four sizes in one tool rather than needing a set.
