Why You Need This: Spoke wheels are a fantastic piece of engineering; while simple in design, they remain as relevant today on modern motorcycles as on the vintage Honda CB, CL, SL, and even CT series of the 1960s and 1970s. However, every now and again, they need adjustment to be "trued" up, as bumps, potholes, and road abuse can cause the wheels of your vintage motorcycle to become wobbly or out of round. Truing of a spoke wheel is done by loosening and tightening the wheel's spokes to bring the rim back into alignment.
Yes, we know that many of you have been using a spoke wrench that is "close enough," aka a small adjustable wrench or even "vice grips" (no, we have never done that ourselves... ). Truth be told, we always wanted a good spoke wrench for our bikes; however, none exist. Thus in proper Common Motor form, we decided to make our own. Our Common Motor spoke wrench has the two sizes most commonly found on bikes through the late 70s. Larger bikes from the CB175 up to the CB750 use the 5.7 mm size, while smaller bikes like a CT90 or CB125 use the 4.3 mm size. We wanted to make a size-specific wrench that fit the spoke nipples snugly for the best grip and minimal slop; compared to the multitude of generic wrenches with close enough sizes on them and the tendency to round off the spoke nipples during adjustment.
The wrench is made from 1/4" thick cut steel, zinc coated, and comes with a lifetime warranty from us here at Common Motor.
Installation Tip: Spokes are rarely turned, and often, they have not moved since the wheel was assembled at the factory. Thus a little penetrating oil on the threads of the spoke will help ensure the nipple moves freely. Often moisture has gotten trapped between the tube / rim strip and the spoke nipple from the inside of the rim. It may be necessary to remove the tire, de-rust the back side of the spoke nipples, and apply penetrating oil before adjustment. Actual spoke adjustment is made in small increments in between groups of 3 to 4 spokes. It is best to use a truing stand with a dial indicator to make the truing process as accurate as possible. See your service manual for more detail.
