Hey, if you're rebuilding the rear wheel on your old Honda dirt bike, this spoke set from CRU is exactly what you need. It fits a bunch of models: the CRF100 from 1985 and up, the XR100 from 1981 and up, and even the XL100 from '79 to '85. The spokes are 153mm long overall, with a straight section of 149mm (about 5.875 inches), and they're 3.15mm thick. They use a standard 5mm spoke wrench for tightening. This set directly replaces the OEM part numbers 97488-42136-K0 and 97338-42137-K0. Just lace 'em up, true the wheel, and you're back on the trail. Super straightforward for a standard wheel rebuild.
