Comstar wheel Disassemble" stamped on the wheel rim alongside other markings such as the fitment size. For its use on the NR500 GP machine, the wheels were made from magnesium with titanium used for the fasteners. Composite wheels were also cheaper to produce than their cast alloy equivalents. From the early 1980s Honda had begun equipping newer models with cast wheels called ComCast stating "...that technology has solved the casting porosity problem and that cast wheels are now used on Hondas for styling and marketing reasons". ComCast wheels were a combination of pressed-together cast aluminium hub and spokes with a hollow extruded
Wheel hub motor part of the motor follows, or tries to follow, those fields, turning the attached wheel. In a brushed motor, energy is transferred by brushes contacting the rotating shaft of the motor. Energy is transferred in a brushless motor electronically, eliminating physical contact between stationary and moving parts. Although brushless motor technology is more expensive, most are more efficient and longer-lasting than brushed motor systems. A hub motor typically is designed in one of three configurations. Considered least practical is an axial-flux motor, where the stator windings are typically sandwiched between sets of magnets. The other two configurations are both radial
