The Comstar wheel, sometimes referred to as Com-stars or stylised as ComStar,〔〔 was a composite motorcycle wheel that Honda fitted to many of its motorcycles from 1977〔〔 to the mid 1980s. Its design allowed it the option of being fitted with tubeless tyres and its use on the Honda CX500 was the first time tubeless tyres had been designed for a production motorcycle.〔〔 ==Background== The Comstar was Honda's replacement for the tension spoked wheel. Whilst spoked wheels offered a degree of flexibility to help absorb road imperfections, they also required periodic maintenance to ensure correct spoke tension and required the fitment of an inner tube. Honda claimed the Comstar design combined the strength of a cast wheel but allowed a predetermined level of radial flex like spoked wheels.〔 Comstar wheels also allowed the fitment of tubeless tyres which, like other alloy wheels,〔 helped to reduce unsprung mass,〔 although not all models fitted with Comstars had tubeless tyres. Honda debuted Comstars on their FIM European Motorcycle Endurance Championship winning〔 RCB-941〔 production endurance race bikes for the 1976 season.〔 Honda first fitted Comstars to its road going motorcycles in 1977 on models such as the CB400T Dream, CB750F2 and the later flagship CBX1000. A special lightweight version was also used on HRC's failed oval-piston four stroke GP motorcycle, the NR500,〔 and the later NS500 two-stroke ridden by Freddie Spencer.〔Wilson, Hugo.

This style of Comstar was often given an anodized colour finish such as gold〔 or black〔 with silver detailing.〔 They were said to be hard to keep clean due to tiny crevices.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Comstar wheel」の詳細全文を読む スポンサード リンク
