The Vincent Meteor is a British motorcycle designed and built at the Vincent works in Great North Road, Stevenage, Hertfordshire UK. Developed from the Vincent Rapide by Australian engineer Phil Irving in 1935, the Meteor was powered by Vincent Motorcycles first in-house engine〔(【引用サイトリンク】title=Vincent Black Knight and other twins )〕 and was one of four 499cc single models. As well as the 'standard' Meteor, Vincent produced a sports version, the Vincent Comet, as well as a TT racing model which shared many of the same cycle parts.〔(【引用サイトリンク】title=Vincent )〕 ==Development== Vincent-HRD began in 1928 when Phil Vincent acquired the name, as well as all the jigs, tools and patterns of the HRD Company. Vincent started with engines from other makers such as JAP and Rudge but problems with supplies led to the development of his own 500cc single in 1934. Vincent is quoted as saying at the time "...we never wanted to see another Jap engine as long as we lived and decided we should design and manufacture our own." Designed by Australian engineer Phil Irving, the new engine was developed over three months and the prototype Series 'A' Meteor was refined and developed into a production model, the Series 'B' Meteor, which was produced at the same time as the Series 'C' Comet, with the main differences being the new ''Girdraulic'' front fork fitted to the Comet while the Meteor had traditional Brampton girder forks and a slightly smaller carburettor.〔(【引用サイトリンク】title=1949 Vincent-HRD 500cc Meteor )〕 An advanced feature of the new Meteor engine was an invention to reduce valve failure, which they decided was caused by lateral vibration. A special design of upper and lower valve guides, without a centre section, meant that the valves had no fulcrum and into the central section they fitted a forked rocker pressed onto a shouldered valve stem. This effectively eliminated the 'rocking' action of the conventional top-end rocker and Vincent top ends set a new performance standard. 〔 When production of Series 'B' models was phased out in 1950 the Meteor was dropped from the range, making it one of the rarer post-war Vincent-HRDs.〔 Falling sales of expensive motorcycles led to closure of the Vincent works in 1956. 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「Vincent Meteor」の詳細全文を読む スポンサード リンク
