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.

[4] An advanced feature of the new Meteor engine was an invention to reduce valve failure, which they decided was caused by lateral vibration.

This effectively eliminated the 'rocking' action of the conventional top-end rocker and Vincent top ends set a new performance standard.

[1] 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.
