Rim halfs were spinned, which increased material strength further, whilst using a wax coating - then anodised immediately afterwards.
Made by Tony Dawson of Dawson Harmsworth Ltd, Astralite wheels were used on Hejira and Hesketh, among others.
Production began in 1977 and by 1989 sales had grown to 1500 wheels annually. The following decade brought financial difficulty and production ceased in 1992.
Tony Dawson also built FTW and Scitsu Motorcycles.
