This web page was created to provide an information exchange mechanismfor BSA A10 Super Rocket owners. Most of the information on this webpageis based on: BSA Super Rocket sales brochures and literature, tips fromother A10 Super Rocket owners on a British internet motorcycle discussiongroup [Brit-Iron or britbike.com], and on lessons learned during the actualdisassembly and rebuilding of an A10 Super Rocket.
This webpage serves as a supplement to existing A10 informationsources and addresses weaknesses in the most popular BSA literature (i.e.,Haynes manuals, Roy Bacon books, Chiltons manuals, etc.). This webpageis not intended to address full BSA restoration details already documentedsufficiently in the literature. Even though most of the information inthis webpage is specific to the Super Rockets, some of the informationcould be useful to other A10 model owners.
This site has some coverage of other model A10s and A7s (especiallyin the photos section). I have even included even more information on SpitfireScramblers (especially the A10 goldstar Spitfire Scrambler). You will alsofind information on Golden Flashes, Road Rockets, Royal Tourists, SuperFlashes and other A10s.
