1950s BSA A10 Super Rocket 650 Valuation Report

Date: August 2025

Historical Overview

Launched for 1957 as the sporting evolution of the A10, the Super Rocket gained a higher-performance cylinder head, Amal Monobloc carburation and stronger brakes, quickly becoming BSA’s flagship 650 twin. Within the 1950s, values typically split between the early 1957–1958 bikes and the late-’50s 1959 machines as detail changes and presentation vary. UK buyers prize originality (matching engine/frame with correct A10R/DA10R cases), tidy tinware and credible history.

Value Influencing Factors

• Originality & correctness: Matching engine/frame, correct A10R/DA10R cases, alloy head, proper tinware and instruments.
• Mechanical condition: Evidence of recent engine/gearbox work, charging and brake overhauls pushes to the top of each band.
• Presentation: Quality paint/chrome, straight guards and undamaged tank badges materially help.
• Documentation: V5C, period invoices and restoration photos increase confidence.
• Venue & timing: Major UK motorcycle auctions (e.g., Stafford) and spring/summer listings outperform winter classifieds.

Conclusion

In the UK, early 1957–1958 Super Rockets commonly achieve £5k–£7.5k when roadworthy, with very good examples at £8k–£10k. Late-’50s 1959 bikes sit a touch higher for smart riders at £5.5k–£8k and £8.5k–£10.5k for excellent, documented machines. Projects span roughly £1.9k–£3.5k depending on completeness. Originality, mechanical health and provenance are the primary value drivers.
