Common Issues to Check

• Oil Leaks: BSA twins are notorious for minor oil leaks, particularly from pushrod tubes, primary chaincase, and gearbox. Check for excessive drips.
• Electrical System: Original 6V electrics can be temperamental. Check for working lights, charging, and any signs of amateur wiring modifications.
• Engine Noise: Listen for excessive tappet noise, big-end knock (a deep thudding from the crankcase), or unusual gearbox sounds indicating wear.
• Primary Chaincase: Inspect for wear in the primary chain and tensioner, as well as the clutch operation, which can sometimes be stiff or draggy.
• Frame and Wheels: Check for rust, cracks in the frame, particularly around stress points, and ensure wheel rims are straight and spokes are tensioned correctly.

Running Costs

• Fuel Economy: 45-60 mpg (depending on tuning and riding style, respectable for a classic 650cc twin).
• Insurance Group: Specialist classic insurance, typically low cost (not covered by standard car insurance groups, but often very affordable for agreed value policies).
• Servicing: Relatively straightforward for a mechanically minded owner, but requires regular attention (oil changes, tappet adjustments, chain lubrication) more frequently than modern vehicles.

Which Variant Should I Choose?

• Golden Flash (A10): The original and most common A10 model, offering reliable performance and classic styling, ideal for those seeking a dependable entry into classic ownership.
• Road Rocket: A sportier version with higher compression and performance camshafts, perfect for riders wanting a bit more urgency and a livelier ride from their classic.
• Super Rocket: An evolution of the Road Rocket with further performance enhancements, making it a powerful and desirable option for those seeking the top-tier A10 performance.
• Rocket Gold Star (RGS): The pinnacle of the A10 line, combining the Super Rocket engine with Gold Star cycle parts. It's highly prized, very fast, and commands premium prices, appealing to serious collectors and performance enthusiasts.
