1971 BSA B50 Gold Star 500cc


  • Impeccably presented
  • Reportedly in good running and riding order
  • Striking purple paint scheme

The Appeal

Following the great success of the original Goldstar during the 1950s and ‘60s, BSA decided to revive the hallowed name with their B50 which became the last of their large capacity single-cylinder bikes to utilise ‘unit’ construction. Known as the B50SS, the new Goldstar was an early proponent of the now immensely popular ‘urban scrambler’ aesthetic.

This 1971 example looks to be in really fine condition for its age with very little in the way of wear. The vendor informs us that it runs without fault and rides impeccably. There should be room in any collection for a purple Goldstar, so if there’s a corner of your shed that remains unoccupied, we urge you to consider this motorcycle.

The History and Paperwork

  • The registration number current displayed on the bike is incorrect as it should read MWV 586J
  • Exempt from road tax or MOT testing due to its age
  • V5C present
  • Three previous keepers indicated
  • The odometer reads 3,531 miles, which we’re unable to verify

The Condition

  • Striking purple paintwork in very nice condition
  • We couldn’t see any obvious dents, scratches or significant stone chips
  • The frame presents well, looks to be straight and there’s no corrosion to be seen
  • All of the chrome looks in good order and without noticeable pitting
  • Minimal wear to the seat upholstery and controls
  • Complete with a headlamp and indicators for road use
  • All the instrumentation appears in good shape
  • The chromed wheels present well, although the tyres appear a little perished

The Mechanics 

  • 500cc single-cylinder engine
  • ‘Unit’ engine and gearbox layout
  • Appears to have been fitted with an electronic ignition system
  • After rectifying a fault with the kickstarter using new old stock parts, the vendor informs us that this bike starts and runs well
  • It reportedly rides impeccably, with no faults to report


A lesser seen iteration of the legendary Goldstar, this bike represents an interesting period in BSA history.

It looks to be a very usable example and we enjoy the forward-thinking ‘urban scrambler’ look.

About Max Bids

The max bid process allows you to bid without any hassle.
Enter your maximum bid and we will then bid on your behalf to ensure you're the highest bidder - just enough to keep you in the lead and only up until your maximum.


C&C prevent auction snipers from bidding in the last seconds to win an auction.
Auctions are extended by 3-minutes if anyone bids within the last 2 minutes to allow other bidders to react and counter-bid.

Auto-bidding increments

  • If your maximum bid is equal to or below the reserve price, your maximum bid will be applied in full if you are the highest bidder.
  • If you are the highest bidder and place a maximum bid above the reserve, we will automatically put in the reserve as your first bid.
    • Once the reserve has been met, Car & Classic will make sure you are the highest bidder using only the bidding increments stated below.
    • We will keep you in the lead up until your maximum bid OR the increment closest to your maximum bid, providing your maximum bid is enough to cover the increment value.

Bid Amount Increment
£0 to £10,000 £100.00
£10,000 to £50,000 £250.00
£50,000 to £100,000 £500.00
£100,000+ £1000.00

Automatically outbid immediately

When you place a max bid and are outbid immediately that means that another bidder has placed a max bid limit which is higher than yours.
You can bid again and we will use our automatic bid system to try and get you as the highest bidder.

Matching max bids

When there are two max bids of the same value, the one placed first remains the lead bidder.

What are pre-bids?

A pre-bid means you’re able to place a bid before the official start of the auction.
You will be notified whether or not you are the highest bidder when the auction starts.

Problem with your bid

Bids are contractually binding. To help protect you, we have some rules in place if we think it's been mistyped. Please check and amend what you have entered.
