The Appeal
The S7 and S8 Sunbeams were designed by Erling Pope with styling loosely based on designs of the BMW R75, designs of which were acquired as war reparations by BSA. Built in Redditch, the engine in the bike was highly unusual being more familiar to that of a car rather than the tradition bike layout. The vertical inline twin, OHC 500cc unit was longitudinally mounted with a coil ignition and a wet sump lubrication system which, through a dry clutch, drove a shaft to provide locomotion to the rear wheel.
The S7 and S8 were very expensive when new with only modest performance gains, which is why they resulted in low sales volumes. The S8 was sold as a sportier model due its lighter weight, enabling it to reach 85 mph, it also had new BSA forks, a cast aluminium silencer ad chromed wheels.
This bike was purchased by the current owner’s uncle as part of his larger collection of weird and wonderful and varied machinery. Unfortunately, after his passing the collection was passed down through the family but now with a change in life circumstances the bike is up for sale.
The History and Paperwork
- V5 document in the current owner’s name
The bike is not thought to have had a lot of work done to it during its time in the collection aside from regular maintenance. Any work that did need doing would have been done by the previous owner and therefore the paperwork would not have been kept. The condition of the bike however shows that it was well cared for during its time.
The Exterior
- Frame and panels in good condition
- Wheels in good condition
- All electrics reported to be working
- Seat fabric is in great condition also
The Sunbeam is a fantastic looking bike with the spring seat reminding us of tourer bikes of the same era, the engine configuration however is something that sticks out as being something different.
The overall condition of the frame is good, there is some general wear and tear and there is a small amount of surface corrosion starting to show but it’s really very minor and certainly not at the levels you’d expect for a 69-year-old vehicle that has over 41,000 miles on the clock. If we look at it in that aspect, it’s in very good condition indeed. The frame has no structural damage or anything obvious wrong with it from what we could see, after a rub down and a lick of paint it would be as good as new.
The wheels are in good condition although are starting to see some corrosion coming through the rims, the tyres would also need to be changed as the rear has a flat. The handle bars look to be in great condition and the centre dial on the light pod although looks a little tired is still in good overall condition and is reported to be working as intended.
The Mechanics
- 500cc parallel twin, OHC four stroke engine
- Engine exterior in great condition
- No visible leaks or damage
The bike has sat for a few years in storage underneath a cover so will need some simple, light recommissioning to get running, a battery change, a fuel flush and a spark plug change is all that the owner believes should be needed. The exterior condition of the engine is fantastic as you can see from the photos, no fluid leaks or other worrying signs to see.
The mechanisms are reports to all work as they should with the kick starter and gear lever all moving without freely. The bike rolls freely despite the flat rear tyre and the stands kick down without issue. The tyres are getting a bit old and as you can see have started to split due to being dry and aged, it might be wise to change these before attempting a ride.
The exhaust looks to be in great condition too with no visible cracks or splits in any of the joins and the entirety being dent and damage free from what we could see on the day. The rubber bushing for the shaft looks to be whole and not split from the small section you can see from the exterior.
Summary
The Sunbeam was an innovative bike that offered something different from the standard, it was perhaps not as popular with buyers back in the day, but they have a dedicated and loving fanbase now. The production number of the S8 are believed to be around 8,530 so represents quite a rare beast. This one has a great back story and has clearly been looked after, it needs only a little TLC to get it back on the roads and commuting to shows in the glorious British summer time.

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.
Anti-sniping
Car & Classic 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 £9,999 | £100.00 |
| £10,000 to £49,999 | £250.00 |
| £50,000 to £99,999 | £500.00 |
| £100,000 + | £1,000.00 |
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.
Pre-authorisation
We may hold a pre-authorisation charge on your card until the end of the auction when the hold will be cancelled. If you win, we'll take a security deposit which counts towards the payment for the vehicle and isn't any extra cost to you.
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.
