SOLD – BSA forks 65-5405 poss ’49 to ’57 B31 plunger, M series with 7″ brake, A7 B33 from 1949 to 52


BSA post war motorcycle telescopic forks. Possibly 1949 to 1957 B31 plunger bikes, and M-series with 7″ brake,

and BSA A7 / B33 from 1949 to 1952.

One fork leg has a cast number. 65-5405. I’ve spent ages researching that number and only one thread comes up. It seems that the person who owned them also wasn’t sure which model and year they were for.

They are being sold as you see them and needing refurbishment.

I am happy to provide dimensions if you are unsure if these will fit you bike. I have several pairs of BSA forks and they are all different. These ones have the welded mounts for the brake anchor, as opposed to the one or two studs / block that are fitted in a similar position.

Please make sure they are correct for your needs before you buy.

Other BSA parts: I have some. Please view the BSA items or get in touch.




  • International shipping available. Please ask.
  • Combined shipping available if you buy other parts. 
  • I usually ship to most destinations. If you don’t see a price, please ask. Shipping is in addition to the listed price for the item.

Viewing: Please come and check it over before you buy. It is at PE28, near St Ives in Cambridgeshire.

Collection: If you don’t want it shipped, I have plenty of space. If you can’t collect for a while, it’s not a problem. However, I will need to be paid very soon after the sale. Thanks.

Payment: This site has a facility to pay online. Good old fashioned money on collection is preferred. I can accept payment through PayPal or by bank transfer as well.

Import Taxes: Please note that IMPORT DUTIES are not something I can control. If you are buying from outside the UK, there is a chance that you will have to pay import taxes. Import taxes vary from country to country. If there are charges to pay, it is the buyer’s responsibility to research the cost and pay the duties. The price that you see on my advert is for the item and not the item plus whatever taxes might be due.
