BSA C15 Cylinder head & Rocker box with rockers 40-206 #1

I’m having a clear out of miscellaneous parts that have gathered over the years. I had this head unit when I happened to have a BSA C15 engine. This top end comes with the rocker caps and outer cover, together with some oil lines. To make packing easier, I might separate the oil lines.

The rocker cover has the rockers fitted. Rocker box is 40-0206. The cylinder head (40-121) has a broken fin on the underside. Apart from that, it’s in decent condition. The valves are fitted.

However, it has been sat in my place for a while. It will need taking apart and cleaning at least.

Other BSA parts: I have some. Please 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.
