1971 BSA A65L Cafe Racer

Up for auction on eBay with about a day left is this nice-looking BSA Lightning. The seller seems to have done a lot of work to it (details copied from the original listing and pasted below), and it certainly looks the part. Interestingly, the bike seems appear to have a mechanical/hydraulic hybrid front brake (see the last picture below). I think it wouldn’t be inappropriate to have a brake reservoir on the clip-on givent hat it is a disc front brake, but I appreciate the stripped-down look. Overall, a very clean build with classic good looks.

And I forgot to add this in originally: no chain.

I think this is the hidden brake reservoir the seller is talking about...
