Kamikaze Chop

BSA custom motorcycle
This is one of those motorcycles where information is frustratingly scant. I think it’s based on a post-War Triumph, maybe a TR5 Trophy with the 498cc OHV four-stroke twin. (It has an Amal 276 carb.) [See comments. —Ed.] The bike was built by an underground Kyoto workshop called Kamikaze Chop, and it was wheeled out at the Joints custom show the other day. Visiting US luminary Jeff Decker selected it as his pick of the show; can anyone supply more information about this beautiful machine?

    Very clean, tasteful and dare I say…classy! Well done. I’m formulating a “Bobber plan” and this bike really has some nice ideas.

    err….it’s a BSA Golden Flash, no?
    Early ’50′s.

    Certainly a BSA. Looks to be an A10 of around 1949-50 vintage. I can’t tell the exact model from the photos.

    Cool bike. Bit of a speedway bike feel for me.

    Way cool! Looks to be a BSA A10 – Golden Flash or A7ST Star Twin in mostly stock trim. The front end with the rear set damper knob looks to be from a BSA C Model from late 30′s. Can’t seem to place the tank.

    Yep, it’s a Beeza for sure, and a very nicely styled one!

    erm my first thought was…..it is a BSA, a Birmingham Beauty……am I daft? It is a BSA isnt it?

    Thanks for all your comments: it does look like it’s a BSA A7:

    I think I might have owned one.

    She is definately a Beeza, the engine is an A10 Golden Flash early 50s and the frame with the rear plungers are probably from the same era…. cant seem to place the model that the front girders have come from. The petrol tank is from a Madras Enfield bike.

    Yup…… BSA…. verry nice….

    Simply stunning! I would love to see more of that front end/headlight setup. It has some slight Steampunk Hues…

    Doubtless it’s a BSA lump in there – but a nice ride all the same – tank logo and crossed guns on engine case should have been a giveaway eh?!

    It’s a 1950~55 BSA 650 A10. ( I have a 1952 version)
    The engine on swing arm frames is slightly different (was separate transmission instead of semi-unit construction, as re-invented by Harley Davidson a few years ago)

    Gas tank looks like Royal Enfield

    Completely aside from the provenance of the bike, I’d like to posit that the upper and lower photographs here are a pretty good illustration of how much of a difference the right background, lighting, and camera angle can make in the quality of a photograph. The bike in the top photo is immediately stunning; the one in the bottom photo is hard to see among the visual clutter.
