Triumph 5T Episode: 1947
Triumph Speed Twin. Distinctive appearance of the top of the engine. A post WW2 model as it has telescopic forks.
Norton CS1 Episode: 1947
Norton International Episode: 1947
It is a post Ww2 Norton, probably an International from the shape of the oil tank.
Norton International M30 Episode: 1947
He looks like Raine Lampinen, a great Finn rider of the time, and winner of Gardermo-Racet 1947. (The surroundings, especially the track, could very well be of an airfield.) The bicycle being then a Norton. Much, much later: it is a Norton. No telescopic fork, but plunger rear suspension make it a 1936+ motorcycle. Road racer winning Gardermo-Racet, 500 class, it can't be anything else than an International M30. Father of Simo the SAAB rally driver??
If https://fi.wikipedia.org/wiki/Simo_Lampinen is accurate, yes, my dear dsl.
Velocette KTT Episode: 1947
Maybe a Mk VIII KTT? - https://en.wikipedia.org/wiki/Velocette_KTT_Mk_VIII - among the first bike to have swing arm rear suspension.
BSA M20 Episode: 1951
These are WW2 era British military bikes and they are two different makes. One the left is a BSA M20 (front brake on the right of the bike) - http://farm4.staticflickr.com/3513/3885899154_8794200169_b.jpg and the other bike on the right is a Norton 16H with its front brake on the left side - http://img20.imageshack.us/img20/9168/bike1tp.jpg
BSA A10 Golden Flash Episode: 1953
From the shade of the colour it is probably an A10 Golden Flash.
BSA D1 Episode: 1953
BSA Bantam. This one has 'plunger 'rear suspension so it is probably a late D1 variant.
Velocette L.E. Episode: 1953
Maico Maicomobil 175 Episode: 1953
I think this should be classed a scooter. It's a touring motorcycle. I think discussion is opened now because even maicowerk.com web authors aren't sure: - It was not quite a motor cycle, and not quite a scooter, in fact it straddled somewhere in the middle with Maico claiming unpretentiously that it was an "auto on two wheels". It's a scooter. (What did I win?) a brand new empty box !
1952 Maicomobil MB175
Sunbeam S7 Episode: 1953
S7. What's the BSA plaque on front mudguard all about?? This is from Wikipedia, but the link is inaccurate so I can't quote it. In 1943 the Sunbeam name was sold to BSA. There is more to be found if you type Sunbeam Motorcycles into your search engine. Yes BSA had bought Sunbeam and envisaged it as their 'Lexus' type brand ! Thanks - interesting story. Seems S7 was pretty much a ripped-off BMW R75 design, but modified so it didn't look too German - https://en.wikipedia.org/wiki/Sunbeam_S7_and_S8
More 'Lambretta' than Lexus, perhaps, once the BSA Sunbeam scooter debuted in prototype form at the 1958 Earls Court Show. Manufacture of it, and its two-stroke cousin the Triumph Tigress, commenced the following year. Sales weren't too bad for a while and, today, some nicely restored examples can be found.
