what is it????
 
this bike is in to have the frame repaired.
do you know what it is?

hints
it's a vee twin.
has side valve inlet and overhead exhaust valves.
it has primers on the heads to add fuel for starting.
the engine is made by the same company who made the bike (not an adopted engine )
it uses a sturmey archer gearbox.

i've blurred the name out. i must admit i've never heard of it.

originally thought it may be a royal enfield or may be a 14hp zenith

but then the M under the case seems to err towards a matchless

so will stick with matchless

John Hopkins 05-03-2009 12:36 AM

Thats not a matchless, looks like it might be a J.A.P. engine (their bikes were called S.O.S. so obviously superior) somewhere around the 1930s..

looks like an anzani by the british company AJW.
600cc perhaps.

John Hopkins 05-03-2009 01:30 AM

No its a Martinsyde V Twin 1920s.

If it's a 678cc quick six it is priceless.

only a few Martinsydes left and the cheapest would fetch about 10,000!

When you have finished it take it for a short test ride and get a photo of you riding it. (your five minutes of fame.)

Well if it's yours it's worth rebuilding, they are as rare as hens teeth!

Here is a pic I found on Wikipedia of a Martinsyde model C, 498cc.

And here is a link to a review of the Quick Six. A rare and very much sought after bike indeed.

i thought sos motorcycles were 'super onslow specials' built by the late len vale onslow, formerly britains oldest working man and oldest motorcyclist, still working in his bike shop and still riding his own bikes on his 100th birthday iirc.

Thats right they were. They made up three sets of what the S.O.S. stood for, I can't remember the third, I think they were just to get the brand into everyones heads.

They are johnr. I did an interview with him about 10 years ago. A real Biker and a Gentleman.

dracken1 05-03-2009 05:09 PM

no it's a customers bike. and he has a spare engine....

there are supposedly only about 30 left.
and the quick six only one is known which i believe was auctioned last year for silly money.

i think this onw we have may have been in that fire in birmingham.

I found this in a British motorbike site

Super Onslow Special, later named 'So Obviously Superior' because they offered high quality products. Founded 1927, closed in 1939 at the onset of war. Models made with JAP and Villiers engines. Made water-cooled engines in 1932. Taken over by Tom Meeton in 1933 who added optional foot-change gearboxes in 1934. All-weather models offered deep-valenced mudguards, leg shields and under-shields. Also sold tuned versions under the name Meetons Motor.

walked past onslow`s couple of weeks back its a shame to see the ceilings collapsed in over what was left of the bikes in the shop and how run down the areas become
