This bike is a one-off made in the early seventies - who can identify engine and frame?

There's no such thing as a Munch engine. The frame is not that difficult to recognize...

Yep, it's a Norton frame. And Maaka is not far off with his guess of the engine.

This is a CAD drawing of an interesting concept bike - who can tell what kind of engine it is?

A Subaru diesel engine? Can you break the biscuit in two and give half to your dog?

Hmmm... you seem to be scanning the same websites as I do......

Or how would you know that it's a Diesel?

I guessed it was a diesel because I couldn't see any spark plugs and then there was that big pipe sticking out the front that reminded me of a lorry engine. So I just went to google and typed in diesel engined concept bikes and there it was.

Yep, that's right, and that is the bike they are rolling out. An american-made sport-touring bike with a pushrod V4. What's your take on that?

Definitely 1960s. Maybe a 'bitser' Honda/Suzuki?

Sorry Col you don`t count 555

I actually did some research though.

555 Cheers mate.
A rotary valved,twin exhaust port,2 stroke single must have been a rare breed back in the 60`?

I can`t find anything like it on the net so far.

Well it says "Suzuki" on the side...
This bike, or different versions of, must be very reliable - I still see some on the streets here in Thailand. Dual exhaust but conventional carb.
I'll take a pic next time I see one!
The other real old 2-stroke is the Kawasaki GTO 125, but I think you can still buy it new here, so it doesn't count.

Here's a pic of the '61 Colleda 250 TB with an air-cooled 2-stroke 246cc parallel twin, producing 20 hp/6.000 rpm and 1,9 kg-m/6.000 rpm. Suzuki sold their first bikes under the name "Colleda".
When the Cycle World magazine presented the Colleda 250TB in the USA in March 1962 the bike was called the Suzuki TB but you could clearly see the Colleda emblem attached to the white sidepanel, althought there's a Suzuki "S" logo on the engine. The 250TB was replaced in 1963 by the 250TC.

I spoke to the Thai owner.
He tells me it`s a Suzuki K125.
It had a Honda seat on it so a little confusing as i`d didn`t know of any Suzuki or Honda rotary valved road bikes.
The K125`s are popular here in Thailand with Classic bike enthusiasts.
