Bike experts - guess the rusting bike

[outlawtorn]

Cool pic, now can someone tell me what bike this is?

[Finn]

Looks like a brand new GN250 being delivered.

[dogsnbikes]

Its missing the anchor chain......

and there is only one bike that attaches to them

Its a "harley":woohoo:

[Pussy]

Early-mid sixties Yamaha 125?

[James Deuce]

There are no bike experts on KB. Just strokers.

[Dean]

BSA bantam or whatever its called, its old, looks like a single cylinder thumper.

Or an old triumph, indian?

[MSTRS]

Early-mid sixties Yamaha 125?

My guess....except the chain/guard is wrong side. Still thinking Jap, tho.

[nudemetalz]

It's a twin cylinder single carb 2-stroke, thinking Yamaha. My guess is YD-2.

[Mikkel]

If it is japanese it'll still start!

[Blackbird]

It looks like a Suzuki T10 250 from the 60's BUT no-one has commented on why the chain drive is on the right so maybe something like an MZ or CZ?

The Yamaha has it's chain on the RHS.

[Blackbird]

The Yamaha has it's chain on the RHS.

Yep, but pretty sure that none of the YD series had fork gaiters whereas the Suzukis did (God, I'd better get an anorak and a train spotting book:shutup:). Maybe you can tell me I'm wrong and make me feel a whole lot better :yes:

[nudemetalz]

That's true, but remember it's a 40 year old (dumped) bike and people did all sorts of mods back then. May have had YDS forks put on it.
Sheez, I'm sounding like a geek here but I like my classic Yamahas (hence owning the YG1)

[outlawtorn]

One thing I do like about the bike is the rust free luggage rack at the back of the bike....

[pzkpfw]

It looks like only one spark plug poking out, in the centre of that wide-looking head.

[Blackbird]

Yeah, looks a bit suspicious!

[pritch]

Still looks to have a strong family resemblance to the Yamaha YDS3 from about 66. I went for a nice ride on one in the tropics - keeping an eye out for water buffalo... The YDS3 has/had the chain on the right.

[Drew]

I think the picture is trasposed. Seems like the clutch cable is coming off the right hand lever.

Edit; nope, the writing on her wet suit is the right way round.

[Ixion]

YDS2/YDS3 never had a fully enclosed chain. And the headlamp is worngA , they had a sort of binnacle on top.

I thgink it's smaller than 250. Def a two smoker twin, probably Yamaha

researching, researching

[Taz]

Searched everything I have and still no closer to I'd-ing this bike :cry:

[Blackbird]

I wonder where the photo was taken and whether it's one of those obscure Asia-only models? Like you, I can't get a match as there are parts of the bike (fully enclosed chainguard with fork gaiters)which don't seem to go with other parts if we're guessing an early Yamaha so maybe it's a bitsa!

Ah but the YD-1/2/3's did.

It's got one spark plug. In the middle of the head. It's a single.

[SPman]

Yamaha YA125.

[Taz]

Yamaha YA125.
Chain on the wrong side.

[nudemetalz]

Plus the YA is a semi-cylinder forward design.
Despite the central plug, I still think those fins and crankcase are too wide for a single cylinder.

Ever seen an MZ, ETZ250? Externally, the motor looks like a 600 single.

Dunno if I'm convinced it's a two smoke yet. Looking again now...

Edit; definately a two stroke single. The pipe appears to come from the side, but looking closer it comes out scewiff from the barrel.

As to what it is, still non-plussed.

[Str8 Jacket]

BSA bantam or whatever its called

Looks a bit big and/ or Japanese-like to be a bantam IMO...

[nudemetalz]

Yeah, have seen the ETZ's. They have quite a square looking barrel and fins.
This has vertical cooling fins on top.
No, I'm convinced that the enclosed chain is Yamaha type, as to what it is :confused:

Definitely going to go through my classic Yamaha book tonight as this is bugging me now !!

[MSTRS]

Racking the brains (and Google), but I am still with those who say it is a 60s Jap 2 stroke twin.

[Pussy]

You blown up an example of that bike, Hels? :whistle:

[Str8 Jacket]

You blown up an example of that bike, Hels? :whistle:

haha! NO! :shake:

Probably every other example though.... :(

[James Deuce]

Oh FFS, it's a DKW RT350.

The front down tubes have fallen off I reckon, but that is a DKW tank and headlight.

[Str8 Jacket]

Oh FFS, it's a DKW RT350.

So it *is* a smoker twin then...

[paturoa]

What about this??

http://www.powerdynamo.biz/deu/systems/7119/yds3foto.jpg

[Taz]

The rusty one has no front down tubes. I thought Zundapp at first but no.....

[James Deuce]

What about this??

http://www.powerdynamo.biz/deu/systems/7119/yds3foto.jpg

Nah. Tank's too small relative to the rest of the bike.

[MSTRS]

Oh FFS, it's a DKW RT350.

The front down tubes have fallen off I reckon, but that is a DKW tank and headlight.

Nup. Those things have a leftside chain...

[James Deuce]

Not in the reversed photo I just looked at! It's on the Internet! It's right!

[MSTRS]

MZ...?
<img src=http://www.realclassic.co.uk/mz04092702.jpg>

[James Deuce]

Nah. Head cooling fins are wrong and the tank pads are too big. That's a DKW tank on the submersible, I'm sure of it.

[MSTRS]

It is at about this point that I find myself calling the OP a complete and utter bastard.
I mean, he hasn't even been back to gloat etc...

[McWild]

Don't know about the bike but I think that's a robot mermaid in the background.

[Mystic13]

Yep, and even though some character parked it here they still chained it to make sure no one makes off with it. Some where there is a guy who chained his bike up 40 years ago and can't remember where he parked it.

And the round badge on the tank fits two Japanese marques that I can think of. And as for single / twin. I wonder if the rider/diver is single and has a twin?

If one of you lot can figure out what bike this is I'd be impressed.

[Slyer]

The tank pad and round badge screams Yamaha. But damned if I know what it is.

The bike is odd because it has a massive tank and tiny motor.

[dmouse]

yup thats about right, the uk was flooded with them in the late 70`s to early 80`s MZ and another though they looked like the same mould a CZ

[Taz]

There was a jawa badged MZ. I worked for the NZ MZ importer at one stage but luckily by the time I started they were getting out of them.

[klingon]

...the uk was flooded with them ...

:killingme

[Drew]

I cant find a bigger pic of this model, but it looks close.

[Blackbird]

I posted the photo on 2 of the international Blackbird websites out of sheer curiosity. The lines of debate were remarkably similar to here but the closest was a CZ 175 from the late 60's or early 70's. It had a raised horizontal ridge on the back of the gearbox, fully-enclosed chain on the correct side and the tank was virtually identical. The knee cut-outs were a slightly different shape though. Guess we'll never know but thanks for the fun:Punk::Punk:

[gwigs]

Honda Cousteau 66 .....250 breast stroke engine......carbs were prone to flooding.:blink:

[vfxdog]

To me it looks like one of the many variations of Puch sold as Sears and Allstate brands in the US. Mid to late 60's. Can't be bothered figuring out exactly which one.

[SoftRider]

Its a B120- Suzuki- I;ll stake my cherry on it!- my uncles got one in our shed.

[Drew]

Better go take another look at his then. The cylinder on the B points forward, and the carburetta is on the side, not the back.

Give me your cherry!

[SoftRider]

Whats that big shiney thing between your legs on your profile Drew?

we should talk.

[vfxdog]

Yep- guard that cherry- or your uncle is very skilled at moving chain drives from left to right.

Those are called forks, mountain bikes have those dont they?

[SoftRider]

The pics reversed silly- cant you see that!

Look at the divers REG :woohoo:

[Drew]

I thought that too, in fact I had to post a retraction. Look at the writing on her wetsuit.

I have an unfortunate tendency to look straight at the chest. Luckily.

[Ixion]

Chain's on the same side as the throttle twistgrip. Only bike I know of with a left side twistgrip is the old Indian. it ain't an Indian

I'm resiling from yamaha, joining the "somethin 'orrible from beyond the Iron Curtain' group.

[rok-the-boat]

I'll have one of those chrome racks - still lookin' good.

[nudemetalz]

To me it looks like one of the many variations of Puch sold as Sears and Allstate brands in the US. Mid to late 60's. Can't be bothered figuring out exactly which one.

Actually I agree now.
Believe it's a (possibly 1966) Sears Allstate 250 twingle.
This makes sense with the bike cylinder(s) and one spark plug. The "twingle" is a split cylinder 250 with 2 pistons one behind the other with seperate conrods.

[Kickaha]

Ever seen an MZ, ETZ250? Externally, the motor looks like a 600 single.

.


Seen one? I've done better than that I've raced one

[ynot slow]

Can't indentify it,but it is modern as it is water cooled.:bash:

[Drew]

Seen one? I've done better than that I've raced one

How did you get it not to snap chains?

I couldn't believe it, when we removed the chain covers, to find a 510 chain! My A50 used to eat them up!

[MSTRS]

Actually I agree now.
Believe it's a (possibly 1966) Sears Allstate 250 twingle.


Nup. Have to admit, it was an early pick of mine. But...been flicking between your pic/s and the watercooled version....the engine at least is all wrong. Too big and rounded.
The original pic looks photoshopped. The diver seems too 'crisp'

The bike in the first pic, is missing a cradle in front of the motor, I thought that was how it was made, but looking at the angle the motor is on, I wonder if it wasn't removed by whatever dive company put it there for tousists.

[Kickaha]

Muffler fell off after 3 laps so it probably wasn't going long enough to have chain problems

Buckets were out accelerating me:rolleyes:

[zx rider]

I think it's a Suzuki b120. Old Suzi round tank badge, fork gaiters, single cyl, enclosed chain, big headlight shroud,and about the longest tank on any small bike. Probably a blue one eh!

[Taz]

Not a B120

Nope. Look at the chain side...
