Great looking bike. Fantastic restoration. The front wheel looks like it is from an '81 Montesa VG414?

  thats a gem ! what model/capacity and are there any or many in Aus  ? 

[maico police]

Sorry but that's gone a bit mental. Looks like it'd be a full time job keeping the chain on the thing.....
(and probably have the straight line stability of a Maltese shitzu on crack cocaine).

      The geometry looks just like any other evo era bike to me ! it still looks trick , personally id rather a 77  'mk10

I think Ross is referring to the agle of attack of the swingarm with the shocks fully extended. The chain is pulling over the swingarm pivot meaning the engine will compress the suspension seriously under power and the swingarm will be sawn in half by the chain.

The shocks are around 25mm (at least) too long.

If you compare it to most EVO bikes that are set up correctly the swingarm angle of attach is usually much less. I am not referring to all those HL500 things with massively over length shocks to try and get 13" of travel from a 10" travel frame/swingarm setup (I'm just using the HL500 as an example not trying single them out).

    Agreed the rear does look too high , they look like (longer?) aftermarket ohlins and if it were mine id drop the whole thing at least 2"-3" just for the ease of living with it (and conering) - it's still a big"yes please"

 Twist my arm and I'd take it as it is but lower the thing and loose the yellow fork legs.

It looks like a Mk15 420cc Pursang, or is a nice copy of one. The last Bultaco produced.
All the pictures I have are showing slight differences to this one, like swing arm, frame brace, painted engine (not even considering the Exh pipe & odd front brake on it), but then I'm not even sure any were made for actual sale.

I think Mk15 125 & 250s made it to market but not sure about the open class bikes. It was domestic market only for the few that did make it I believe. Pictures of the 125 I have seen show it to be  afantastic looking bike and still shows that the engineers at least were looking ahead. I'll have to try and find the photos.

You are right the Aluminium swingarm looks like it is off a single shock bike modified to fit as the shock mounts look added on and the brace in front of the wheel seems to be for some sort of linkage.

The front wheel looks very much like the 'assemetric' fronf brake and wheel from my VG414 Monty with a mount plate to adapt to the Simons forks (I assume they are genuine) and yes Ross very yellow.

The builder of the bike contacted the magazine over a year ago and we've been trying to feature it ever since.  So far though he has only sent us low res images not suitable for publication.  It will happen.

It's definitely a copy. The MK 15 used a completely different motor. That motor is probably a mk12. It's a real Mk15 tank though.

I think Mk15 125 & 250s made it to market but not sure about the open class bikes.

Is that right? I wasn't sure if they ever made it to production.

I found the pic on Hugh Weavers facebook page (just search for Bultaco).
