Beautiful exotica. Nice, nice, nice! Good find.

Unfortunately the ESO scrambler announced in the above clipping didn't live up to the hype. The frame might have been 'sort of' like a Metisse but what was missing was the Rickmans light weight and impeccable handling. Apparently the ESO didn't corner very well and some reports mentioned that it seemed top heavy.
The unit construction engine however was a gem, basically a lowered compression Speedway ESO (Jawa) motor with an integrated unit construction 4 speed transmission. Aftermarket frames appeared in small batches, especially out of Sweden with bikes like the EGM. The first world 500 champion Sweden's Bill Nilsson fitted one to a Bultaco Metisse frame and many modified the stock frame to try and improve the handling.
While the ESO wasn't all that popular in the west, they were the hot ticket behind the iron curtain where bikes from the west were hard to get. Today, ESO's are right up there on the pre 65 collectors desirability chart and some folks have built all sorts of hot rod specials using the engine.

Here's an EG made by Egon Gustafson in Sweden. It's now owned by Alan Jones here.

i just love checking out old speedway outfits. they are so compact and all engine. the myriad of variety from that pre Japanese era always intrigues me.

There was one recently in Scotland. Don't know where it ended up though.

That was John Wilson's bike up in Scotland which was recently purchased by Dean Rowe here in Oz.That makes the only two Unit ESO Metisse's that Pat French built are now living here only two hours apart. ;D

LOve to see that outfit, or own it !!
on then ESO solos, where are the mag's gone ? and are they total loss or whant the go with th eoil are they recirculating it and if so any fotos of what under the cover and are they still using a pilgram pump ?
-
That twin motored ESO outfit is an interesting piece of kit. Do you have a close up of the engine layout?
-

There's supposedly another stock ESO scrambler, believed to be a late 50's long stroke version, living in a dismantled state in the Hunter Valley. Apparently the owner's an expat Czech who's not interested in selling it or even showing it to anyone. Jonesy's got two bikes (Black Betty and the EGM) and a couple of spare engines in his collection.
Although I've posted these photos elsewhere, I reckon it's more at home here. 1957 World 500 motocross champion Bill Nilsson was legendary for his trick specials, especially the Crescent on which he won the title.

http://www.lindstrom-mx.se/bison2.htm (http://www.lindstrom-mx.se/bison2.htm)
In 1964 he fitted a unit ESO engine to a Petite Metisse frame orifginally designed to take a Bultaco engine to compete in that years World 500 Motocross Championships. The bike, from all reports, performed really well but a mid season broken leg ended that assault on the title. As shown in the photos, Bill still owns the bike in unrestored condition, exactly as it was last raced........It's interesting to compare it to Black Betty.

It's hard to tell on such a little photo but it looks like a BSA frame. However the engine looks as if it's a speedway version going by the oil pump on the primary cover and what looks like alloy engine plates in there housing a separate gearbox. My eyesight ain't what it used to be so it might well be a unit motor.

Really sweet example and much info/history in VMX Magazine #19 .Interesting modifications done by Bill Nilsson on page 12.
Eso means Ace in Czech-a winning card in every sense 8)

You just jogged my memory ..yes it is a speedway converstion/version ..thanks
photo 41 shows a better shot

It's a nice bike anyway.....another engine swap bike that should be over on the 'Wacky Engine Swaps' thread.

Here's an early, mid fifties ESO MX. It makes an interesting contrast to the mid sixties version shown previously.

What emerges from showing these ESOs is that it debunks the common misconception that the scrambler motor evolved from the speedway engine. In fact, the reverse is what happened, the ESO unit MX engine preceded the speedway motor by nearly 10 years.

It has a pre unit BSA gearbox with foot rest bolted on through the cover studs.

Follow up on the Eso/Bsa this is a Cheney frame not a Bsa and a pre unit not the Unit ESO that is in a shed near Perth
