That's cool David, I never thought about Yamaha doing a works OW type trials bike....it was using the same rear monoshock type suspension that the 73 YZ works motocrossers where using. 11 years later they made a production mono trials bike....at least the MXers got it the next year (YZ250/360 B). The engine cases look huge....big flywheel maybe and I wonder what engine capacity (500cc...SC500 TY?...LOL). The fuel system is weird though. Trick looking trials bike for 1973.

One of the 'fuel injection' carbies came to Australia and Peter Paice tested it for several months but was given no information, assistance or alternative parts to try and tune it for local conditions.

He says that it was excellent when conditions were right but was easily put out by altitude or atmospheric conditions. He was not permitted to make adjustments so returned it to Yamaha.

Brand new. Out of the box:

Why do you pommies build up these lovely specials, and then put brown seat covers on them?!

[David Lahey]

Nathan are you assuming that bad taste is limited to bikes built by pommies?
I think this replica might have been put together in the Netherlands (where a lot of the development of the works Yamaha trials bikes was done)

[David Lahey]

Pretty sure the original had a brown seat cover too

[TooFastTim]

Nathan, the motor is a works engine. The rest of it (including the seat cover) is an EXACT replica of Mick Andrews' OW10 trials bike. It was built by Ferry Brouwer who used to be Ago's mechanic. So it's pretty special.

It's clearly an awesome thing - loving those fork drop-outs - and I can appreciate the quality of the bike.
But someone, somewhere said "Yep, what this beautiful bike needs is for us to upholster the seat using the back of an old couc"...

And then some poor bugger 40 years later is building a beautiful replica, and is faced with the decision of making the bike look as good as it should, or having to steal an old couch from the nursing home to make it authentic.

Authenticity is exactly what it is......not what somebody else thinks would look better.....it is what it is. a lovely piece of motorcycling history.

How do you stop with that front brake cable?

Ah, how the memories fade. Brakes? What fuggin' brakes? We didn't have brakes in the seventies just a lever on the handlebars that when pulled resulted in blood-curdling screams from the rider followed by the thud as bike and rider hit a tree/rock/etc.

<that the cable wasn't connected had been pointed out by others  >
