In 1986 I bought a quad from Team Yamaha in Santa Anna Ca. It was built from a 85 ATC250R and has a 85 Tri-Z 250R engine. I was told it was built by them for the 85 stadium season before Yamaha had a factory Quad. At the time it was featured in a Dirt Bike Mag. ( I think) they had showed me a copy. I'm now in the middle of restoring it and need help identifing the front end, plastics, swing arm, axles and sprocket ect. If you know of this team hybred or had the old mags please help.

 

Sorry, I can't help you, but I would LOVE to see pictures of it. Sounds really neat. Is there anyway you could post some on your page?

 

love to see em too.
