Had this brought to me to give it a going over.

I'm guessing about 1990, but I'm no Beta expert.

What does anyone elser think.

Looks like a 92 or 93 Zero

That is a 1990 Beta zero, it was the very first one. I saw it for the first time at the first trial that I ever saw, the 1990 world round, held by the Canada Pacific Trials Club (CPTA) at Ioco British Columbia. That event and this bike helped create my addiction to trials. The zero was so trick for its time, blew my mind! The red and silver zero of 1990 was followed by a black,silver and green stickered model in 1991, gold framed, purple and yellow graphiced 1992 and finally the silver framed with red white and blue graphiced "gara-trial" model(still technically a zero) model in 1993. The techno model began in 1994 and thats all from me! Cheers, G

Thanks guy's.

Now to hunt for the parts needed for the refurb.

I have the PDF parts diagram on my website which could be help to you.

Wiring diagram would be good, Thanks

Check the swinging arm carefully, around the top/bottom of where the bearings fit.

They were prone to cracking along there.

I had a 91 (black and green) a few years ago that I bought in boxes and had to rebuild.

Lampkins helped me with quite a few parts.

watch out for water pump issues with this engine, you will have to split the cases to fix it...
