Twin Shock

What ever you can get it for $450 or less.That looks like a low hour bike.

Actually Yamaha first introduced the DT 125 in 1974, the prior 125cc Enduro models were AT. Their production ran from 1969-1973.

You need the wing nut you highlighted.

Yes, the european version. Not sure how many countries got the low fender version.

I agree.

Looks like a JT2, 1972 Yamaha Mini Enduro 60cc

Try posting the picture again, I don't see one.

It's your call on the reed assembly.If you are doing a proper restoration change it back to piston port. But make sure you do connect the carburator to an air filter some how.

You can put the front end on your bike, just remove the triple tee and install it into your steering neck. I am using a MX 360 front end on my 125 and 175.In other words the whole front assembly.

I certainly like mine,When you dial in the suspension and change the tires you can fly off road. The bike is very respectable on the street as well.Makes max power about 10,000 rpm.

Here is the U.S.the WR 25OR is the only one of the group legal for operation on public roads. I have one and love it. The original tires on the bike are more suited for road use.

Yes,that bike is pretty rough.I think it is just a parts bike.Would be for me anyway.

Yes.

Here is your answer.

First year GT80, looks to be a good one.

There is no such model, You probably have a 1974. The CDI from a 1974/75 models will work only. You might just want to go with a new PVL Ignition. Even if you find replacement parts they are still old.

You can find the airbox on E BAY often. The 74 and 75 MX125 and MX 175 use the same air box.You will see the inner rear fender and the air box riveted to it.

$500 To $800. 1976 YZ 125C and YZ 125X were first year monoshocks. The 76 C was introduced in 1975 but was a 76 model.

I think you have a YZ 80 F.

The 1975 YZ 125 was a Twinshock, the 250 and 360 were first year monoshock bikes.The only differnce in the 74 and 75 YZ 125 is the color.

The stock front rim is 21 inches. Rare bike, keep it or sell it to me.

Make it look like one, parts on on EBAY.

The color is crystal silver.
