So what's the most miles you have seen on an old Yamaha Enduro? This came up in a prior thread , and popular opinion said that this new thread should exist. Since I'm starting it, I get the liberty of setting the parameters

It must be a Yamaha Enduro bike, nothing designed for the street like an RD. I'm thinking it's fair to consider anything from 1968-1973 "first generation" as the bottom ends are essentially interchangeable. Maybe we should open it up to any of the dual shock models as they are not all that different?

This 1972 Yamaha AT2 125cc was purchased by me on July 28th, 2020 in Willows, California with 23,637.6 miles on it. Stickers on the oil tank and rear plate indicate it was originally sold in either Red Bluff or Chico, indicating it has lived it's life 45 miles from where it was sold. Seller told me the prior owner commuted to work on it in town for many years, and eventually gave it to him, title lost in a house fire. Guy who sold it to me did the terrible repaint.

My guess is you win!

As far as "generations", the 125/175 kept the same bottom end from 69-73... most of the other models inexplicably didn't... so I'd call "first generation" the badge bikes (68-71), the "second generation" the reed valves (72-73). But you're right... 68-73 models are more similar than different.

Then in 1974 most models got a complete redesign using "motocross" tech. That would be what I'd call "third generation" (74-76 in the USA... or on the less than 125cc models, 74 to 1980's and even to 1990's) The 74-on twin shocks are quite different in many ways than the earlier generations.

And of course then you get the to monoshocks in 1977 which would be 4th gen the way I count them...

And in the US, that's where it ends... other countries enjoyed more generations and often a lot more years of the earlier USA generation bikes... Like the AG series seems to be pretty much a USA "second generation" design but was sold for many years beyond 1973 in other countries.

Looking forward to hearing the stories!

Hey Darin, any idea if the engine was ever bored?

I'll take a look at it next time I get a chance, we've been spending time up in Mt Shasta to escape the heat so it went straight into the side yard without any inspection yet. It feels like good compression so I'm guessing it's been bored.

Good summary Mark!

Looking forward to some stories behind other high mileage bikes

I agree completely on the “generations” From Mark T as that is how I delineate them. That makes me have one from each generation!

Ok that's a good trick Mark, I wasn't going to touch it until late winter but had to check on the bore, and now a few parts are in the mail. Short story is it's 1st over, long winded reply feels like it should go with the original post here.

Lot of enduros come and gone here at my place, but THEE highest mileage Japanese enduro I've ever purchased isn't even close to your AT2. Had to pull out the external hard drive to find this pic, but see it and...not near as high as that AT2. Still, pretty high miles, and this bike was NOTHING but problems, and it was promptly sold.

Not the original instrument to this 1968 DT1 but from another 1968 DT1. I bought this from the original owner's widow who's Husband was going to restore it but he passed away before he could really get started on it. It's the highest mileage I had seen on one of these prior to this thread.


showing 15,603 at this time and I put well under one thousand miles on it, likely 500 ish miles since I had it on this bike.

Is this the one you sold.

When the new owner picked up my DT1C, there were 15774 miles on the ODO. It had a 3rd over piston installed in 2008.
