My first REAL dirt bike. Nothing like it has been made since. It has the most Peaky power band ever for a 125. This power band wasn't the best for racing but back in 76 nothing could keep up with it.
I had one just like it, except the forks on mine had a cast in rib front and rear on the lower part of the fork. Must have been for strength ? Never seen another like it. My budy had the same bike and year but his didn't have it ???
@@JSmith19858 I gained almost 40lbs since my last 250cc bike (97 KX250), and raced at about 180. I am not sure if my newer, stock 2019 YZ250 is the slowest bike 250cc MX I ever had, (and the jetting is still stock rich.), or my added weight is the biggest difference. So I will say, that little vintage 125 hauls you around pretty good.
@@EarthSurferUSA I've lost 15+lbs since this video, as I could start exercising again once Covid restrictions had been lifted. Got about the same still left to lose.
We certainly did plenty of work to it. The only original unmodified bits left are the wheel hubs and fork sliders. I might make a video when it needs a top end refresh showing the internal mods.
@@JSmith19858 I remember the canister forks were called "the "Speedo and tach forks" because they resembled a speedometer and tachometer. I am not sure they were full air forks though, as I think they may have had springs in the legs also. Nice bike.

I had a ‘77 that I bought used in ‘78 for$400. Rode it a while and traded it for an RD400. Best deal I ever made.
I too had a 77 yz. Loved the luminum fuel tank. Rear shock was awesome, but needing adjustments.
I had a 1978 YZ80, it was so freaking awesome! First time I hit the power band, I was in love!
One of THE best looking MX bikes ever made.
I was surprised how good it sounded, crisp and on-point..
Just by hearing it I can tell that old bike has some power🤤🤤🤤
Yyxys ysudhehhdhdudhrhheh
I had that same yz. Good bike
my 81 cr 80 spunded just like that love the old air cooled bikes
He's way too big for that little 125, she's a lovely old girl though 🔥
They're pretty small in comparison to modern

Awesome motoX!!!
I had the same bike only 100cc
The 100 was same size as the 125s i believe?
Sounds fast
Nice
nice old yammie
You look to be a bit on the large size to be riding a 125...you need a big bore
We have a YZ465. The 125 was something a little softer for my father to ride as he's 71.

@@JSmith19858these were the same size bike as the yz100 correct? Really just motor differences?
I thought the 1976 had the air canisters on the top of the forks.
There's a half year model. Early '76 has conventional forks, late '76 air forks.
The air forks came on the YZ125X conventional forks YZ125C both 1976 models

No idea. We would be happy if it made 25hp. It's more powerful than the standard bike, and that's 20-21hp.

I had a cr125 would burn this off
Good for you, buttercup.
you HAD, he HAS.
And? I'm building a CR500 that'll have around 90-100hp. Just enjoy the bike you bitch
I had 74 CR 125 that in 76 was getting smoked by the Yz125's. They had much more top end than the Hondas. Plus better suspension.
@@ronpage101 I can't remember what year the name changed to CR, (maybe 1978?), but I know the 74-76 was the Elsinore.
