Hope you like the color yellow

Work of art!

The 74 tank has a green stripe on the tank

Awesome

All 125's ?

The CZ 125 in 73 was, bar none, the slowest heaviest 125 built. A slug.

Love it !!! ❤❤❤

Owned that exact bike ling ago Set it up for trail bike riding - brilliant motor , very light able to flick over logs etc - infact doing this iwas just the best - felt way lighter than a 2005 kx125 i owned In the top 3 best dirt bikes ive ever owned

Best looking bike IMO

Awesome!!!

Had a 81 loved it

This bike , or the 1981 model which was exactly the same apart from the decals , was the game changer that started the trend of major development in the world of motocross. Radical styling for the time , great suspension and liquid cooled. This bike absolutely dominated the 125 classes in 81 and 82 , nothing came close.

I had that very same bike. It was a ripper!

Wow, you showed the ultimate unicorn. Puch 250cc !! Man that is soooo rare !

Wait, it’s 3d printed? (Sounds like an old guy with a new term). 3d printed?

That bike in '82 was the best!! I had a '82 CR125R; great bike, but the RM had an edge.

The hubs are dead giveaway on Maco's

Bad ass dude 👍🏻💯

Maico

Ok well this actually didn’t answer the question at all. For height do you measure to the bottom of the bar end or the top? Or the center? Thats an inch in difference. Also to be really accurate do you measure to the ID or OD? Why can I not find this information!!??

Sweet Bike

Enjoyed my 81 and 82 .. Made a Regular kid feel as Factory as possible.. Great memories of my RM day's 💪👏✌️

I like the big fins on the head to cool it off.

Leaning up against the side of a home in 88 a never raced 82 rm125z stock with trick air box & alum adj floater struts brought home fired up shifted 6 gears fog trail behind it rt crank seal needed,3 moves later 2014 missing the bottom end in box,have a cheater roost factory ported 82 cylinder obtained rebuilt 81 125n bottom end have 81 stock top end read 81 had harder hit probably get rid of it 82 shock better then 81 of course will need rebuilt an chassis paint,seat cover plastic fenders,side panels & tank restored,rims&spokes are straight Floater rear end walked away from the competition in the day.

Still have an 83 RM 125 and will never let it go cheers 👍👊😎🇨🇦

Took mine to pismo dunes earlier this year, it wasn’t running right (or maybe it was me) so I only took it for 3 spins, she was pretty great though!

I had one of these I bought gently used in 83. Loved the rear suspension and handling. Great bike. Couldve used a bit more power though.

Very nice! I especially like early '80s bikes, it is when I became interested in them and started riding. I am curious about the welding you did on the rims. I have done that, too. Looked OK, soon cracked next to weld. I had assumed that they were probably weldable 6061. Mine were not...after some research found that most are 2024. DID and Takasago typically are, anyway. It is considered unweldable. They are ERW welded from new- electric resistance welding. Which works OK, I guess, but that is where they Crack for me. My TIG welds did not last. 2024 is very strong, but crap for welding. Al/Cu crystals don't form or distribute correctly during cooling. (?) Most aircraft sheet metal (wing & fuselage skin, etc) is this alloy. Sun rims are 6061. Any thoughts? Do you know your alloy? Are welds holding up? Mine re-cracked after one rocky, brutal eastern PA woods ride. Nice that you do your own machining and welding. I do, too. If you can't do all that, you're a parts replacer! Forming a squish area in that combustion chamber is something many people wouldn't think about. Beautiful bike, thanks for the video.

The 82 RM125 was a revolutionary bike when it came out. Water cooled with one of the first rising rate suspensions in a production bike. A true classic.

Bought one of these in 86, with a view to race. but sadly that didn't happen as the person that was going to be taking me, let me down and at the time i only have a motorcycle on the road. brilliant bikes.

40 + years old or not, you can still recognize the benefits of that sweet, sweet Full Floater system. I used it on both my '83 RM 80 and my '85 RM 125 and the way it feels trumps all else of that particular era. Its design of allowing the shock to work independently of both the frame and swingarm and has a very distinct and smooth feel unlike anything else I ever rode.

The 1981s used the “Power Reed” design that had a piston port intake with a 2 petal reed in the bottom of the intake port. The 82 used the “Full Reed” like is used on most engines and then in 1983 they went back to the 1981 cylinder.

One tooth bigger back sprocket

The Rm250z 1982 perhaps the fastest vicious motor and handled. These RMs dominated MX until 1983 Honda finally got it's act together. RM 500 was nice I raced . Smooth handled well never broke down much . Rear suspension was best .

I was 14 in 1981 and had a 74 Honda XR75 my parents had bought me when I was 11 for $200 and I learned to ride and work on it, but it was not much to ride anymore. I had all the magazines and was bugging my dad to let me get a RM/CR/KX/YZ 80 as I had been on a few and was 2 stroke hooked, He seemed to be for it, but kept stalling me, Finally one day he said how about a 125, I think you will outgrow an 80 too quick, I already knew the RM was every magazines top 125 in 81, and my favorite as well, so as soon as the 1982 RM125Z came out and was the best bike again, We got in the truck one day and drove to a nearby City that had dealers with more Motocross race bikes in stock than our little dealers had motorcycles. $1550.00 and it was in the back of the truck coming home. That bike was so good, and so unbelievably cool back then, I even got a Simpson model 52 full face helmet, Scott goggles and gloves. I was the shit....Although I have had several bikes since then, that is the only bike I ever bought brand new. Good memories for sure.

Great ride!!

Bike is absolutely mint!

Nice job great looking bike

Reminds me of the best times of my childhood

Un vrai vélo pas très puissant mais un moteur facile seul point négatif la boîte.

The first yz looks like a yz 100. Had a 83 yz 100

O had a 83 RM 500, literally bought the bike ripped apart in boxes and milk crates. Rider restored the whole bike. Painted the frame to match the Suzuki blue seat cover

Those full floaters were real handlers. I had the 465 back in the day I'd give my eye teeth for another one.

Had a Totaly fast 81 Won everything.

Mark "the bomber" Barnett would be happy with this bike.

F U C K E N AWESOME!!!!!!!

Way cool .

I wanted that bike so bad back in 82 !

I had a 1983 in 83 loved that bike super great bike. Wish I still had it

HELLUVA BIKE in its day!!!!!!!!!!!!!!!!!! RAIL CORNERS LIKE A PRO!!!
