HISTORY

In ‘77 the YZ125 had so much horsepower and mid-range torque, that the motorcycle racing press agreed it could out-pull, out-handle and out-win just about anything in its class.

Well for 1978 it came packed in the same kind of frame you usually only see on factory team racing bikes: chrome-moly steel. With thin-wall chrome-moly you get more strength for less weight. But the frame is just the beginning of the handling package. The box-section aluminum swing arm is longer than before. This gives you the double benefit of greater rear wheel travel and accurate high-speed running. And since long travel suspension requires a chain tensioner, the new 125 got fitted with the latest.

For the engine, it cranked out even more horsepower and matched the close ratio 6-speed transmission to the power band. With a compact power-plant in a tough new frame, the YZ125 weighs 6 pounds less than before. The 1978 YZ125 can handle anything you can dream up. When you know how they're built, you'll buy a Yamaha.

JTR

We ride, race, and restore vintage motocross bikes from the 1970s through the early 2000s. Every motorcycle we buy and sell is personally inspected, serviced, and vetted by us before it changes hands. My father, Chris Reed, has been racing and repairing these machines since they were new. He put me on a JR50 at four years old, and I've never stopped riding or racing. I later worked under Peter Boggia at Moto Borgotaro, helping service and restore some of the rarest motorcycles in the world.

When you purchase a motorcycle from JTR Moto, you’re not simply buying a bike. You’re investing in a passion shaped by three generations of racers with a dedication to preserving these incredible machines and the culture that made them special.
