HISTORY
The KX125 had genuinely usable power delivery.
This rotary valve air cooled 124cc 2 stroke engine put out a claimed 22hp @9750 rpm and had tons of low end power for a bike only weighing 178lbs.
Bottom end and mid-range are similiar to a CZ or Husky - except without the punch on top. Kayaba nitrogen shocks out back and stock suspension had 5 preload positions.
The KX is by no means a slow motorcycle. With good traction, it'll stay side by side with an RM, however put it on the track with bumps, holes and jumps, and it’s another story. The suspension was not exactly plush having gone unchanged from 1974. Although it may not have been the best handling bike for ‘76 you cannot deny the power of the KX.
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.
