1978 Kawasaki KX 250 A4
1978 Kawasaki KX 250 A4. I’ve been told less than 1500 were sold worldwide.
Project complete in 2004.
Bike has been set up and used for vintage racing in the evolution class. It has been
completely rebuilt mechanically. All new reproduction plastic and seat cover. The
frame, pipe, and gas tank have not been repainted.
Engine:  New rod kit, main bearings, seals, and fresh bore ( 1st over), Wiesco
piston. Cylinder was previously sleeved. New reeds. Stock pipe with Pro circuit
silencer.
The bike was missing the rear fender, 1 side panel, and the seat cover was homemade.
It was mostly original but very rough condition. The front tire and handle bars were
the original parts. The engine was ran with no air filter and required a complete
rebuild.
Chassis:  Currently has 1979 KX 125 fork and swing arm installed for longer travel.
New swing arm bearings and seals, new fork seals. Custom built Works Performance
shocks with triple rate springs and 5/8" shafts. Renthal aluminum handle bar. Cables,
chain/ sprockets, air filter, and tires were all replaced.
