1973 Kawasaki S1A


Here is my 1973 Kawasaki S1A . This is the early version of the S1 with the 32hp engine before Kawasaki de-tuned the engine to the later 28hp. Overall the bike is in great condition for its age with many parts replaced or restored to a high standard. It has been fitted with brand new Higgspeed expansion chambers which sound incredible. The bike has approx 12800 miles on but is being ridden when the weather allows. Engine and frame numbers are matching for the year of production which is confirmed by Kawasaki dating certification.

Airbox assembly repainted and new filter fitted
Front end rebuild - fork seals/ fork oil/ repainted fork ears/ new headlight (fork seals were leaking)
