1975 Kawasaki S3 Mach II

Back in the time before 4-strokes dominated the internal-combustion landscape, Kawasaki produced a variety of 2-stroke street machines. Better known were the 500cc H1 Mach III and 750cc H2 Mach IV 2-strokers, but the 400cc air-cooled Triple of the S3 Mach II is sweet in a tamer sort of way. Produced for only two years, 1974-1975, the S3 is far from common, and the one seen here appears to be in decent condition with less than 14,000 miles on the clock. It looks to have been somewhat cafe racerized, so the Buy It Now price of $1,900 seems a little steep. But the latest bid as of publication was only $500. Could be yours.
