1972 Kawasaki 750 H2


In relative phrases, it wasn’t so way back that it was considerably uncommon to see bikes on the highways and byways of center America. Principally, they had been quirky oil-dripping British bikes or nefarious “love ’em or hate ’em” Harley-Davidsons. The reality is, Nineteen Sixties America was automobile loopy.

The tide started to show, nevertheless, within the late ’60s when the avalanche of Japanese manufacturing expertise hit America’s shores. Child boomers had abruptly develop into a significant buying pressure and motor autos advanced from sensible and utilitarian to enjoyable and thrilling. In motorbike phrases, everyone knows what occurred: four-cylinder overhead cam bikes from Honda abruptly turned the brand new world customary for efficiency and reliability. And it quickly turned obvious that Honda wasn’t going to be the one participant. Different producers threw their hats into the ring, re-purposing plane and army manufacturing services to assist quench America’s thirst for pace, enjoyable, and journey.

Whereas Honda promised to offer the inconceivable trifecta of pace, affordability and reliability, it turned evident that the model was going to be constructed on the latter.

Amongst Rick’s in depth assortment of triple memorabilia had been authentic rolls of 21/4″ colour transparencies taken in 1972, that includes a gentleman named Tony Nicosia aboard an early H2 750 at Orange County Worldwide Raceway in California.

The success of the N100 Plan closely revolved round Tony Nicosia, the diminutive ex-USAF serviceman who discovered himself in Japan within the early ’60s and was spending quite a lot of time at native racetracks and drag strips. At 5’5″ and 102 lbs, Tony was the proper specimen for motorbike drag racing. Add to {that a} penchant for pace, excellent engine-building abilities and the center of a lion, and Kawasaki had their quarterback for N100. By the point he retired from Kawasaki in 1973, Tony had set some 120 drag racing information and the Kawasaki model had develop into synonymous with pace—a mantle it continues to put on to at the present time.


In a considerably theatrical reside demonstration in 1969, Kawasaki technicians uncrated and assembled a brand-new three-cylinder H1 two-stroke 500 cc bike at Lion’s Drag strip in southern California. The press watched with bated breath as fluids had been added; with a prod of the kicker, the beast crackled to life. Tony Nicosia piloted the machine to a 12.96 quarter mile at over 100 mph, and the five hundred triple was formally the quickest manufacturing motorbike on the planet.

Three years later, on March 11, 1972, Tony Nicosia, using the H2, a 750 two-stroke triple, set a manufacturing bike quarter mile file of 11.95 seconds at 115.38 mph at Fremont Dragstrip in California.

Though the Kawasaki model has remained on the prime of the efficiency charts for almost 5 many years, names like Tony Nicosia and people unbelievable information set on America’s drag strips of the ’60s and ’70s have slowly pale from reminiscence.
