1969 Kawasaki 500 H1
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. Even 16-year-old children might afford vehicles and fuel was virtually free.

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

Whereas Honda promised to offer the not possible trifecta of pace, affordability and reliability, it grew to become evident that the model was going to be constructed on the latter. Kawasaki, alternatively, put pace on the prime of its record.

This company objective noticed the launch of the N100 Plan:

The objective of Kawasaki engineering within the N100 Plan was to create a large-bore, quick bike engine for entry into the American market, the most important marketplace for bikes. Honda had already launched its profitable Honda CB450 in 1965 and Kawasaki desired to enter that giant bore area of interest.

The N100 Plan known as for an air-cooled customary bike with an engine capability of 500 cubic centimeters. The facility output was set at a minimum of 60 ps (equal to a per liter horsepower of 120 ps). The efficiency minimal was to make a 13-second standing begin 1/4 mile run (0-400 meters) (Wikipedia)

The bikes born out of the N100 Plan dwell on in the present day within the fingers of collectors, fans and 50-somethings reliving the times of their youth. The main pressure behind the cult following of the Kawasaki triple bikes is Rick Brett, an Englishman who now calls northern Michigan residence.

Amongst Rick’s in depth assortment of triple memorabilia had been authentic rolls of 21/4″ shade transparencies taken in 1972, that includes a gentleman named Tony Nicosia aboard an early H2 750 at Orange County Worldwide Raceway in California. Rick had bought the movie instantly from Tony and it was moderately obvious that the photographs had by no means been revealed. This was a discovered treasure for the Kawasaki triple and bike group alike.

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 numerous time at native racetracks and drag strips. At 5’5″ and 102 lbs, Tony was the right specimen for bike drag racing. Add to {that a} penchant for pace, excellent engine-building expertise 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 data and the Kawasaki model had develop into synonymous with pace—a mantle it continues to put on to today.


In a considerably theatrical dwell 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 bike on the planet.

Three years later, on March 11, 1972, Tony Nicosia, driving the H2, a 750 two-stroke triple, set a manufacturing bike quarter mile report 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 a long time, names like Tony Nicosia and people unimaginable data set on America’s drag strips of the ’60s and ’70s have slowly pale from reminiscence.

It’s a superb factor we now have pictures to remind us.
