I bought a brand new 1972 (first year) model left-over for $1200 from Champion Cycle on Western and Addison Streets in Chicago. Talk about bang for the buck. I was a school teacher at the time and used to commute to Oak Park weather permitting. Always a fun trip.
These bikes were lightweight for the time. The 3 cylinder exhaust note was unique and it also had a big intake howl as well. The vibrations were unique too. Unlike my '69 500 which had a drum front brake you could fade with a fast trip around the block, the H2 would stop. The handling was uninspiring, but who went around corners fast in those days anyway? I installed a steering damper, .......the only bike I've ever had a damper on. As I recall, Kawasaki had a bracket on the bike you could mount a damper to.
When you rode two up and rolled on the throttle in first gear, the front end would slowly rise off the pavement as the power came on. This was amazing at the time. Can you say high center of gravity? I had flat bars on mine.......very progressive in an era before the sportbike.
I once took mine up to 120 mph "indicated", got skeered, and never went that fast again for many years. I think the power peak was about 7000 rpm, but that was before even the cycle mags had dyno reports. I have no idea how much rwhp the bike made or how fast it would actually go.
I raced mine at Great Lakes Dragaway in Union Grove Wi, but never did very well. The bike was very intimidating and would wheelie at the slightest provocation out of the hole. I was very inconsistant (unlike the big fours I raced) and I think low 13's was the best I ever did. I wish I could remember the mph because that would give a clue as to the horsepower. The bike just begged for wheelie bars. I did destroy a clutch trying to learn how to ride the beast on holeshots. That was the only clutch that ever broke up in pieces on any bike I've owned. Funny thing, I once saw a 750 triple rolling down Elston Ave in Chicago with wheelie bars, no doubt raised up for clearance. Quite a sight.
It was a fun bike. The four stroke guys used to laugh at us 2 stoke guys because of the sound and the smoke, but you can't help but wonder what would have happened if the Japanese had developed a liquid cooled 4 cylinder 2 stroke sportbike. One fast smokin' ring-ding!
I had the blue triple for a year and then bought a new '74 Z1 and believe me, it did everything better.
