My fling at a motorcycle was turning an old Kawasaki 350 Bighorn into a psuedo cafe racer. Completely rebuilt the frame with clip on bars and an engine that was used to flat track race till the new best engine was the Honda 500 thumper. No top end but 0-60 was holy s-word fast. Gearhead buddy had a Denco prepared H3 tripple. I didn't have the testicular fortitude to ride that monster. Of course my buddy had more balls than brains.

Got lots of friends with limps, funny shaped arms and sorts of dissabilities from not being able to handle the fierce powerband on those .

I clearly don’t have the experience ( or capacity) to understand very much of it, but it’s an honor to listen in, great conversation!

The H3 was kawasakki with a fierce power band that kicked in a instant so you would be tootleing along in traffic at 40 mph with the engine putting out 15Hp .
The traffic opens up a bit , so you accelerate , but the slight movement of the throttle raises the revs to where the power band kicks in and you instantantly go from 15Hp to 45Hp
The front wheel points skyward and the bike ends up enbedded 2' into the boot of the car that was 200 yards in front of you before you moved the throttle.

And to that my buddy's H3 was race prepped by a company called Denco. The engine is a 750cc 3 cylinder 2 stroke that stock was pretty much the fastest bike around. His Denco H3 could bury the 150mph speedometer with ease. Bert is right about the powerband is like an on off switch 10hp or 100hp. Not much in between. The Kaw H1 H2 and H3 were called the widowmakers and many insurance companies would not insure them. In the 70's kaw tripples were the fastest stock bikes 0-60 and 0-100. Unfortunately they also had 70's front fork design and geometery. Things went from a straight line to dead real quick.

Same story down here
By the time the H3 was released the insurance premium was near the cost of the bike
But to race production class kawaasaki had to sell 200 each season so there were a lot of really good deals if you had quick reflexes and a death wish.
I rode BSA's ( still do ) so lightening fast throttle response was not my biggest worry on the road .

After my second time i got put in the ditch by a stupid car driver i stopped riding. Walked away from the first one. Second one i limped away. Ground the toes off my boots, the knees out of the jeans and ruined a nice Bell Tourstar helmet.

better to ruin a helmet than what's underneath it.

Oh yeah. I slid a pretty good way face down then went under a guard rail and wound up in ditch full of water. The handlebars hung on the guardrail and kept the bike from following me in the ditch.
