I hate to think what the rpm's to do 100 in first does to the engine's life expectancy.
I used to ride and for several years owned the street legal version of a very hot 350cc two-stroke that at the time was kicking other bikes up to 900cc on the racing circuit.
One day on a nearly deserted interstate out in the desert a CHP bike officer pulled next to me and mouthed "Is that thing as fast as they claim? Lets see how it compares to mine." Then he upped his speed and pulled ahead of me, I did the same - repeat about 4 times and we are going way faster than a sensible person would want to (I was a mid-20s Vietnam vet and a touch nuts at times.*) when he mouthed "That's it for mine." I grinned, pointed to the clutch and held up three fingers to show I was only in third of five gears. Then I popped it into forth and fifth as I pulled away from him. After about a mile I slowed down to legal speed while he caught up to me and just looked at my bike with a big grin on his face, shook his head and waved goodbye as I took the next off ramp to turn around and go home.
*When I got stressed etc. I would go on the interstate/freeway and chase trucks or fast moving cars to force myself to concentrate and forget what was stressing me out. Then I would get off the freeway and make my way towards home on surface streets exploring areas I had never been to. It worked, and I lived through it. A few years later I traded for a 750cc cruiser with full fairing CB radio and stereo, saddle bags etc. and used it to just cruise around for fun or go to work if my regular ride was in the shop. I had a spot right next to my classroom they let me park it so I could watch it and keep students from playing with it.
One night I was just cruising at about 60 on the way to a friend's house westbound on the I-210 coming up to Pasadena with classical music blaring when a big Mercedes that was passing me in the fast lane suddenly slowed and dropped back even with me. The passenger window dropped a few inches and I saw a woman's ear up to the opening, then she turned to the driver and was pointing at me and shaking her head yes. Astonished that the biker in combat boots, jeans and an Army field jacket was listening to Mozart. I smiled, waved and took my off ramp.
I gave the bike to charity Dec 2019 and now my only ride is a comfortable mid-sized SUV.
I hate to think what the rpm's to do 100 in first ... (
show quote)
The Gen 1 ZX10R pictured on page ten, redlines at 13,000 RPM, the rev limiter kicks in about 200 RPM later.
So it actually does about 200 RPM more than 161kmh (100mph) in first.
13000 RPM does not impact engine life per se.
The machine is a homologation model for the World Superbike Championship.
With the race ECU the redline is 14,000 RPM.
In any one track day, the engine goes past 13,000 RPM hundreds of times.
They are an astoundingly reliable motorcycle... as long as they have
the proper maintenance conducted by skilled and caring hands... coming from a company
that makes space craft, it's not too surprising.
I'd done over 60,000km on the one on page ten (when it was running
at least as well as it was when new) when I had the back of the bike pass
the front of the bike and wrote it off... oops!
3 contributing factors to that off:
1.The road had been damaged by trucks.
2. Had changed to a less soft compound rear tyre... not as much traction as the previous rear tyre at that temperature.
3. Pilot error... shoulda' used less right wrist.
I've replaced the ZX10R with a ZX12R... an extra 200 cubes
with a more civilized engine tune and more leg room... more fitting for a 65yo man like yours truly.

sprockets is reached in 5th gear (in 19 seconds from stationary) with one more gear still up your sleeve.

Having said that, I wish I had one in the hanger.
Below's a nicely restored and lightly modified one I photographed earlier in the year:
