Which KZ came stock with the most HP.

Just curious,which bike has the most HP.

The highest number claimed from the factory I remember seeing is 120 hp. Two different choices to get that, GPZ1100 or KZ1300.

Although technically speaking the 120 hp GPz is not a KZ, it's model designation is ZX 1100 A aka GPz 1100 UniTrak - last of the big GPz's to have the KZ designation is the 1982 GPz 1100 aka KZ 1100 B2 rated at 109 hp.

buttttttttttt...IMHO, those claimed 83 of the original 73-75 Z-1s were the best...you WERE on top of the heep back in those days even if those pesky Kaw triples (500 or 750) could give you a run over shorter distances.

look in dictionary under CLAIMED HP !:laugh: those are just numbers tossed out by factorys and magazines to sell bikes for the most part

Let me toss in my info too...like The Gringo stated, the KZ1300 had 120 claimed HP, but I'd like to add the 1984 KZ1100R1 (not officially seen in the US) which had a claimed 114 HP. The KZ1100R1 had a KZ designation but a ZX1100A motor

ill be looking for ya on the coast highway mr!i figure with my 12" height advantage on ya it should be really close.its rated at 3.5 at the rear wheel,so im guessing that means about 78 at the flywheel by factory/magazine standards but i read on the internet that if you put a rack of 34 cv's with a custom intake on there and a header it bumps it up to 4.7 at the rear wheel which im thinking means around 130 at the motor.i wasted all these years building big motors when all i needed to do was buy some magazines and cool stickers! :woohoo:

it would be great to see folks make it down or over ,or up,,,anyhow i would love to get a campground reserved at the track each year and make a ride rendezvues for a summer west coast kz get toghether....i checked and i can get a site for a good price that holds 8-11 folks,and i can get 99% of the gear to set up the site for folks...plus there is my place 5 minutes from the track to shower and recharge,and the beaches....i checked at this cool hotel on the sand by marina and they said yamaha books the entire place...bet with the cutbacks in staff,,,not so much now....peace....

In 77 I sent stock cams to Ken Harmon in Ca. for a reweld and regrind! Cheaper!
I had friends at the Chevy Tonawanda engine plant bore my
stock carbs out to 29mm, cause I seen somthing about this!
We hooked up 4 single ignition coils in line for both sides and used Blue Steak ignition points from a 4 cly. Chevy Luv.
With some cool silicone wires. Some nerd guy's technology?
We could still get some good Sunoco High Octane gas back then.
All I know is I burnt though 3 Nan-Kang 5.20 X 18 tires, with 10 pounds of air in the summer of 1977!
14 tooth countershaft sprocket and a 39 on the back!
Oh ya, I was the coolest with a chrome Kerker header.
No baffle of course!
Pulled the front wheel all the way thru 3rd gear!!!
I am over 50 now.
Still Wondering how I am still alive!
Just a little bit of Z street history!
We used to see who left the longest tire mark!
Not the longest wheelie!
Later

The 1976 version is far superior to all others. Even the earlier years....LOL...Russ

so does anyone know what my 84 zn1100 came with?
i thought i remembered reading it was a 102 hp bike since it's a gpz motor.
