1973 kawasaki z1 – top speed

Ever since getting my Z1, I’m pretty obsessed with them.

If you didn’t know, the Z1 was basically the hayabusa of the 70’s.
Pretty sure it was the fastest bike until the early 80’s.
And, it was definitely the preferred pro drag race bike for a long ass time.

Apparently, the bike does 140mph in stock form.
I’ve only done 110 on mine so far.

In 73, they broke a record doing 160mph on a basically stock Z1.
Pretty badass.

Watch these two videos from 1973.
Z1’s with clubman bars at Daytona breaking records.

I found this out there and couldn’t help but post it.
Rednecks get a Z1 running. Laugh my ass off watching this.
I love how the camera man yells at the z1 once they get it fired up. Ha.


I picked up a new seat for my Z1.
It’s basically the stock seat cut with a cafe dip in it.
Brand new seat pan, foam, and cover. All assembled, ready to bolt on. $160.
It’s from Z1parts.

    The rednecks z1 has some nice upgraded mags and dual disc front and disc on the rear from a later Ltd model they don’t realize it’s only running on 3 cylinders. On the pilot jets from idle to about 2500 rpm then it goes off of the main jets were the bike sounds like a it’s running on all four cylinders then they need a longer drive way as there stuck in just first gear

My 500 has been running pretty solid, but over the last few weeks I’ve been fine tuning it. I pulled the carbs last week and did a bench sync, which helped a lot. This morning I did a full tune up and then decided to take her out for a ride. I was on my […]
