Thanks mate, glad you liked the video and thanks for sharing your experience with the Z900. We have plenty more new bike, classic bike and rider stories videos on the channel if you are interested.
I had a 1976 KZ900, a brown one, which was the only color other than green available that year, and it was a beast! The only complaint was with the frame's tendency to flex and get "squirrelly at high speeds (105mph and above). I still have the sales receipt, $2609.00 US. Be careful out there. Seeya! ☮✌
@@BikerTorque I totalled it in 1981,sadly. It took a little while to get back on the bronc again, but I did, on 77 Harley Lowrider. I've owned several bikes since, but none as quick as the 900!
One thing I love is how Kawasaki spent more time in the styling, instead of being about basic functionality. Even coming towards the late 80‘s they were pricey which made me opt back then for a more affordable Suzuki Gs1000s. Thanks for taking us pillion down memory lane, Best wishes from Germany

@@BikerTorque 👊GS Going well…would have been great to join you for Tassie but not to be unfortunately. Look forward to hearing about that adventure and many others in between. Love the channel and looking forward to the next installment. Look after yourself.
Great review mate! I remember drooling over these in centerfold ads in Cycle magazines in the mid-70's when I wasn't even old enough to drive yet. I finally bought a '74 Z-1A in my graduation year of 1979, and I still have it to this very day. IMO, there has never been a nicer, better built motorcycle ever conceived. Mine has been upgraded with disc brakes front and back from a '78 KZ 1000, and it has an engine from a 1980 KZ 1000 that has NEVER ever been rebuilt, with electronic ign, a Kerker pipe, and 29mm smoothbores. However this winter it's getting a piston kit, and only because the valve seals are causing the engine to smoke a bit, so why not do a total top end rebuild? . The bike is green with gold stripes and I can't go anywhere with it that people aren't turning their heads, or yelling out open windows or from sidewalks, or walking up on me when I stop just about anywhere. Owning and riding it never gets old, even though I'm a 62yo man on a 50yo motorcycle. It's simply heaven in motorcycle form & a real-life time machine!. Btw, many of my buddies who also had them in the old days still have them. Kawasaki Lets The Good Times Roll!
Thanks, glad you like the video and thanks for the info on your bike. Definitely up there with my favouite bikes of the 1970s, although if Im honest the bike I really lust after from the 1970s is a Daytona Orange BMW R90S, one day I'll get one, but would love a Kwaka in the garage also.
@@Jedders1968 Thanks bro, I'm just getting her ready for the road now. Just light duty stuff like oil change, chain adjustment, tire pressure check & overall check up.
I own a Z1000 A2, changed the carbs (Mikuni RS34), shock absorbers (koni), swing arm (krüger & junginger), exhaust 4 in1 (Schüle). Now I have a "new", really fast and good looking bike. Will never sell it.
Great video! I'm lucky enough to have a Z1 (1973) and a Z1B (1975). I've got other bikes but these are just fantastic .... I can't get enough of them. Just need some decent weather! 🇬🇧 👍
@@BikerTorque The Z1 has twin front discs which was an option at the time but I had the second disc fitted - it is a good upgrade. I try to alternate taking them out on dry days. I use the Esso 99 fuel in them and they run much better on this imo. They don't like not being used and need a good blast at least once a month. The Z1 is the Orange and Brown colour and the Z1B is Candy Blue. The Z1 has a black engine and the Z1B has a silver engine. I can't detect any difference in power. The Z1B has had 3 of the spark plug holes helicoiled (before I owned it) and the 4th one blew the spark plug out on a recent ride so that is now helicoiled too. This might indicate a potential weakness with the aluminium head but the Z1 is still standard and no problems to date. PS I've also got a 1985 Kawasaki GPz 750 Turbo which is a mad bike! 😄👍
@@BikerTorque I liked to play with cars on I-90, I’d be behind a car driving 75 at an interchange, accelerate down the off ramp, make a full stop, then blast up the on ramp and come out ahead of them.
In America we all got a Kerner header and upgraded to dual disk in the front. Never paid attention to how many miles on it only that it was well taken care of in good running condition. Nobody had a leaky bike that's not true. The brakes and everything about the bike wreck just fine back then they were as good as it gets. Today people totally describe the bikes half correct and half wrong. Super easy to work on. I owned 4 and a 1980 z1r 1000. I'm 64 I'd say I have enough experience back in the day to say today I'd rather have a newer bike.
We are heading down there next month, but not on the old bikes unfortunately. The Laverda is having a few engine issues, and the Z1 has a few issues that need sorting with the carbs, so it’s modern bikes for the trip this time.
@@BikerTorque This is the best review of this type of bike yet. Thank you for being a fellow gearhead and getting all of the points. Love it that you gave us all the first gear thunk. I adore that about my other 4 cyl bikes of this era. Lovely bike
Kawasaki made some quick bikes in the 70’s and 80’s. Also it is easier to get parts for the 70’s models as they are well supported. You looked like you had a ball on the big zed.
Riding old bikes is like playing an old Fender Stratocaster, sure there are newer faster and better bikes, guitars. But they do they job well, right? I don't see the need to cruise more than 50 - 100 km/h down a road. I'd feel a bit unsafe at high speeds, then I'll use a car. It's the beauty of the ride, not the speed nor the cost. In my opinion. 😊 PS. I have an old stratocaster, not old enough for museum, but it's old enough not to have poly coating. 😋
I have a 1976 kz900 z1 frame code. I rode 200 miles on it today!!!!! No fucking shit great bike, she is my blue bitch. I've had her of 20,30 years. I cant get over how smooooooth that air cooled motor runs. Don't forget Marvel Mystery oil for air cooled motors. Thanks for the video.😆
I have 75’ Z1b in the garage. New bike are faster but back in the day nothing was faster. Speaking of fast, 120 mph is way off. I’ve personally had mine rung out to 145 mph (indicated). Wouldn’t exactly trust Speedo accuracy. None the less I go to cars and coffee and draw attention, I ride the Z1. The modern Ninjas are a dime dozen. Not going sell mine till I got one foot in the grave.
Hmm... I don't believe it was ever known as a KZ900 in Australia. 🤔 KZ was an American model designation. Here in Oz it was known as Z1A, Z1B, Z900 or Z1000.
@@BikerTorque KZ900 was for the North American market only and had a single front disc brake. In Australia and the UK, they are called Z900 and have twin front discs as standard. The UK version had a longer rear mudguard. The Australian Z900 had the same short mudguard as the US version.

Hey John, thanks for checking out the video. Yes 1970s brakes aren’t a match for the modern stuff, but agree it’s a bullet proof engine. Good to hear from another Sydney-sider. Might see you on the road some time.
"Excellent handling", your kidding! They were / are terrible handling in stock form. I was there when they were released. I followed a mate up the Beach Forest road with this girl on the back, watching the bike flexing all over the place.
I have to say one I had handled pretty well, might have have a suspension upgrade, can’t confirm.l but most press for back in the 70s seemed to have a pretty high opinion of the bike, from what I found. I can’t confirm, as I was only 3 in 1976 and therefor didn’t have a full licence. Thanks for wTchingy
@@BikerTorque There's a reason they were not put on as standard..... because they are hideous..... and totally spoil the look of an otherwise great motorcycle!
"It's like a zed-1 only better". Obviously they know nothing about performance. Go to any drag strip and look at how many z-1 engines are still being used. This will easily tell you which is better. For decades it was what every other manufacturer attempted to compare to.
Dude it’s the same engine. And there wasn’t that much difference between any of them. Have a z1 and want a bigger motor? Put a 1015 or 1165 head on it. Carbs cams clutches cranks. It was like legos for bikes, parts everywhere and basically all interchangeable. But as far as the z1 vs kz900 it’s the same exact motor except maybe a couple of tuning differences
