1973 Kawasaki H1 500 Mach III 

I love the smell of Castrol in the morning

Had the H2 750 when I was 16. Huge handful. Still looking for one.

Power goes from being a 250 until you reach the power band then it's a beast. Quite a shock if you're not expecting it.

I'm OLD enough to remember when these bikes were selling new, and nothing was faster than these 2 stroke triple Kawasakis. They didn't handle great in the twisties but what a crotch-rocket going straight. Love that 2-stroke sound. I also LOVED the Yamaha RD400 another rocket. I love the rural New England countryside in your vids too, easy to spot by the classic building most of which I'm guessing are over 100 years old. My dad's roots are in New England though he left in 1942 to fight in the SW Pacific, and newer wanted to return there after exposure to the war. Sad how the classic New England accent is fading away due to exposure via TV and internet, no more isolation of small communities. Keep up the great videos. Aloha.

I bought a 1970 mach 3 in 1971 for $600.00 MSRP was $999.00. Rode it for a year in Texas and survived. Sold it to another Marine and flew home for good. It was my first and last motorcycle and I figured why press my luck. I always referred to it as a chainsaw on wheels but a lot of fun at 21.

My first street bike was the 1974 400 triple. I could hardly keep the front wheel down when shifting. All of my street bikes have been Kaws 400, 650, 1000, 1100, and still have my 77 kz900. The 400 was unbelievable fast and to this day have never rid anything as quick. I know they are rare but if you ever get the chance ride it you wont be disappointed

One of my dream bikes in the early 70s, when I was a teenager. Didn't get to own one, but did eventually own a Yamaha Rd 350 LC, a Kawasaki k1 250 and a Suzuki rg 500 gamma, all great 2 stroke motorcycles. We have lost so much in the name of progress.

Such a beautiful bike and a real classic!!! Love two stroke engines!

Love that sound,,Miss the days when I worked at local Kawi shop ,,Kawasaki East,,test ride the new h1//h2!!! Yee haw!!!

I had a friend let me borrow his 2 stroke once. I remember being sent to the back of the seat and barely holding onto the end of the throttle while it was wide open. I just kept shifting and slowly worked my way back onto the front of the seat where I could finally control the throttle. My face was directly over the speedometer and it was reading 110mph. It all happened so fast. I remember the exact road I was on. You never forget that kind of power. What a rush

I had one just like it 😍 but mine was a 1975 , single front disk , love that two stroke sound , dam fast too !

Bought one of those new from a dealer. Could not keep the front wheel on the ground. It would wheelie at the most inopportune times. I installed a Vetter fairing and that helped. It would get to 115 in no time. Got rid of it as soon as I got it paid off.

Poppy chambers hard to find those..Very well restored.It can handle better with stock handle makes the bike lighter .

Love the sound of a fast two-stroke under power.

I had one like this in 79. Drove it all summer. Shut it off one day, never fired after that. Left it in my dads garage. I think some guy bought it from him. Two loves that summer. The bike was one of ‘em.😉

That’s awesome it’s till around and looks and runs as good as it does! Cool vintage bike!

Man, those triples were just fun!🔥👊

Your shop makes old bikes look like new. Great job . Love the old bikes.

Two stroke street bikes are just a local myth around here. I saw one 15 years ago I haven't seen one since.

Beautiful went on a nostalgia trip . Had one just like that .

I went to high school from 73 to 78. The Headmaster at my high school had one exactly like this. And his son had the Honda 350 four. Two diametrically different bikes. The Kawasaki sounded like a bunch of stray cats in a bag and the Honda was like a sewing machine. Needless to say this green and black 73 Kawasaki triple is my favorite of all bikes. You guys always make such a professional presentation. Thank you for preserving these old bikes. Some lucky rich person is going to own this now.

I bought one of these brand new in 1970 and rode the hell out of it. It cost me $995. This brings back memories for sure...

one of my favorite rides, had one with clip ons and smoked emgo cafe sheild with pipes.

Last 2 2 strokes I saw on the street were a RZ350 and a RG500 Gamma several years ago..

My brother had one ( H1 )when I was a kid and I ended up with a 76 RD 400 I bought back in 1983 and still have it. I always wanted the H2 but would easily settle for this baby. Great video, thanks for sharing and cheers from Canada!

Very cool bike, great fun to ride, wish they still built em.

The bike is a legend its when something special rolls out of manufacturer

I had a 74 in the same color . Loved the power and that adjustable steering dampener.

Not bad ... Sound's a little rough . Setting these bikes up is an art . Nice bike , beautiful rebuild .... Excellent bike .

Very nice, I had several 2 stroke bikes growing up, dual purpose they called them, ride the woods in the day,ride to town at night. True freedom machines.

When you let the gas go, it sounds like Hendrix or Clapton. Sooo sweet.!!

I have owned and ridden many bikes over the years but my absolute favorite was my 1975 H1F 500!!! Oh My God Wicked Fast!!! I bought her in 1977 from the original owner with only 200 miles, he was afraid of it! I rode that beast for six years when I finally had to rebuild the top end...I may have gone a smidge beyond what the frame and front fork was able to handle!!! After my break-in period was up I opened her up on Rt. 95, pegged the speedo, hit an expansion joint on the Piscataqua River Bridge, those of you from my area will know where that is, and went into a high-speed wobble, something I found out much too late that they were prone to dut to the horribly underbuilt front end. Of course, my overbore of the engine didn't help! Yep, totaled! My current ride is a 1973 CB 750 barn find. it is tough to beat those '70s pieces.

I had a '74 Kawasaki 400cc i believe it was...3 cylinder 2 stroke...it was pretty fast!

I bought one new in 1973 - same color. Traded it in for a Z1 the next year. Good memories - nice to see this one in such good shape.

Visited the museum last month it is the Mecca of motorcycles.

Reported for highly sexualized content .

Be prepared for 2 things ... 1. chassis flex and 2 a big surprise at about 3500 rpm on wide open throttle as it comes on the pipe ... hold on!

My dad had a 350 back in the day from new absolutely quick for it's time I wish that I had it today awesome bike 😊👍

Kap good job slowing down for that woman pushing the baby but you know you just made a motorcycle fan for life😁

Easy to see you guys just love all bikes and This Country ❤Respect

I had a 400 and 500 triple. Had a lot of fun on those bikes

I had one while serving in the Navy in VA and abandoned it in a field before a world cruise in 82 😢

The Gary Nixon jacket adds a nice touch!

I got passed, like I was standing still, by one of those while on a flight to Reno, Nevada.

Ill never sell my kawasaki green 73 h1...dad made me sell the first one in 1982 a 74 kawasaki green h1 and I never forgave him for that...Im 57 years old, and an old woman now-- but still ride my 6 vintage japanese bikes when the carbs arent being a PIA!

Was a beast back in the day,power band was scary

Hell Yes!!!, Awesome machine! Don’t make em like that anymore.....

Super cool sound😁

My brother Jack had the H2 750 and a 500. Nothing like a 2 stroker on the pipe

A screaming 2- stroke polarizes: Some hate that noise , some love it. I love it.

You need to tune that puppy......

Just plain music to my ears and you rarely get a glimpse of one anymore! We have two rd350s in the family and they are killer bikes.

Nice! Bought mine in 1977 used $600 lol always loved that color ❤😉

What a beauty ! I had a Yamaha RD400.

I had that exact same bike, very fun to ride, a wheelie monster

Awesome bike, but back in the day, I smoked these coming and going on my Yamaha RD350

My dad had one when I waz a kid... She’s leaning on to much gas! The have way more power/band than that in Europe. It’s not Jettit Accordingly! I used to ride this 2 gear up drop it 5 gear Thought all gears wheelieing. Best bike ever! Small question? This or a CR500 Supermoto? GBA!

I bought a new 1969 Mach III, had the dealer install the optional (slightly lower) gearing that dropped one tooth on the front sprocket and added 2 on the rear, final drive. 1st and second gear were the wheelie gears if I were riding solo, 3rd gear would also pull the front tire up with a passenger on board. I weighed 160 at the time, I could not keep the front wheel down even if I had my balls hanging over the gas tank. Fun bike for straight line racing, piss poor handling in the corners. I raced all comers, never lost a drag race! Even another 69 500 couldn't come close. That guy went back to Mt. Vernon and probably got the optional gears like I had. It wasn't even a close race. I can only imagine what that bike would have been like if there were longer swing arms like is available on some of these 200+ hp motorcycles. I lost a lot of speed going to a 69 Triumph Bonneville, but boy could that Triumph handle!

Used to own one street full of blue smoke luv it

I had a 1970 H1 in Candy Blue FCH911J (UK) Fabulous machine.

Awesome. Put the stock airbox back on it will run a lot better.

I hung in to a 750 Law once, what a ride

i had that exact bike same color and all xcept the exhaust i gave 500 bucks for mine it was a fun ride for sure

That bike sounds awesome! Thanks for sharing.

My pop had the same bike in the root beer and orange paint scheme. Said it was one of the few bike he had that literally scared the sh*t out of him! Keeping the front tire on the pavement was not an easy job! lol. He ended up trading it for a '75 z1-B 900, which he's still kicking himself for ever letting go of.

Way better sounding than my 73 Yamaha IT175 2stroke

Miss my RD 400 RZ 350 owned mint ones the RD was raced and in a barn for years with a factory new tank still in the Yamaha box!

I love that beast from Philippines

Had a 73 750. Wild ride.

You just can’t beat the Pure sound of a 2 stroke

My friend had a 250 s1 years ago very addictive sound specialy through tunnels 😜😜😜😜👍

I had a 500 Triple in high school and I'll tell you what I had fun with that bike 1970 I would love to do that one more time if you get a chance to get one of these bikes you will never regret it because nothing compares to it nothing you can get a Hayabusa but it is not the same thrill

Ultimate Kawasaki Street machine there and I'm a Kawasaki man all the way Ken

Nothing sounds like a two-stroke triple when you're givin it to her!🤙

My very first bike at 8 years old was a Kawasaki 65 KX and that front wheel would come up in every gear

Had 2 of those, sure miss the music!

On my bucket list. Green or Blue, decked block and head, two into one, 2/3 fairing, cast rims, premium rubber, crash bah..

7:49 min. worth of awesome memories chrned up here.

Two stroke heads couldn’t be simpler. Just lots of fins which look cool and keep it cool. My 82 KE 175 had 10,000 miles when I sold it. Should not have sold it. Ran like new.

J’adore, les deux temps c’est le top, un vrai plaisir.

In 1969 I had a '68 Suzuki T500 Titan and my cousin had a '69 Kawasaki H1 500. The H1 was, of course, faster; but it did not handle or brake too well. Still it was an awesome bike which advanced motorcycling to a new era of performance. Would love to have one in my stable for riding around the neighborhood. But alas, its down the list a ways since its not really the best for a trip of any sort. I'm guessing the modern tires on this bike and the dual disks on the '73 improve it vastly over the early H1s.

2スト最高の時代の名車だな。 高校生の時にこのカラーリングの250に毎日のように乗ってた。GTさんぱちと農道をアクセル全開で走ったら白煙で後ろが見えなくなっていたのを思い出す。もう40年以上前の話。歳くったな〜。 でも今もkawasaki 好き。　٩( ᐛ )و

The widowmaker. A guy around here was left paralyzed by one of these beasts. Average handling, little to no brakes, but when you hit that power band you're thrown into the next dimension, lol.

Great video fantastic bike sounds amazing stay safe 🇬🇧👍🏻

I think the early ones had a plate to hold spare plugs because they sooted up so often.great bike

I could feel it when it hit the power band!!

I had the 1976 KH 400 Kawasaki great little bike

Badass the Mach 111 sounds like my old Polaris Indy 600.

That's a bad ass bike 👊

Watch all your guys vids, finally have my favorite bike on video. Actually my favorite is the blue or orange 72 h2. My paps has a 75 h1 500

those 500 h1's flat hurt ya i see that one has expansion chambers nice !!!

There's something about that 2 stroke sound... Said by someone who loves v-twins.

a beast you can tell by the noise it makes . if ya wanna know why kwakas are green .to the japanese green is a lucky colour

This is definitely a survivor!👌😎🇺🇸

Sounds so nice 🥰and really how much fun is that bike eh ! So fun to ride ! And looks sick 🤘🏼spot on boys !

That sound 🔝

mine got hot and locked up..need to repair

I was exposed to these in 1975 at the age of 7. My childhood buddy's two older brothers each had one and later the father of one of my babysitting mates' dad had a 750 mach lV that he would roll up on every few weeks. Lol then later yet, the older brother of a girl we were all pining after had a 1975 500. I was riding a moped at the time (15 yrs old) but he took me on a few rides then one day let me ride (ing since 9 yrs old) it. It was the first street bike I'd ever ridden. ADDICTION.

Great sounding idle

Badass bike.
