2:34 Twin spark plugs, no radiators, and an expansion chamber bigger than the fuel tank... damn that thing is raw!

See those 500s rocket up that hill, especially that 1st 1. Made the 450 4 strokes look slow and gutless.

That CR500 is no joke! Years ago, a buddy I used to work with took a CR500 motor and swapped it into his 250R racing quad. He had to do a little welding for it to mount properly, but he got it to work mint. That quad was balls to the walls scary fast! I was following him in my car once while he rode it home from the trails, and after a red light turned green, i watched as he left 50 yard strips down the street ripping power ban through every gear. That monstrosity of a 4 wheeler was a loud, eye watering fast, force to be reckoned with, for sure. He smoked Banshees and ate quadzillas for breakfast. Definitely the craziest motorized vehicle I've ever had the pleasure to hold onto as it took me for a ride lol.

I grew up on screaming 2 strokes. I had a CR 250r that I still remember fondly. When everything went 4 stroke I honestly couldn't bear the sound of them. lol....So it's great to see the old 80s CR's cleaning up like this.

The 1st CR500 was crazy !!!

Just hearing those bikes puts a smile on my face

The two strokes once again prove Who is the king of the hill.

I raced an 86 CR500 in the open class years ago, a beast to hang onto! But hands down of all the dirt bikes I rode and raced over the years the big 500 CR was my favorite. Never have I been so thrilled to be terrified.

the pipes on the 500s were nuts

Don't leave us hangin Sr!

That first big 2 is a testament to perfectly dialed big 2 stroke magic! F-ing amazing!!! 🤩❤️❤️🇺🇸🇺🇸👍💥💥🔥😎

That Black CR500 was crazy!!! Max power from start to finish! Kid killed it🤘🏼🤟🏼⚡️

I did a lot of pipe calculations as a young man and I always thought you could never fit an optimum sized pipe on a 500cc bike. Figured you'd only ever see one on a 500c speedway car.. That black and red CR 500 proved me wrong.

В 90 тые годы жил я в г. Подольск Московской области, так у нас была девчонка звали ее Изаора, отец у нее был тренер по мотокроссу, она такие чудеса на кроссовом Чизете творила что тем кто в этом видео и не снилось. С 9 лет занималась в мотокроссе у отца.

Holy crap, those 500s are vicious. Sound of music

Man notice that bike turn in to a completely different beast was one of the most badass things Iv seen/heard.

God I love the sound of a 2 stroke. Sounds like freedom. 🇺🇸🤘

Those CR’s whooped the 4 strokes !!!

Just something so nice about a 2 stroke sound

Absolutely no comparison with two stroke versus four stroke it’s not even fair lol

It's a proven fact that the cr 500 motor was the best race motor ever made.

Ken:"Holly Shit"! You're absolutely right Sir 💥

That 1st Cr500 was insane! Absolutely Love mixing gas and kicking ass.

I love these video's man! Watching a bunch of 500 2-strokes totally unleashed is awesome. Thanks much for posting them Ken. The 4-strokes that rock are 750-1000's and the Harley's.

that first CR blew my hair back on the computer!!

I rode a cranked up YZ465 in my riding days and I could climb things my 4 stroke buddies couldn't touch. Nothing better than 2 stroke power!

Man those 500's just fly up that hill, now that's some serious 2 stoke power.

Gotta love a 500 2 stroke. The Rhode Island flat lander coming in and showing them how it’s done.

2 strokes ruled this meet. 1 thing that chaps my ass though is people laying on the rev limiter. Obviously they think it sounds cool, but I think it sounds like they know nothing about engines.

Got to love the 2strokes love the sound and speed .quickness .the 4strokes just sound like there struggling and puking all the way up the hill .but great vid bud godbless and stay safe

Reminded me when we were little kids, tearin up my brother’s ‘Zuki 125 climbing hills, (sorry bro’ that wasn’t my bike to bust up…iou), then we we started ridin the CR250, we were so little-it was so huge to us, mad power, alway catchin air on little 6’ dips, so fun, and suddenly the sun went down. We didn’t know a day had passed so quickly. You are only allowed a given # to spend. Great video, bad-A bikes, thank you!

thanks for posting ken ive been riding open class machinery since i was 18 i can say i am one of the few people still walking on planet earth who has owned a cr 500 the kicker ripped a big hole in my boot tx 10 honda line

That roost at 3:30 is insane! Long live the big bore 2 strokes

I’ve only been on dirt bikes a few times, I stuck to my cruiser but with my limited dirt experience the 2 stroke I was on felt crazier than the 1 linger did.

Nothing better than good old hill climbing!! Thank you!

That 2 stroke sound just does it for me every time no wonder these things are rocketing in value.

It was a beast in the 80s and it's still a beast today.

The 2-stroke was and will always remain invincible

The good old days of 2 stroke.. I had a KX 500 in the 80's what an animal, wish i still had it.

Thank you for all the videos all the bike you show are the ones that I've written my whole life very cool thanks again

Number one comes up and it ends 😂. Funny guy you are. Where’s part two 🇺🇸

man I was so ready for him up next and then the video ended. what!!!

We had a sandpit near our farm in upstate NY back in the 80's. Everyone tried to climb it,.....the only one ever to do it was my ported 250-r with wooly boogers. Long live 2 strokes!!

I miss that 2- stroke sound un our streets....godi love that simple technic

2:17 when you get that certain ping from the expansion chamber scavenging all the fuel, you know she gonna rip.

If you don't get chills and smell the Klotz at 3:25 you didn't grow up pre 2000... "2 smokes 4 life!"

Didn’t realize this was a Kaplan america video till the first 2 stroke came on and i heard his voice. Great video!! Love me some 2stroke hill climbing!! Rock on!!

Thanks for this! Awesome recording!

The CR500 is a crazy bike, bone stock it had about 61Hp. Gotta love the insanely of 2 strokes.

Holy hill climb 2 strokes foeva!

Thanks for sharing! That first #357 CR was sick !

oh the sound of those two strokes!!! I can smell it from here. Love it!!

To me, it sounds like the four-stroke are struggling!!!😮😮😮

2 Strokes Rule!!!They even sound Faster.

Really liking this channel. These bikes are awesome

This vid so smacks the freakin' crap out of that hill. The bikes are quite frankly phenomenal and so are the riders who have nads bigger than King Kong and don't worry the gal is all guts & skill too make no error they are as equally fantastic to watch as the boys. I rode both 4 stroke singles [500cc & 600cc] & my 1981 Suzuki RM 465X during the '80s over here in New Zealand. I was an apprentice automotive engineer on GM trucks & buses [Bedford & Isuzu] I swapped my 1979 Honda XR500 for the 1981 Suzuki RM 465X [mate's bike]. The RM465X was the most powerful motorcycle I have ever ridden - it was an ex-race bike and I think it may have been re-bored. The powerband was so vicious I fitted a Boyesen Reed to the inlet manifold to try and smoothen the powerband out and it worked perfectly. I wanted to do high speed max running over long gravel roads and so tall geared the bike [smaller less teeth on the rear sprocket and a bigger more teeth front sprocket sorry I don't remember the exact number of teeth for both sprockets. I ran the engine on Bel Ray 2 stoke oil that was very expensive at the time. I considered also using ethanol/methanol blend for fuel, however as I couldn't afford to pay for repairs if the engine blew/seized or the top of the piston melted due to excess heat from the incorrect fuel/oil ratio, so I just used pump petrol at the time. Still the bike performed excellently over long gravel road running at max speed. Unfortunately the bike never had a speedo so I couldn't measure speed. Plus I was light in weight [70kg] and 170cm/5ft 7in in height. I actually convinced a mate to pillion with me and the extra weight proved beneficial for traction. There were the odd corner/bends in the road and so I could power-slide the bike exiting and that was more fun than ever. I have ridden many powerful and fast motorcycles over 10 years during the '80s here in NZ. The story to my final bike; a 1985 Kawasaki GPZ 750 Ninja is worth reading. Here is a pic of my 1981 Suzuki RM 465X: www.flickr.com/photos/35707376@N00/50855348636/in/album-72157713681398176/

That may have been a cr500 chassis but that was a banshee 350 motor

The raw - usable power debate has been settled

Badass video boss man!!! Haven’t been to a hill climb since I was a kid, sure brings back memories.!!

How do ya win? Too many make it to the top, do ya go until the last man is standing? Or is it all by fastest time?

The key to hill climbing is keeping the revs up and hit the hill with speed and don’t let it bog down.

2 strokes rocks 💪🤟

You keep the flag of two strokes high mr Caplan, With your great videos!

I love the Sound and smell of 2 Strokes! 😍 ♥

Ken you gotta find out what's been done to the first CR'S engine! That thing sounded PRETTY DAMN POTENT⚡⚡ 😊

15 years later and 2 STROKES still RULE 👌👌😉😉👍👍

Ronnie Mac would be proud to see at least 6 or 9 of those 2 strokes kicking ass!

wait you cut the video right as that black #1 4 stroke straight pipe pilled up, i was curious on how it was going to do and how it sounded

That 500 is the definition of 'rocket ship' holy smokes! I wonder if even a stock 500 could conqeur that hill

Biggest 2 stroke I ever rode was a 360 KTM. Can’t imagine what a 500 feels like. I was just a kid on the 360 so I could probably handle it better now.

Wow huge hit video major views man rock on! Everyone loves these CR500s!

Man nothing like the sound of an.old school 2 stroke! Always loved hondas when i used to ride! My brother had a cr 80 then a 125. I rode a yz250 and an xr350r, fun times! Those 500s mske the hill look easy!

Wow! Those 450s sound like they are struggling lol. The first 500 was nasty! And elec Start?

If you were behind that first 500 it would be worse than a shotgun blast

Those big bore 2 strokes just give me cold chills.

The rooster tails coming off those 2 strokes is so cool. I love Motorsports in the dirt, so much fun

You're gonna need a bigger hill if the 2 strokes are allowed to play.

The 500 2-strokes have the perfect power for that or lots of mid-range torque at a lower RPM compared to the 4-strokes.

My cousin bought the first 1985 CR 500. It had the most horsepower of all the years. It is one hell of a hill climber. Always smoked the 4 strokes on the way up!!

Any Kawi triple powered bikes at this hillclimb? My 2nd favorite sound next to a big bore 500!

They may have to make the hill steeper and longer for those CR500’s. Badass!!

3:35 "Holy shit" 😂😂😂 I said the exact same thing the same time

I am an old retired Diesel Mechanic and I was a Detroit Diesel Specialist, nothing creates raw Horsepower at the throttle like a 2 stroke. Bike or other wise less moving parts and power on every stroke.Beast they are.

Reminds my of my young riding days, thanks.

@3:35 I said the same thing..that bike was wicked!

Just ask Uncle Ron what he thinks of the four strokes.....

What gear are you using?

What was that thing at the end before the video cut out ??

Two strokes gone, solar panels here, electric cars here, diesel particulate filters and DEF here, big V8 gas guzzling muscle cars soon to be gone…. What happened to America???

Hard to beat the torque of those 2 strokes.

what preparation was there on the first 500 cr?

Man, you can shave hair with the sharpness of the exhaust note alone! Those 80’s CR’s and KX500 makes it look easy! Golden era stuff.

god dayum that 500 showing the 4s kids how its done xD

That’s awesome non of them cr500’s had radiators

What/where "HILL" is this? It looks very similar to Mankato, MN. ..?

love the strokers, thanks for the vid.

ive owned 2 stroke 80s that were faster than them four strokes

Angry mosquito for the win. Hard to beat a two stroke with a good pipe.

@KAPLAN AMERICA thank you . Wondering why such low Tom's (it seems)?

What was the last bike in the video ? I would love to know more about it !
