No it isnt, it just got a very generous review. In reality, nothing compares from power delivery, to brakes, suspension, handling or ergonomics. The only thing thats better is the nostalgia attached.
I was 13 when this bike came out, and I remember the lust I had for it. I had a old clunky KE100 at the time (trail bike) which I totally loved, until I discovered 80 cc Motocross bikes. Memories!
My starter race bike was a 1985 KX80! Amazing machine. My 1st bike was an XR75. Can't beat Kawasaki & Yamaha in Mini MX or full size for that matter. Ride for life! - Ohio 🇺🇸
I still remember riding a 1984 KX 80 compared to my 1982 KX 80. Those water cooled models were, and still are EPIC! Awesome restore!!! I want one. I'm 46 at 230 lbs and I'm sure that little 80 would make me smile for weeks. Great video guys.
I had an '83 KX80 and an '84 KX80. Helped a buddy break in an '85 KX80, way back in the day. These were the kings of the Mini class back then. Was a sea of green at the start gate. Back when these were new, we'd go get a 99cc "Power Up" kit which would allow for 3rd gear starts like an Open bike and messing with many 125 riders.
Not really much script mate I was there on the day and was actually filmed was supposed to be on but couldent fit me in cause time limit for tv. The first 40 seconds of it is scripted the rest is stuttering trying not to swear. Lol

Kawasaki used to invest in their bikes and the youth side of the sport to build for the future, now they do not care, KTM are the MX market leaders end off, Kawasaki are broke and do need to fix up both their bikes and ethics! They are content with the road side of things but can't see that KTM are well on the way to dominating there anytime soon just as they let that small fish come along and eat them up with the MX!!!!!
I campaigned in the Florida motorcross club on a 1986 DMC KX 80 G1. It had 27 hp! Total dominance on the straightaway! Man I miss those days. Anything more than 2 strokes is masturbation!!
Back in 1987 (when I was 16-years-old) I also rebuild a scrapped '83 KX from the frame up! The frame was cracked, the engine was seized, and it was completely worn out. It took me almost 6 months to complete, and I likely also had 250 man hours into it. When I was finished, it looked and rode like a new bike--just as nice as the bike in this video! I sold it to a friend for a loss, but the experience was worth it. This video brings back fond memories! Thanks guys!!
Absolutely sweet KX80, a truly rare sight to see one of these old 80cc mx bikes even running, let along being in perfect condition, thanks for uploading!
Thanks for the great video guys, looked like the kid had fun testing both and did a great job describing the differences! I love the old bike vs new bike comparison videos, keep it up! Cheers from Southern California!
Drum brakes may be the same when they're cold, but after a couple laps they fade away to nothing. I have a '90 Yamaha YZ490 with a drum brake on the rear.. it's downright terrifying.
breaks never won a race.... the throttle dose.. ive race drum for 25 years.. never an issue till they get wet.... then better know how to engine break well
Well guess what... drum brakes are all they had for years and years! I don't ever remember Bob the hurricane Hannah crying the blues about his drum brakes. 🤣
What I meant is the reply "so 2 strokes are faster" It won't go faster just because there's no limiter. I'm not saying which one's faster, just don't get Will Lackey 133B's reply.
When the bike hits the high RPM and you feel the power come on that is a two-stroke basically supercharging itself there is no physical Power Band part there is an exhaust valve but that's more for a low RPM stuff
I almost bought a 1984 KX80 when i was a kid, but i ended up with a new XR100. It may not have been a 2 stroke like i wanted but i was so proud of it, and rode it all time.
Hi all.. just to clarify for you all, you Cam said you have to ride it on the rev limiter so I'll explain what he means. These f1s had little bottom end with a huge mid to top end and no power valve, they had to be ridden wide open and on the clutch. When he says rev limiter, he is referring to the break down of the ignition and very much sounds like a lean pop that these bikes had, especially on gear change. It was a very distinctive sound that just these early kxs had. Saying rev limiter is a now a day term because back in the day they didn't have one, it's just the ignition over heating, it was fixed in about 86 but in this case the engine was ported for even more top end making that ignition pop way more noticeable.
I had a 1983 KX80 Dad and I bought it new right off the dealer floor in 1983 I was 13 years old first motocross bike. Go to the track every weekend and I would spend an hour washing it cleaning it up. Never placed any motos usually last 5 to finish most kids who did parents were rich had big trailers lot of mods to their bikes I still had fun. Later I gave up the track did lot of desert riding with friends then sold it moved up to KX125 then to a 87 KX500 by then I was 16 driving an old pickup to Glamis Dunes in Southern California loaded down with bikes. Lot of good memories my father passed on now we sure had fun. I did bust myself up couple of broken wrists and some knee damage.
I got a brand new kx80f1 for $990.00 at the age of 13 .from john&bill Crawford in glenroy after being told they are a great bike from craig and shane gardener.i rode it every weekend at broadmeadows motorcycle park after 4 years I cracked the frame next to the airbox .Overall it was amazing motocross bike along side the YZ80K-CR80RD-And RM80XD.
Back in my day! When the only 4stroke MXers were the XR75 or maybe XR80. Kids have it made now, soft clutches, easier handling, lighter weight etc. etc.
You guys need to do this type of video with other bikes like hondas. I know most of the other companies have discontinued their small two strokes or two stroke lines completely but it would still be cool to see just how far the companies have come.
In 1994 I got a '92 YZ80 - the year model before Yamaha re-invented the 80cc class. Was awesome to have a bike, but boy I wanted the 93 model so so bad.
killerkork Hi mate, every motor ever built has a power band, or power curve. But you are right, it's just the top of the power band curve he was discribing. Throttle wide open!
Yeah I was going to explain what a "power band" was but you did it for me. People think it's a piece of equipment. Fucking idiots. Like you said, EVERY motor has a power band.
I'd much rather the older one. Its the noise itself, i don't know. Also mainly because i ride my grandpas old Xl250s (78) so i think i've become fond of the older bikes. Tho the new bike would be a blast too. Just having an old bike is very appealing to me.
I had the same bike but an 84 kx 80 it didn't change much for years. It was a beast of a bike and in many cases was faster than my friends new bikes at the time. I couldn't even touch the ground when I first road it my dad road it then told me I could grow my toenails to reach the ground lol He flipped it the first ride home and said this would outrun his 750 street bike 0-40 at least haha After that he always found used KX's and built them while I never had a new bike I often had the faster bikes. My 84 kx 125 was amazing as well! Me and this young man is lucky to have awesome dads! Only wished I kept all the bikes he had bought me.
Got one just like you have the old one like I grew up with just shows you so have the bike's have changed luv the new 2019 yz 85cc they just came out with the power valve they have been it's the fastest yz so far luv too add to my collection of dirt bikes I have bought over the years great video will be looking for more videos in the future thanks again for all the great work up Mike holden said that out of North Carolina
finally a good comparison on how bikes evole but notice no suspension test that 80's bike would bottom out so hard lol but back then tracks didnt have the jumps we do today
That's a really smart rider. The kids feeling it and was able to translate it. My 2003 KTM250SX would easily keep up with a 2020 version of the same bike, it might then be a bit faster. But it's Pro level power output, you BETTER be pointed in the right direction when you grab a handful of throttle. Remember, all Jeremy McGrath added was a pipe to his factory bike to smooth out the power. And every year since my none that's what KTM had been doing, making the bike easier to ride for the average rider. When I tested the 2001 factory bike if John Dowd I was blown away that I could pull a 3rd fear start on it with no bog or hesitation. 2 years later I bought the 2003, keeping this bike forever. The new chassis and suspension obviously allows a rider to go fast with less effort. The Pro level nature of the 03 250SX demands that you are in good shape. But again, I'm impressed with this little kid. There are local Pro rides out there that can't tell you what the bike is doing. "Good on ya, Mate."
No difference if front brakes until you get them wet. My first motocross bike was an 83 KX80, I was 13 in 1983. Next year for 1984, KX80 had a disk up front. Much better with a disk on wet tracks. Also the 83 was notorious for waterpump seal leaking coolant into the oil due to the rubber grooving out the impeller shaft which was on the end of the crankshaft. Only fix was to replace the crank.
I had an 87 KX 80, it come out stock with an 82cc barrel. SCARY, SCARY fast. It broke down every second time I rode it though, but yeah, sick bike, great memories. Just quietly, that’s a great resto sir, here’s too ya 🍺👍.
I asked this actual question to my brother only recently! I thought there would have been masses of difference in speed etc between the years, I dont feel so bad now as thought evolution meant I was a lot slower than the kids of today and now I know it is only marginal :-)
I had one of the F1 bikes back in the day and I will tell you this it was a screamer my buddies hated me because my bike was way more gruntty on the bottom and I would spank them off the line every time. The rest of the bikes revved higher but by the time they got wound up I was already way out on them. Team green since day one.
GREAT VIDEO I have a buddy that had that same bike his dad paid $700 for it brand new. We rode the shit out of it. I had a 83 yz 80. The kawi was one impressive little 80 and so was the yz.
They have found and tested an 81 Susuki RM to do a comparison. The 1980 to 1981 RM 80 was the fastest bike in the history of Motocross production in the 80cc class. Not many people or mechanics or riders ever questioned that fact either. They actually went back to that years engine design many times. The engine itself that year was found to have been a flawed test engine design that Suzuki under poor management chose over their intended design accidentally. And then thrown together in a hurry. That engine was the smallest, lightest, had the smallest crankshaft and the smallest stroke of what was never intended to go into production or to have been considered feasible for an 80cc engine. Its was intended and meant for shipment to bottom market countries as a cheap replicate-able one off of its high class big brother 80cc as a toy. Somehow the torque and power-band ratio with the tiny stroke unintentionally created a whirlwind effect causing the crankshaft to spin on an inertia almost twice as fast as any engine of that size and 79cc bore. Unbelievable quick throttle to ground response launches on that bike. The bike did have its problems though. It was cheap in the frame components and the foot pegs would break off. Our team broke six frames in the first season. We had to heavily modify them with tig welded bottom engine mounts to dampen the vibrations causing the lower frame tubes to crack. But that bike and anyone who raced it could enter any 125cc class or an open-class against 250's or larger and win it. It was just that fast and quick. I raced the Kawasaki 82 model water cooled also. Bought it brand new in Lubbock Texas. It turned eyes but on the track it had its problems also. Mainly the engine mounted water pump was mounted to close to the engines head and the plastic impeller shaft would melt after a race and had to be replaced. They finally came out with an aluminum replacement but by that time it was too late. The most troublesome though non mechanical was the radiator mounting brackets. We wound up having to wrap them with copper wire twisted around the mounts with duct tape to stop the mounts from busting the radiator and splitting it open. The copper would allow the rubbing to damage it instead of the radiator. Kawasaki also in 1982 had the widest conceivable handle bars of its time. Bike was easy to manage but could get you banged up in tight spots though. Lol Its good to see other youngsters having the thrill of a time likewise. Nice Video. I'm too old now to get on one but I do still drive a Honda TMX 125cc here in south east Asia. Our trike is a 1975 Kawasaki 2 stroke incidentally with a power expansion muffler added. It can haul 20 sacks of rice weighing 106 kilos and move really good. Lol Besides toting the family of eight around here on the Islands.
That 80 is putting up a hell of a fight for being almost 35 years old!
This only proves that 2 strokes haven't really changed that much over the years...
vertti syrjälä if it ain't broke don't fix it!
true my old 1990 kx100 is still a fast little bike
1982-84, my fav KX era .. what a great time actually for bikes in general, now its all mixed n crap.

Glad to say I helped building the 83 one
Those old 80's were fast bikes. To only be 2 seconds slower with 29 years of R&D is pretty damn good if ya ask me. Awesome restore man.

2 strokes don't have a rev limiter
Quincy O'Connor so 2 strokes are faster
I don't see the logic there.
hes right. they rev until they physically can't go any higher
What I meant is the reply "so 2 strokes are faster" It won't go faster just because there's no limiter. I'm not saying which one's faster, just don't get Will Lackey 133B's reply.
enthusia86 gotcha fam
I woke up to one of those next to the Christmas tree in 1983. The glory days of my youth. Thanks for the flashback. ;-)
When he said "On the rev limiter" I think he meant to say "On the pipe"
Chase Hewett I think he meant powerband mate
Mitch ! But there is no "powerband" physical part.
Chase Hewett kinda it would still have a similar thing to the powerband in the high rpm range
When the bike hits the high RPM and you feel the power come on that is a two-stroke basically supercharging itself there is no physical Power Band part there is an exhaust valve but that's more for a low RPM stuff
But then I could be totally wrong seeing I don't really ride 2 strokes and when I do it's a 125

just remember it's a thirty year's old but to be honest it is pretty good
that 83 is a beauty
Had one for my birthday at 7 thats where it all started.. cheers dad.

I had a 1982 KX80 back in the day. Even though it was only a year older than your 1983 KX80, the 1982 version was air cooled. It was great fun !
I had the 81 & 87 KX 80.
Big difference.
Drum brakes would wear out in 1 weekend.
Disc was great on the front.
Rear drum is more controllable.
My second bike was a 1985 KX 80!!! This is awesome! I raced my first season of motocross on that bike back in '93!!! This is cool!!!
This is a great video concept. I'd love to see more like this.
lolm found ur comet lol

Oldie but goodie. My first bike was an 86 kx80 back in the day.
84 KX80 was my first bike, what a way to start, wish I didn't outgrow it so quickly, damn growth spurts.
I had a 1983 KX 80 . Best days of my life

That would be the KX 80 F2 first KX80 to come out with front disc brake
Put that gorgeous '83 KX80 in secure storage! It's a work of art & built w/care & knowledge for sure . - Ohio 🇺🇸
Brings back memories. I had a 1985 KX 80 in the early 90's.
I'm 51years old and yourned for that KX80 back in the day so much that I couldn't see straight, never got one.
Was my first bike back in the day when i was a kid good ol kx 80 !!
Cool comparison!!!! 2 strokes for life!!!!!!
You guys need to do this type of video with other bikes like hondas. I know most of the other companies have discontinued their small two strokes or two stroke lines completely but it would still be cool to see just how far the companies have come.
I had a 1983 kx 80 and to this day that’s my favorite 2-Stroke I ever had !!!!
Great video guys! I also had a '83 KX 80 back in the day, great little racer had lot of fun on it. (long time ago)

Older bikes tool so much more effort and a slightly different skill set to master
i had an 82 kx 80. i smiled during the whole video.
I had a 1984 about 2 years ago and the thing kept up with all the new 85s at the track mine had a bit of head work done tho
the 83 kx was a monster when it arrived. my first mx race i was on a AIR COOLED cr EVERYONE ELSE WAS ON A KX
I raced on of those back in 1983! It definitely was an up grade from the 82 model I also raced.
I have a 1986 Honda tr200 and that thing is a monster. it unstoppable you can go through or over anything in your path.
I had a 82 KX80 in my younger day. It are my my mates watercooled RM80
I'd much rather the older one. Its the noise itself, i don't know. Also mainly because i ride my grandpas old Xl250s (78) so i think i've become fond of the older bikes. Tho the new bike would be a blast too. Just having an old bike is very appealing to me.
I had the same bike but an 84 kx 80 it didn't change much for years. It was a beast of a bike and in many cases was faster than my friends new bikes at the time. I couldn't even touch the ground when I first road it my dad road it then told me I could grow my toenails to reach the ground lol He flipped it the first ride home and said this would outrun his 750 street bike 0-40 at least haha
After that he always found used KX's and built them while I never had a new bike I often had the faster bikes. My 84 kx 125 was amazing as well! Me and this young man is lucky to have awesome dads! Only wished I kept all the bikes he had bought me.

It’s amazing how little these have changed compared to cars.
thanks for this match up interesting to see bikes from when I was 12 put up against today's best very surprised in the end result
Had the kx 80 f1 1983 was a great bike very quick for its age handled well great down low power top end pretty good great looking bike
That is a GORGEOUS old bike!!
finally a good comparison on how bikes evole but notice no suspension test that 80's bike would bottom out so hard lol but back then tracks didnt have the jumps we do today

The rest of the bikes revved higher but by the time they got wound up I was already way out on them. Team green since day one.
Awesome, lucky feller, grate vid awesome bikes,
GREAT VIDEO I have a buddy that had that same bike his dad paid $700 for it brand new. We rode the shit out of it. I had a 83 yz 80. The kawi was one impressive little 80 and so was the yz.
I love how the old bikes look
I had the 84F2 KX 80 ..... I loved that bike..
Just like I loved this vid
before this even began thumbs up excellent
My bike is 30 years old. I have a 1984 yz 80. My brothers got a really old Mx 80. If u don’t know these are Yamaha. My dad had this bike.
I'll take the 83 ALL DAY LONG!!
That 83 is beautiful!
Most surprising think was the brakes. I guess the real brake test is how the new disc work over time once they get pretty hot and can stay effective.
wow brings me back to my childhood!
My twin and I both owned '84 kx 80. The older neighbors were riding xr 250s. We kicked their butts riding. We just had the better bikes.
Daym I'd take that 83 without a thought. It looks so good :o
The old beauty running a bit richer I'd say
get out of here! This is the coolest video ever! s this youngster was able to basically try a brand new 83' kx80?? amazing
good work for the kid but its always down to whom is riding it
I was on the 50cc and the 60cc class in 1983. I saw some fast guys rip it up on these 80s
Keep on watching, plenty more of these type of test to come.
Good on ya little dude!
Nice job on the rebuild.
Is that a 9942 yz 500???
Yep 😂😂
NoOoOoOoOo
They have found and tested an 81 Susuki RM to do a comparison. The 1980 to 1981 RM 80 was the fastest bike in the history of Motocross production in the 80cc class. Not many people or mechanics or riders ever questioned that fact either.
They actually went back to that years engine design many times. The engine itself that year was found to have been a flawed test engine design that Suzuki under poor management chose over their intended design accidentally. And then thrown together in a hurry. That engine was the smallest, lightest, had the smallest crankshaft and the smallest stroke of what was never intended to go into production or to have been considered feasible for an 80cc engine.
Its was intended and meant for shipment to bottom market countries as a cheap replicate-able one off of its high class big brother 80cc as a toy. Somehow the torque and power-band ratio with the tiny stroke unintentionally created a whirlwind effect causing the crankshaft to spin on an inertia almost twice as fast as any engine of that size and 79cc bore. Unbelievable quick throttle to ground response launches on that bike.
The bike did have its problems though. It was cheap in the frame components and the foot pegs would break off. Our team broke six frames in the first season. We had to heavily modify them with tig welded bottom engine mounts to dampen the vibrations causing the lower frame tubes to crack. But that bike and anyone who raced it could enter any 125cc class or an open-class against 250's or larger and win it. It was just that fast and quick.
I raced the Kawasaki 82 model water cooled also. Bought it brand new in Lubbock Texas. It turned eyes but on the track it had its problems also.
Mainly the engine mounted water pump was mounted to close to the engines head and the plastic impeller shaft would melt after a race and had to be replaced. They finally came out with an aluminum replacement but by that time it was too late.
The most troublesome though non mechanical was the radiator mounting brackets. We wound up having to wrap them with copper wire twisted around the mounts with duct tape to stop the mounts from busting the radiator and splitting it open.
The copper would allow the rubbing to damage it instead of the radiator. Kawasaki also in 1982 had the widest conceivable handle bars of its time. Bike was easy to manage but could get you banged up in tight spots though. Lol
Its good to see other youngsters having the thrill of a time likewise. Nice Video. I'm too old now to get on one but I do still drive a Honda TMX 125cc here in south east Asia. Our trike is a 1975 Kawasaki 2 stroke incidentally with a power expansion muffler added. It can haul 20 sacks of rice weighing 106 kilos and move really good. Lol Besides toting the family of eight around here on the Islands.
Well I'll be happy to see how this bike goes up against the 2016 model I had one
