These were truly 'terror in a teacup'! The amount of technology that went into these tiny twin cylinder twin-cam 4 strokes was astronomical for the time they were produced. The fact that they actually stayed together for a complete race was even more impressive! Making around 16hp @ 21,000 rpm these little bikes would do close to 110 mph. in the straights.😮
The fact that this has a 50cc twin Cylinder, having 16HP, near a Honda CBR150 or a CB150R, and having a top speed of around 180-190, the same as 300cc bikes. Is just amazing
In 1967, motorcycle GP came to Canada, it was Canada's Centennial year. The race was held at Mosport and I was able to wander into the Honda pits during practice. There was the 50cc twin being warmed up by a mechanic. I walked over and stood behind the little Honda, I could clearly see the tachometer and watched the mechanic methodically blip the throttle to 19,000 rpm. Hailwood and Agostini were also competing. I got to witness a lot of motorcycle legends that day.
The first TT race I ever saw was the 1964 50cc TT.The Hondas and Suzukis were amazing.Most of the other bikes seemed to struggle to reach 60MPH!I was back at the TT in 1966 and again watched the 50cc race.It was a massed start for the first time ever at the TT.But it was a bad idea ...they all buzzed off at the start and we had to wait about half an hour to see them again!
This bike is a marvel of machining. Shoichiro Irimajiri designed it, the president of Sega Genesis video game systems. Achieving 21,500rpm, 9 speed transmissions and over 110mph on a 50cc was a feat for 1966. Irimajiri also made the RC147 5 cylinder 125cc, RC166 250cc six cylinder, 1.5Litre V12 RA271 Formula car, Oval pistpn NR500, and the CBX1000 six cylinder bike. All his machines were four strokes, all hondas bikes in the 60s were four stroke.
That little engine used to do 20,000 rpm when racing, and ended up with a 14 speed gearbox to keep it on song. In those days Honda refused to "go two stroke), and developed the little twin. It had four-valve heads too! They used the same cylinder configuration on their five cylinder 125cc bike. Astounding technology for those times, and I remember them well at race circuits all over the placer, not least the Isle of Man where the little fifty lapped at incredible speed (around 80mph if my memory serves).... Halycon days in the development of the wonderful engines that we now take for granted on our road bikes..... :-)
Walter Tacey I guess it's not quite the same. Those pioneering days are gone, but what was learned then we now get to enjoy every day on the roads. I have a 25 year old Honda CBR600, and such a machine was undreamed of back in the 60s and 70s. The latest versions of it are really 'hard edged' and not for old girls like me these days, but the milder sports-tourers we ride now would have acquitted themselves well at the "Island" back then, and the supersports machines of today would leave those old bikes for dead.. I still get goosebumps, though, when I see a nice Vincent, Norton, Triumph or BSA from that era. The designs were, by 21st century standards, crude, but those bikes had a "je ne sais quoi" that is often lacking in modern iron. Still, it's nice to have a bike that starts at the press of a button, doesn't stop when it rains, holds the road like a limpet, stops on a dime, uses little gas and goes like a rat up a drainpipe! I was off bikes for some 20-odd years from the late 70's, and when I got back on one (a 400 Katana) the advances in tyres, brakes and handling were quite startling, not to mention the sheer grunt of that little 400cc motor. I love technology! xo
@@hh-pk6pl forget the cylinder. Its piston was so tiny just 25cc, smaller than single 50cc. Its equal with single 50cc volume and power. And the end, only suzuki with 2 piston in rk67 with 14 speed that could beat this bike. No one 50cc 2t shit get podium in its last race with single cylinder.
@@febriyogapratama7462 Honda would have beaten Suzuki with their 3 cylinder 50cc bike they were designing but the rules changed and only 2 cylinders were allowed in the 50cc class.
It's a lot more FUN to ride a small displacement motorcycle to it's limits, than a larger one! I have owned many many bikes, and one of the most fun, 'purist' ones i've had is my 1982 50cc, 2-stroke, Honda MB5. It is a 5-speed, 7HP screamer that can hit 55, even with my 220 pound frame!
Some of the craziest fun I've had is with shitty cars. There is something very fun in pushing a SEAT Inca with its 64hp engine to its limits on a mountain road. It's also great fun to scare people with that since they never expect a courier van so stupidly fast around hairpins and all.
I ride a fireblade at the moment which is a great bike; but my most fun biking was my MC21, i paid a small fortune ( to me at the time in the early 90's) for it and it was worth every penny and every penny of every motor rebuild. Get more enjoyment like you say out of small capacity machines.
The RC116 for 1966 was the result of developmental work on the RC115 a year earlier. It was an inline Twin with a 33mm Bore and 29mm stroke. 32mm's is equal to 1"-1/4" inch, so add another .040 thousandth and you have your cylinder bore. It had 4 valve per cylinder and was rated at 16bhp @ 20,500rpm although knowledable insiders say the HP was closer to 20bhp ( Honda never gives true HP numbers) Much like other Honda small CC RRers it relied on high RPM and with the narrow powerband even with redline being over 20,000 rpms, it incorporated a 9 speed gearbox. When you consider Honda's little Street Sport 50cc motorcycle designated C110 and producing 5bhp. This would be a rocket in comparison. as you can see by the Video Demo; if you hadn't been told it was only a 50cc motorcycle, you more than likely wouldn't have believed it. The RC116 won 3 out of 6 FIM Races in 66 and grabbed the Mfgers title. Another little RRer marvel from Honda Racing ...
You're right except for one thing: the power figure was 16 PS - i.e., it was the rear wheel power. Crankshaft power was 18.8 PS @ 21,500 rpm, red line at 22,500 rpm.
Angry little gnat. At these high revs, with radical valve timing and cams.. these super high output 4 strokes begin to sound very much like 2 strokes. obviously a little tuning still to do.
This bike's engine had the highest specific output (bhp per litre) ever recorded for any naturally aspirated (not turbo or supercharged) four-stroke engine. Today's MotoGP and F1 units don't even get close. Honda were working on a 3-cylinder 50cc race motor when the decision was taken to drop out of the 50cc GP class. The 2-strokes won in the end but Honda held them off for a very long time.
@@gourishankar52 Yes, the book "Honda's Four-Stroke Race History" is still in print, you can order it from Rosedog Books, 701 Smithfield street, Pittsburgh, PA 15222. ISBN: 978-1-4349-8083-0. The price is $ 19.00.
@@gourishankar52 When I visited the Honda museum in Osaka some time ago, I asked Ozaki Mitsuo, the head of restoration about it, and he said that a 50 cc three cylinder was built, and underwent a 24 hour test on the dyno, but since Honda stopped their GP efforts, the project was not pursued. He didn't know what became of the engine.
When Ralph Bryan's was riding it at the IOM the rev limit was about 17 thou, when he finished the race the mechanics asked him what he was revving it to as they knew by the sound of it that it wasn't 17, he said 21 thousand odd. He told them that was what he had to do to keep up with the Suzukis so they altered the rev limit then to suit !
Wicked sounding little bike. I couldn't help but imagine having this engine on on an old Sears, Daimler Puch , 49cc Mo-ped, or something similar, and cruising around and someone on a larger, 80mph, top speed motorcycle, picking on me, which did happen, a couple of times, when I was a kid.
These little monsters were anything but fun to ride, as a narrow power band and minimal contact patch meant you had to keep "rowing" from gear to gear, continuously, to stay "on the boil". Add in the bumpy, often slick road courses of the era and you can see why Hugh Anderson and the other 50cc class riders were complaining. Note the bicycle-type rim brakes as well. Rotsaruck with stopping power on those. The FIM instituted a minimum 50kg weight limit for riders, forcing some of the tiny Japanese guys to carry a lead weight belt to qualify. The 125s were marginally better; when I rode Redman's ex-250 four-cylinder at Suzuka in 1968 I found it very steady and forgiving (except for the tires, which along with suspension were far behind the rest of the engineering). You can hear these tiny singles and twins at the IoM TT on old recordings from miles away, a jumpy nervous scream as they bounced from bump to bump. Honda even built a 3cyl 50 prototype, which they smuggled into Suzuka in the back seat of a taxi to evade motorcycle journalists. Never raced it though..
There are so many videos of classic Honda bikes being demonstrated in that same “parking lot” that I have to imagine it all happened on one hell of a demo day!
I love how Honda shows their realibility and their confiance by besides another companies they turn those historical things on to at least register it and keep it alive
Still the only motorsport category that’s affordable. Nobody understands why the 50cc class was abandoned. Just when I was 16! Officially the age that we’re allowed to ride 50s! SMH
+leopold klop This is not a matter of debate or opinion mate - it's a simple question of FACT. The fact is this is a four-stroke engine and you having a smoke theory won't make camshafts and valves vanish.
my 56 year old uncle phil had a honda cb50 back in his youth,if this mods and high revving was done to his bike.parts, pistons and coils etc will be all over the place
Engines are capable of producing so much more power than people realize. Road vehicle are limited so that engines can’t blow themselves within the warrantee period if people abuse them

They never showed the 50cc racing on TV But I find those races very enjoyable as well
Still the only motorsport category that’s affordable. Nobody understands why the 50cc class was abandoned. Just when I was 16! Officially the age that we’re allowed to ride 50s! SMH
Twin cylinder four stroke. What an engine.
+Hannu Mäkynen This sounds more like a 2-stroke in my ears...
+Berta Riise cause its a 2stroke
+MrProkiller98 No it's not mate. Jeez, look up Honda's racing history.
+MrProkiller98 not the two stroke years .this is 4 stroke all the way.
+leopold klop This is not a matter of debate or opinion mate - it's a simple question of FACT. The fact is this is a four-stroke engine and you having a smoke theory won't make camshafts and valves vanish.
my 56 year old uncle phil had a honda cb50 back in his youth,if this mods and high revving was done to his bike.parts, pistons and coils etc will be all over the place
3:12 this what I call a superbike sound
Engines are capable of producing so much more power than people realize. Road vehicle are limited so that engines can’t blow themselves within the warrantee period if people abuse them
Sangar suaranya😍

ちなみにですが、「スズキ」は試作で50ｃｃ」90度Ｖ型3気筒の2ストエンジンを造りましたが、ピーキーすぎて使い物にならず、結局お蔵入り（というか廃棄）になったそうです。レーサーか関係者が密かに部品を持ち帰り、「形だけ」は残っているというのを、某バイクの専門書で見ました。
Absolutely amazing! :)
あえて日本語で書かせていただきます
整備をする多数の方々のおかげで、ライダーは花道を歩けるのですね

Hola xd
8 valves in 50cc? Damn that's so tiny IWANNIT SO BAD
Over 30% more power than most average road legal 125cc bikes today.
22,000 rpm? Wow! In 1966?
Cool stuff, I like the fact, they used bicycle front brake on those...
いい音だ・・・
nice sound
お疲れ様です。素晴らしい！！
ありがとうございます！
2 cylinder 50cc?! The pistons must be the size of shot glasses.
Ramond Ferreal thimbles!
bore 32mm (1 3/8") stroke 29mm (1 3/16")
@@russelldawkins3408 No, bore 35.5 mm, stroke 25.14 mm.
At first you don't think much of that little motorcycle... then, it fires up! Wow!
How amazing the engineering in 1966
i was amaze by the video quality
bro the video is not from 1966.the bike does.jesus.
@@ting6161 Lol
Gotta be the most badass 50cc motor of all time.
The sound of Honda RC116 is amazing *_*
9 gears is not wierd.. kreidler made a 14 gears 50 cc racer once
lars kristensen kreidler with a "drie bakvoet"w
lars kristensen And Suzuki's 18 geared ;)
and suzuki even developed a V3 50 cc!!!!!!!!!!!! two stroke kriedler made one with a 12 speed
kreidler 12 gerabox
DETROIT !!!! Rode my Honda 50 mini motorcycle. It was oldest first built bike when I little kid in Detroit.
カブにこのエンジン積んでみたい(笑)
This had to be one of the most displacement to power ratio efficient engines ever.
You're quite right - 378 PS/L!
@FichDich InDemArsch show me a two stroke that has that power to liter of displacement ratio.
The power of dreams
The Motorcycle model was from 1966
The video footage was from 2012.
First of all before you all mock the video footage, read the description of the video.
pure magic........
I love they're using a Honda engine... to start the Honda engine.
beautiful sound
I saw not this specific one, but other racing bikes from that era and you cannot imagine how loud that thing is. Like seriously, when we passed near it, it was really blowing my fucking ears xDDD
4-STROKE ?
SOUNDS LIKE 2-STROKE ENGINE !
4 stroke+small displacement+high compression+high rpm=2 stroke
Just imagine racing that down the mountain to the Creg at that speed and hoping those brakes are going to slow you down sufficiently......
*パッと見フルカウルついてるチャリンコ*
Dream Fighter それw
50cc frickin awesome what a noise , best bike I ever heard was think z650 sounded similar like ripping metal
Moto gp 1900 50 cc, 12 Gear woww😎😎
No.... 250cc six cilinder 4 stroke
’車輪’ の大きさに「良き時代」を感じる
These sounds Last for Ever&Make you Realise What Fantastic Machinery there was& IS WOW
It is like a thai concept filipino here💓
14hp on a 50kg bike
Let's say the rider is about 85
the Total weight would be 135kg
so the power to weight ratio would be
around 280hp per ton on 20k rpms
that's pretty hardcore to be honest
its a four stroke that is music to my ears....
such is life it's a 2 stoke
ITS A FOUR STROKE TWIN CAMSHAFTS AND FOUR VALVES PER CYLINDER 16 BHP @ 21,500 rpm Honda RC116
Honda used only 4 stroke
AM990 Right so I guess the NS bikes they made were 4 strokes then?
Adam Dombrowski
That was the first 2 stroke they made. They were forced by the restrictions introduced in Regulation, that forbade engines with more than 4 cylinders
凄く楽しそうですね！
Motor astrea gua berarti lebih kenceng nihhh :D
Astrea 100 cc, max 8.000 rpm, top speed 130 kmph
Ini motor RC116 walau cuma 50 cc, tapi max rpm 21.500, top speed 160an kmph. Berani adu? 😁
@@dewaprama astrea apaan sampe 130 wkwk
@@dewaprama atrea mah 100 juga susah
@@dewaprama buset, Tiger aja mentok 130, dulu pernah punya Blade cuman 95. Astrea nya om ku dulu 80 aja udah susah.
Ya CC besar bukan berarti power juga besar, walau 50cc tp power nya 16hp...udah setara Tiger tp jauh lebih ringan.
@@dewaprama 130km maksudnya numpang bak pick up

乗ってみたい！
14PS from 50cc makes for 280PS per litre! That's insane!
The actual horsepower was 16 PS at the rear wheel, 18.8 PS at the crankshaft at 21,500 rpm.
