Ricordo una in particolare aveva un motore derivato Honda, preparato da un meccanico Italiano ed era un 175cc.2 T ed aveva 12 marce. Erano state aggiunte parecchie marce in più visto che facevano fare di durata, con rettilinei molto lunghi. Io sono nato nel 1968,ed ho avuto la fortuna di vedere e guidare queste moto. Ma non sono mai riuscito a trovare dove facevano queste gare in Italia, non andava nell'isola di Man. Se qualche appassionato, più esperto di me, sa dirmi qualcosa a riguardo, ne sono felice.

This bike is so beautiful in get tears in my eyes, this masterpiece is something all Japanese people should be very proud of, a true national treasure.
That bike is a work of art... Honda's ultimate answer to the two stroke resurrection. Sad that mechanical beauty of bikes is swapped for electronic gizmos in current era! Long live the RC166, Long live Mike 'The Bike' :)
What an honour to be allowed to work on this magnificent machine .Real mechanics .I remember when these machines appeared first way back when .We were all just blown away with the technology.
I was on the Island the first time the Honda 6 raced. Wow, what a culture shock, I was used to hearing singles and twins, to hear the scream of that 6 cylinder was something totally new.
I was in Mosport in I think 1967 when anyone could get into the pits and saw the 5 cylinder 125 cc. The engine was like a piece of jewelry with tiny little carbs. The sound of it was incredible as it didnt sound like an engine at all. Just a incredible shriek. It never idled they just kept bliping the throttle.
The difference was i believe the British Motorcycle industry at that time was run by Finance people. Soichiro Honda was an Engineer. As I understand it in the 1950's BSA had a Drawing Office and a Development Dept., but not a Design Engineering group. The Development Dept. evolved the legendary Gold Stars. BSA Management failed to see that ALL manufacturers live or die by their designs and the BSA designs of the1960's still had parts designed back in the 1920's and 30's. They had Doug Hele, but he was hopelessly under resourced. Finally BSA employed Stylists at Umberslade Hall to design their motorcycles, some of the worst BSA designs ever. In 1968 BSA Management told the press that they would worry about the Japanese when they built a "real" motorcycle of 500 to 650cc. In 1969 Honda introduced the 750cc single overhead cam, front disc braked, four. Press of the day predicted sales of "50" a year. In its first year it outsold the BSA and Triumph 750 triples put together. The BSA/Triumph triples took four years to get into production. The Honda 750 was done from scratch in nine months, lead by Yoshido Harada, Senior Engineer. Soichiro Honda's 250cc six was designed when he was sixty years old. It was and still is a brilliant piece of Engineering Design.
In the 1930's the British had a water-cooled 4 valve DOHC engine, probably the best on Earth ~ RR Merlin, so we had the technology. In the early 50's Norton was working on a 4 cyl GP Bike & BSA had a promising 250 twin ~ all quashed by Managment.
Formula One eat your heart out. This incredible piece of engineering/ instrument making was designed and built in the 1960’s. Their introduction into cars was in around the same time with a 1.5 cc v16 and it also sounded beautiful , driven by no less than John Surtees.
Can't have done; Surtees was a Ferrari-contracted driver at the time Honda entered F1 (1964+). When he did go to Honda (1966) it was the 3 litre era and they had a V12...they never made a 16 cylinder.
+Jock McComisky And to think i get all excited to just hear a Suzuki super six and early aircooled Yamaha 2 stroke flash past that very point at the classic/mgp oh for a time machine
I can only imagine how this engine could evolve if it was made today with modern building and technology. 250cc is about 1 cup. 250cc divided into 6 is around 41.66cc per cylinder or 1.4 ounces. I am impressed that someone was able to make an engine that small with 4 valves per cylinder.
So many tiny parts and pieces. I would like to see an article about the people who envisioned this and how many failures they had until they got it right. Thanks for posting this.
was lucky enough to see Mike Hailwood ride one in anger at Oulton Park in the 1960s, it was a still day and you could hear the bike all the way round the track; incredible!
@@saifuddinudin1748 Exactly in what you say. The engineering was from an alien world at the time and quite frankly still is. I remember going to a motorcycle show in the sixties and being amazed by the finished welding of the frames, it was like there was no weld at all. Incredible engineers. The Japanese use a process in production, called Kaizen, meaning continues improvement and boy is it working in that country, hence being the third largest economic country in the world.
Loved my old CB400F4. What a masterpiece of a 4 cylinder 400 cc motor. It was so small it lived in the living room when I was not using it. If only Honda came out with a duplicate of that today! A perfect one would be a 4 cylinder motor, 400cc, single sided swing arm, cafe fairing, light weight, & modern suspension. Oh my!
They were still making 400cc 4 cylinder bikes right through the 90s, All the Japanese bike factorys did due to licensing laws over there. I had a Honda RVF400 a V4 400cc with HRC kit ECU, airbox, and jet kit it was a quick little bike.
@@uhtred7860 I just looked at a picture of your RVF400, that is one sweet looking bike. If Honda made that today, it would look good in my living room again when not in use!
Good camera work, the mechanics were little unprepared but performed well under pressure Nice motor,it borrows more from aircraft engine construction than automotive engines of that era. Thanks for posting.
Mr Honda certainly put his heart into these beautiful machines, very nice to see the reactions from the audience. What was the purpose of this disassembly? A practical engineering lesson for students maybe?
This motorcycle is beautifully designed, machined and assembled. Honda I am sure are very proud of this motorcycle and engine, for it simply is a work of modern art. For this and many other engines Honda must be able to lay claim to being the top builder and manufacturer.

Couldn't imagine a 21st century Road car coming apart as easily and completely without dramas and breakages, goes to show what real engineering is and not cost cutting.
If anyone asks you how the Japanese motorcycle industry jumped to the head of the line, ahead of the older and more established motorcycle companies, show them this video. There's no magic here, no tricks or rules short-cuts, just solid design and relentless individual effort.
There's also the fact that Soichiro was a relentlessly-demanding leader. I read that an engineer once brought him a small prototype part, and Mr. Honda didn't approve. He actually threw the part at the engineer.
HideTunedEngines Also people should remember that the Honda CB 750 wasn't far away using some of the technology as a basis seen here. The 750 hit the show room in 1969 Even prior they had a CB 450 DOHC & torsion bar valve springs & could just about stay with a triumph 650. I bought the second model the CB 750 K1 in 1971. It had a single throttle cable to a shaft that linked all 4 carbs thus allowing synchronization to be maintained. The 1st model had a cable to each carb. In 10 years they made 400,000 of these bikes in various models. Larger Japanese bikes were superior in electrics & standard features like disc brake & electric start & large accurate speedo's & tacho's. The UK bike Industry was in already in financial trouble, the CB 750 & smaller capacity models were the "Nail In The Coffin" for them. They have come back somewhat but can never challenge the Japanese bike manufacturing juggernaut. Japanese machines have dominated GP racing for more than 50 years. On the 250 six it only has 3 sets of points. The points operate off the crank & so rotate at crankshaft speed. 1 set of points fires 2 plugs, each one sparking alternatively on the power stroke & then the exhaust stroke . Very impressive that points can still function at 18,000 RPM. The CB 750 was similar with 2 sets of points used for 4 cylinders. Over time points were replaced with electronic ignition & air cooling was replaced with liquid cooling. The smaller capacities @ 50 cc had 2 pistons & the 125 cc had 5 pistons but all with 4 tiny valves per cylinder. I remember a motorcycle paper in the 1960's having a feature about valve timing on the 50 cc machine, it revved to 22,500 rpm & the 125 to 21,500 due to the x3 120 degree & x 2 180 crank angles? The 50 cc had a power output of 320 BHP per litre, sensational for the 60's & even still very impressive today.
Notice on the pistons only 1 compression ring, the idea being less friction. This was standard Honda racing build for all capacities at that time. I saw a comment the other day that the larger capacity 1960's replicas used these days have 2 compression rings fitted to their pistons. Probably all part of building in more reliability & so extending the rebuild period ?
@@hughmoore810 I'd say that your instinct is right on the money. After all, the race versions were as high-strung as they'd dare to get away with, and certainly a lot of engines didn't last to the finish line. The motors were detuned & modded for street use (including the extra ring) so they'd hold their fluids & compression & last for many years, at the expense of a few horsepower. The street engines were made to be more tractable, too. Most of the race versions had a whopping power peak somewhere in the upper half of the powerband, which many street riders would find difficult to meter out.
I WISH THIS HAD SUBTITLES AT THE VERY LEAST.... Would make this thoroughly enjoyable if I knew what they were saying as I have always been curious about these engines. What kind of a show IS THIS in Japan anyway...strange crowd for a teardown of this magnitude. Messing up those pristine fasteners and such... Oh well... Honda has the money
Engineering art which the Japanese technicians worship as a God-like work of mechanic genius. I built a 1/8 scale model in the late 60's. I think it was Tamiya. I think it got badly broken during a move. I am going to build another kit if I can get it. I can't afford the full size one as it may be over 10 million dollars?
I read somewhere that an F1 team were asked to refurbish one of these. After re assembly they said that some components & the crankcase oil galleries were made by unknown metallurgical & manufacturing processes that Honda San took to the grave.
And after Mr Soichiro Honda was safe in his grave the new heads of Honda gave us the one thing he said they never would ! on You Tube HONDA GRRR how he must be "spinning" at a very high rate maybe even 22k rpm ?
The crazy cam timing necessary to get it to rev to 20k is confirmed by the massive dome on the pistons revealed at the end. The inlet valve would be shutting with the piston about half way up the bore.
quite a challange getting a good static comp. number under 50cc a hole! They probably could have got a few thou more out of it by moving the cam lower and eliminating those bulky followers.
@@eprocess3248 Problem is, if they eliminated the followers, the side forces on the valve stem would snap it off or bend it. The followers direct the force of the cam directly to the top of the valve stem. I'd like to see what they use for a jig to get all 6 of those tiny pistons back into the cylinder block without breaking one of those microscopic rings!😮 They obviously can't do it from the top, since the cylinder block is an integral part of the top half of the whole engine..
I worked for Honda as a motorcycle mechanic and they wanted me to wear white coveralls too. I said i will only if you pay for the drycleaning/ washing.
Even with the knowledge of now this machine remains a piece of superlative engineering. I still have a photo of myself as a young boy in the sixties, I'm looking in the camera lens. I'm wearing a T-shirt with a Honda RC166 image printed on it. I have this huge smile on my face, certainly not aware of the damage in the European enigineering camps after the Gods of Honda send the RC166 to planet earth.
2:38 Dude in the first-row (second from right) didn't even flinch. Check for a pulse. I'm sitting at home watching on youtube and even I shat my pants!
Amazing, strange to think that at that time we were still trying to wring another 1 BHP out of a 500 Manx. Virtually nothing had changed in 20 years then this.
Notice the single piece connecting rods.... That means a multi-piece crank completely pressed together. And they had to balance all the multi pieces with 6 connecting rods. The jigs must have been a piece of art. Watching the disassembly I saw so many CBX type of comparisons. The 4 piece cam shafts that fit together to form 2 cams with oldem style connectors. The offset stator with the ignition attached to the stator. The CBX uses electronic ignition but the points are replaced by the electronic setup. The cams are a piece of art and notice the lack of cam chains just like on VFR-R versions.
Look at Allen Millyard build video of his Kawaski 6 and his replica of that engine if you want to know how the crankshaft is made ua-cam.com/video/uW2YFNDjN_o/v-deo.html
@@sideshowbob5237 That's exactly what I thought!! They almost have to have some sort of special jig to get everything lined up with the bottom of the bores or they would be breaking those microscopic rings as soon as something got off-center. Even with tapered lead-ins, it would be almost impossible to get them started into the bores.🤔 This thing is a work of art!!😁
Awesome《☆》The little valves look like golf tees. I have about the same model Snap On tool box but it's nowhere near as impressive as that crankshapto🤠☻🤠
I suppose the small intake valves are meant to increase flow velocity & help to more-thoroughly mix the charge prior to combustion. I didn't think they'd be THAT small, though! Hoepka & Woods will be sniffing around the shop before long.
@@randolphpatterson5061 You're completely wrong, of course! Valve size was 16.5 x 2 inlet, 14 x 2 on exhaust. The valves were the largest size that could fit!
@@davidkenyon927 I think the RC-166 only held about 1 1/2 - 2 quarts of oil, max. They used castor oil back in the day, which degraded pretty quickly, plus with the amount of blow-by that these engines had, the oil got fouled up in a hurry.😉
Exactly the dohc cams were so precise, driven from a perfect crank, which gave induction and exhaust to be so precise and top it all no cad machines to draw it. Just a slide rule and drawing board and of course brilliant design engineering 👏👏👏👏👏👏

Yes, if you are working on a Honda motorcycle (especially the engine) and the parts aren't just sliding together, stop! You are doing something wrong.

Also people should remember that the Honda CB 750 wasn't far away using some of the technology as a basis seen here. The 750 hit the show room in 1969
Even prior they had a CB 450 DOHC & torsion bar valve springs & could just about stay with a triumph 650. I bought the second model the CB 750 K1 in 1971.

The smaller capacities @ 50 cc had 2 pistons & the 125 cc had 5 pistons but all with 4 tiny valves per cylinder. I remember a motorcycle paper in the 1960's having a feature about valve timing on the 50 cc machine, it revved to 22,500 rpm & the 125 to 21,500 due to the x3 120 degree & x 2 180 crank angles? The 50 cc had a power output of 320 BHP per litre, sensational for the 60's & even still very impressive today.
Notice on the pistons only 1 compression ring, the idea being less friction. This was standard Honda racing build for all capacities at that time. I saw a comment the other day that the larger capacity 1960's replicas used these days have 2 compression rings fitted to their pistons. Probably all part of building in more reliability & so extending the rebuild period ?
@@hughmoore810 I'd say that your instinct is right on the money. After all, the race versions were as high-strung as they'd dare to get away with, and certainly a lot of engines didn't last to the finish line. The motors were detuned & modded for street use (including the extra ring) so they'd hold their fluids & compression & last for many years, at the expense of a few horsepower. The street engines were made to be more tractable, too. Most of the race versions had a whopping power peak somewhere in the upper half of the powerband, which many street riders would find difficult to meter out.
According to Japanese info, there was at least one 250 six with transistor ignition.
女性のナレーターが、「タンクが！タンクが外れました！」とか「マフラーが！マフラーが外れました！」とか、別になんら感激するような場面でないところで、いちいち感極まったような言い方。その感情表現の不自然さに違和感がありすぎて、作業を楽しく見れない。冷めた返事をする技術者の態度が印象的。
I WISH THIS HAD SUBTITLES AT THE VERY LEAST.... Would make this thoroughly enjoyable if I knew what they were saying as I have always been curious about these engines. What kind of a show IS THIS in Japan anyway...strange crowd for a teardown of this magnitude. Messing up those pristine fasteners and such... Oh well... Honda has the money
Engineering art which the Japanese technicians worship as a God-like work of mechanic genius. I built a 1/8 scale model in the late 60's. I think it was Tamiya. I think it got badly broken during a move. I am going to build another kit if I can get it. I can't afford the full size one as it may be over 10 million dollars?
とんでもない番組だなｗマニアック過ぎて堪らん
ヤバ！
これだけ小さくて精密なパーツを50年以上前に作れてた事が凄過ぎです。
今現在、CADCAM、マシニングを使って高精度な部品を作る事が出来るけど、その当時はって考えるととてつもない精度を要求された事と思います。でもそのようなパーツを作る日本人はやっぱり凄いとしか言えないです。
"Monster bike from Honda"😂😂😂
Absolutely beautiful machine!! Incredible design. JAPAN, HONDA , all good! 😃👍💞⛩️🗾🗻
I read somewhere that an F1 team were asked to refurbish one of these. After re assembly they said that some components & the crankcase oil galleries were made by unknown metallurgical & manufacturing processes that Honda San took to the grave.
And after Mr Soichiro Honda was safe in his grave the new heads of Honda
gave us the one thing he said they never would ! on You Tube HONDA GRRR
how he must be "spinning" at a very high rate maybe even 22k rpm ?
Omg the sound. Rivals Yamaha grand pianos
The crazy cam timing necessary to get it to rev to 20k is confirmed by the massive dome on the pistons revealed at the end. The inlet valve would be shutting with the piston about half way up the bore.
quite a challange getting a good static comp. number under 50cc a hole! They probably could have got a few thou more out of it by moving the cam lower and eliminating those bulky followers.
@@eprocess3248 Problem is, if they eliminated the followers, the side forces on the valve stem would snap it off or bend it. The followers direct the force of the cam directly to the top of the valve stem. I'd like to see what they use for a jig to get all 6 of those tiny pistons back into the cylinder block without breaking one of those microscopic rings!😮 They obviously can't do it from the top, since the cylinder block is an integral part of the top half of the whole engine..
Valve timing: IO/IC 30/30, EO/EC 40/40. Read my book "Honda's Four-Stroke Race History 1954 ~ 1981".
I worked for Honda as a motorcycle mechanic and they wanted me to wear white coveralls too. I said i will only if you pay for the drycleaning/ washing.

私が尊敬してやまない偉人。技術者だけでなく人間性も素晴らしく夢を追いかけ実現させる事の素晴しさを教わりました。
The power of dreams 好きな言葉です。
Even with the knowledge of now this machine remains a piece of superlative engineering. I still have a photo of myself as a young boy in the sixties, I'm looking in the camera lens. I'm wearing a T-shirt with a Honda RC166 image printed on it. I have this huge smile on my face, certainly not aware of the damage in the European enigineering camps after the Gods of Honda send the RC166 to planet earth.
It isn't believed that it's a machine before more than 50 years. A wonderful performance.
日本人の誇り‼️たかがレースじゃない。日本🇯🇵が世界に名乗りを上げていく。本田宗一郎氏、またその仲間に感謝🙆♂️‼️
Una maravilla de motor con mucha tecnología para su época. La voz de la mujer, simplemente insoportable.
2:38 Dude in the first-row (second from right) didn't even flinch. Check for a pulse. I'm sitting at home watching on youtube and even I shat my pants!
Amazing, strange to think that at that time we were still trying to wring another 1 BHP out of a 500 Manx. Virtually nothing had changed in 20 years then this.
これは凄すぎる！これと同じもの作れるメーカあるのでしょうか？、今のホンダ技術者でも無理なのでは？機械工学の結晶と思えるくらいメカニカル。当時のホンダは凄すぎる！
Notice the single piece connecting rods.... That means a multi-piece crank completely pressed together. And they had to balance all the multi pieces with 6 connecting rods. The jigs must have been a piece of art. Watching the disassembly I saw so many CBX type of comparisons. The 4 piece cam shafts that fit together to form 2 cams with oldem style connectors. The offset stator with the ignition attached to the stator. The CBX uses electronic ignition but the points are replaced by the electronic setup. The cams are a piece of art and notice the lack of cam chains just like on
VFR-R versions.
Yes one piece con-rods - which begs the question, how the hell did they get the rings to go into the bores.
Look at Allen Millyard build video of his Kawaski 6 and his replica of that engine if you want to know how the crankshaft is made

@@sideshowbob5237 That's exactly what I thought!! They almost have to have some sort of special jig to get everything lined up with the bottom of the bores or they would be breaking those microscopic rings as soon as something got off-center. Even with tapered lead-ins, it would be almost impossible to get them started into the bores.🤔 This thing is a work of art!!😁
Que país incrível, parabéns pela dedicação
F1, honda, could we have a word with you fellers
Thanks for sharing!
Once I asked Jim Redman about the RC166. He looked at me and said: It was a beast!
Of course it was and most modern day racing bikes still are, which is where the jockey comes in to play
I’d give a leg to ride that bike , a 6 in line 250cc is beyond insane engineering
BEAUTIFUL DONE YOU GUYS.😊🤗🇷🇺
Especialy him with that screwdriver and the mallet.x
Superb piece of Japanese engineering.
Real monster. I love Honda.
Did anyone notice the tacho was moving from the torque of the needle revving to over 10000000000000rpms
The 5 Cyl 125 2 stroke is one of my favourite engines, 35hp 8 speed 20.500 Rpm!! Simply science
That was a four stroke, of course! Read my book "Honda's For-Stroke Race History 1954 ~ 1981".
Awesome《☆》The little valves look like golf tees. I have about the same model Snap On tool box but it's nowhere near as impressive as that crankshapto🤠☻🤠
I suppose the small intake valves are meant to increase flow velocity & help to more-thoroughly mix the charge prior to combustion. I didn't think they'd be THAT small, though! Hoepka & Woods will be sniffing around the shop before long.
@@randolphpatterson5061 《☆》Also lighter mass = higher rpm capability with less chance of valve floating :*: That crankachapto tho🤓🤠☻🤠
@@randolphpatterson5061 You're completely wrong, of course! Valve size was 16.5 x 2 inlet, 14 x 2 on exhaust. The valves were the largest size that could fit!
The engine oil looks like it's been in there since 1966!
Not much came out either!!
@@davidkenyon927 I think the RC-166 only held about 1 1/2 - 2 quarts of oil, max. They used castor oil back in the day, which degraded pretty quickly, plus with the amount of blow-by that these engines had, the oil got fouled up in a hurry.😉
So beautifull of masterpiece.. God i dreaming to own this bike 😍😍😍
Hope dreams come ！💘
ポイント点火だったのか！ ３ポイントで18000回転凄い。
もっとバイク知っている女子アナを雇って欲しかったな〜って生で見てた時思った！！
NHKアナウンサーだと無理なんでしょうね。観覧側に回ってしまっているゲストの数を減らしてでも工学的な知見のある方であればもっと素敵な番組になったかもしれませんね。
Gracias por su video más que excelente saludos cordiales desde Chaco Argentina
Beautiful machine
👍 I think so，too ！
Beautiful
me from Malaysia love this video❤
Could someone do an english translation for this video PLEASE??
S'est juste magique 💕💕, pour moi la meilleure pour faire FACE AU AGUSTINI 💖😍
Japonais des génies imbattable !!!
great to watch... staggering to think they were using points for the ignition! 18k, wow
Exactly the dohc cams were so precise, driven from a perfect crank, which gave induction and exhaust to be so precise and top it all no cad machines to draw it. Just a slide rule and drawing board and of course brilliant design engineering 👏👏👏👏👏👏
