Zongshen ZS125 or CG125. Before I ran the 200cc water cooled engine in my Gomoto GTR125, this 125cc engine was the original. The 125 has good top end power for its displacement, however, it lacks bottom end torque. Very good engine for beginner riders, as it is not overpowered. If you want reliability and power, I recommend the 200cc engine as it carries good speed with the right sprocket ratio, it produces both good torque and horsepower, also parts like the clutch, transmission and conrod big end bearing last longer than the 250cc engine. In the 250cc engine, the clutch plates wear out faster, 3rd and 5th gear get damaged from the torque as well as the conrod big end bearing wears out faster due engine power. You must remember, these engines are clones of the original honda CG125 design, the fact that they have made various cylinder capacities from a 125cc design is fantastic.

Info on these engines: Originally, a honda design. Honda CG125's were developed from the CB125. Instead of having an OHC (Overhead Cam) design, it was designed by honda to use an OHV or Pushrod design for third-world markets. The CB-engine apparently had issues regarding camshaft bearings if I recall, so to increase reliability was to pursue an OHV design. This engine became popular for select markets and eventually copies of these engines, most notably chinese copies, started to roll out

Engines are amazing. So many parts that all work together and are made accurately enough to do so. Great video.

fajnie wreszcie pracują przy stole wie piachu sie nie nasypie . dobra robota👍😉

Yo amo las motos benditos Los que fabrican motos dios los bendiga por siempre!

Real respect to these guys!

That was just AWESOME. Thank you for the video. Helps me get an idea of all my engines components

Muito top essa montagem gostei

I am Nigeria I love your work, I am into motorcycle engineering I need a job

Simplesmente 💯 sacional valeuuuuuuuu sempre em frente

Parabéns pelo Belo trabalho!! Tenho duas moto com esse motor muito bom, um esta com 30 anos o outro com 25 os dois nunca foram abertos, somente regulagem de válvulas!!

Love how efficiently these are made very satisfying

جزاك الله خيرا اخي الحبيب وصلي الله وسلم وبارك على سيدنا محمد وعلى اله وصحبه اجمعين

Excelente , muy bacano ver todo el proceso de ensamblaje , gracias a quien subió el vídeo 👍

It is very satisfying to watch people who are so skilled and seem to actually enjoy their job. I have never ridden one, but I’ll bet the Metro motorcycles are a joy to ride on.

EXELENTE TRABAJO BUENOS EMPLEADOS INDIA Y PAQUISTAN SON BUENOS EN TODO TIPO DE TRABAJOS Y BUENOS OPETADORES DE MACHINE SHOP.

excelente trabalho Deua abençoe 🙏🙏🙏

Belo trabalho.

Incrível a inteligência humana.

I heard about metro bikes a few years ago and got myself one. Blody hell are they robust! But they have to, if you take a closer look at where they actually drive around. In that video, you can see that they use valve rods instead of timing chains. Open up the valve head, cange the rods and close it.. finished. A timing chain is more efficient but not this easy and cheap to replace. Aaaand you get a nice retro looking bike, like a 70ish Honda

nice job 👍👏👍

Un motor ohv buenos con sus respectivos cuidados 👏

Good work❤❤❤

Хорошее пособие по сборке 125-ки)

Very interesting & satisfying video. I like the process & team work that are involved to manufacture moter cycle engine. Well done. Keep sharing 👍😊

感謝分享

Esses são os melhores motores que a Honda já fez isso na minha opinião ok

الله يعطيكم الصحة ❤👍👍👍

Good job, guys!

Ótima montagem

Прям рекламное видео - все рабочие чистые, причесаные, одеты в новое, крика дикого в цеху нет, но снятый в конце типок в шортах и шлепках на босуногу попалил всю контору!🤣🤣🤣

Excelente video excelente

Ótimo trabalho

Passei 11 anos com um motor desse de vareta. Muito bom. Econômico, forte e não quebra fácil. Agora estou no 250cc da Yamaha que é outra lenda.

Tive varias moto honda com esse motor que na verdade e copia muito bom e eficiente.

Mantap sekali mas semoga bermanfaat buat ku

WOW ! I've been a Honda mecano for decades , it would take me hours to reassemble that 125 Honda clone . Respect for these guys , they should be hired for F1 pit stops - under 1.5 sec , promised. Amazing.

We have these in 150,,,,175,,,200,,,230 and 250cc in Jamaica their the best they can take rev and easy to fix😂🙏👍👍👍👍👍👍👍🇯🇲,

Video của bạn rất hay ❤️❤️🔔

Nice video 👍👍👍

Good job bro 🙏😇

Lắp ráp quá tuyệt vời

parabens pelo trabalho

جاااان❤🔥

a transfer cart or a rail hoist from the assembly station, to the air leak and oil filling bench, would be a more than essential idea, the operator could be injured by dropping the engine on its feet

Creo debe lindo y satisfactorio de arma y desarmar y arma tu propio motor

Super sir. இளையதலைமுறை பார்க்க வேண்டிய வீடியோ.whatsapp, face book னு time அ waste பண்ணாம உங்கள் வளர்ச்சிக்கு அறிவியல் முன்னேற்றத்தை பயன்படுத்துங்கள் உங்களுக்கான அங்கீகாரம் காத்துக்கொண்டு இருக்கிறது

great filming and editing

Boa. Rapaziada. Obrigado. 👋👋👋

دیکھ کے بہت خوشی ہوئی یارا پاکستان میں بھی موٹر سائیکل کے انجن بن رہے ہیں۔

Parabéns pelo trabalho isso é muito complexo de fazer msm sendo simples

buen dia, quisiera saber por que meten el motor en una tina con agua....y le faltaron las tapas del lado izquierdo...!!!!

Hal tersulit yang saya pelajari dari kursus bengkel motor

I like the way they check the end float on all the shafts. If it's to tight it'll loosen up and if to loose that rattle give it character. At least there not building it in the dirt.

Fine job.

Nice

Hola, buen video. Qué líquido es en el que sumergen el motor? No se le mete dentro?.

定期的に見ちゃう
