I installed in a 2010 Barton Fighter moped. After mounting the moped clearly came alive, it became very sprightly, the top speed also increased. After starting from first gear it can sweep the wheel, and after releasing the clutch faster it stands on the wheel, also when shifting to second gear the front end likes to lift gently. Overall, for this price I can confidently recommend this cylinder to everyone. I recommend 100%

I ordered a crankcase for a Junak 902 - although it is listed as "fits to" on the item page, unfortunately it is not a perfect fit. Unlike the original, it does not have an input for the shift sensor cable.

I have a Junak 901,I bought this kit because the motorcycle was already quite weak. I did the assembly for the first time, and it took me some time. So far I'm lapping , and I have no problem. I think Moretti products , are good parts and recommend.

The 50 cm³ cylinder for the 139FMB 4-stroke engine is an excellent choice for anyone looking for a reliable and durable replacement or upgrade for their engine. The workmanship is precise and the fit is perfect - installation went smoothly. After installation, the engine runs perfectly again, with smooth running and good performance. The cooling fins ensure efficient heat dissipation, which increases durability. A particularly positive feature is the high-quality material, which promises a long service life. All in all, a top product with a great price-performance ratio! A clear purchase recommendation for anyone who wants to get their 139FMB engine back in top form. ⭐⭐⭐⭐⭐

Product arrived quickly and in full with fast processing and no complications. The price is fair and also very good value for the good quality. Shipping costs are also not as high as with other suppliers. As stated, the parts fit perfectly for my Romet Router WS 50 with four-stroke. I have installed everything new and everything is running great, just as I had hoped. I always order spare parts for my moped here and have never been disappointed.

Very good build quality. The head with larger valves to this plus the replacement of the main nozzle in the carburetor gives incredible power. And if you replace the gearbox with more teeth in the engine it flies like a storm. 2 times faster and much more powerful. I sincerely recommend. I have taken a lot from this store and everything great.

the cylinder itself is great and the piston all the seals and piston rings . it's supposed to be a plug and go cylinder . NOT I have a jawu betka/kentoya twinshot and need to buy a new head because the original camshaft is not enough and need to adjust the valve .

The cylinder fits perfectly to the engine 139FMB, the moped after such tuning laughs beyond recognition, I wanted to emphasize that I did not replace the gasser, it is the original from the fifty, only the nozzle replaced with a larger + head and everything runs perfectly.

As the only product I have a negative opinion because the quality of the thread in the nuts purchased was tragic both in terms of its appearance and the internal diameter on which the thread was made . I did not install them on the motorcycle .

Good quality nickel, long-lasting. I recommend it. I tatolized 2690 km and it turns nickel no particular problem. Just alignment for slightly hard mounting, but nothing else to complain about.
