    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.

    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.
