Review YAMAHA Left Cylinder Jug fits RD125 1975

The Yamaha RD125 left cylinder jug, model number 396-11311-01, is a crucial component of the classic 1975 Yamaha RD125 motorcycle engine. This jug is specifically designed to house the left cylinder, which plays a significant role in the two-stroke engine's combustion process.

Constructed from high-quality aluminum alloy, this cylinder jug boasts a finned design that efficiently dissipates heat generated during engine operation. The cylinder bore measures 57.5 millimeters in diameter and 54.5 millimeters in stroke length. The jug's exterior is finished with a durable, matte black powder coat that not only enhances the engine's aesthetic appeal but also provides an added layer of protection against corrosion.

The left cylinder jug is designed to work seamlessly with the accompanying right cylinder jug (sold separately), as well as other essential engine components such as the crankshaft, piston, and connecting rod. The jug features an integral water jacket that ensures efficient cooling and maintains optimal engine temperature for consistent performance.

This particular Yamaha RD125 left cylinder jug is in excellent condition, having undergone thorough inspection and reconditioning by our skilled technicians. Each cylinder jug is meticulously cleaned and inspected for any signs of cracks, leaks, or other damage before being sold. Additionally, we ensure that all O-rings and gaskets are in pristine condition to guarantee a proper seal and prevent any unwanted leaks.

In summary, the Yamaha 396-11311-01 1975 RD125 left cylinder jug is a high-performance, durable, and essential component for any serious Yamaha RD125 motorcycle enthusiast or collector. Its finned design, aluminum alloy construction, and efficient cooling capabilities make it a valuable addition to any vintage motorcycle engine.
