The Yamaha RT1 Standard piston, model number 284-11631-00, is a crucial component for the two-stroke, air-cooled, 125cc engine used in various Yamaha motorcycles from the late 1960s and early 1970s. This piston, specifically identified as 284-11631-00-96, is engineered for smooth engine operation and optimal power delivery.
Made of high-quality aluminum alloy, this piston boasts a forged design. Forged pistons offer significantly increased strength and durability compared to their cast counterparts. Each piston is meticulously crafted through a series of press operations. This process ensures a consistent shape and size, enabling a perfect fit within the engine's cylinder.
An essential feature of this piston is its ring grooves. They accommodate piston rings responsible for sealing the combustion chamber and reducing exhaust gas leakage. Additionally, the engine's overall performance and efficiency are improved thanks to the rings preventing the loss of compression and reducing the emission of harmful gases.
The piston crown has a dome shape design, which enhances engine power and improves combustion efficiency. The skirt has a uniform wall thickness for even heat distribution and minimized deformations. Moreover, the piston has a mirror finish on its outside surface, ensuring a hassle-free installation in the cylinder.
The piston pin bore diameter is appropriately sized to fit securely within the connecting rod's crankpin. The piston pin is held in place by a retainer accompanied by a compression ring and oil seal. These components further secure the piston pin and promote engine longevity.
Designed for the specific requirements of specific 1970 - 1971 Yamaha motorcycles, the 284-11631-00-96 piston is a mandatory upgrade or replacement for any motorcycle enthusiasts aiming to achieve peak performance, reliability, and longevity from their classic Yamaha two-stroke engines.
