YX100-2 Piston: High-Torque Balanced Engine Part for Motorcycle & Tricycle

Introduction: The Versatile Power Core of Reliable Engine Parts

The Piston is the dynamic heartbeat of any combustion engine, translating fuel energy into robust mechanical torque that balances performance, durability, and efficiency. For those seeking a well-rounded, high-torque engine parts solution that excels in both work and everyday use, the YX100-2 piston stands as an industry-trusted choice. Meticulously engineered to meet the diverse demands of two-wheel and three-wheel vehicles, this piston seamlessly integrates with motorcycle parts and tricycle parts systems, catering to professional mechanics, commercial operators, rural users, and small business owners who prioritize power, longevity, and cost-effectiveness. Whether you’re repairing a heavy-load tricycle, maintaining a rugged commuter motorcycle, or upgrading an engine for mixed-use scenarios, the YX100-2 piston delivers uncompromising reliability—solidifying its status as a must-have component in the global engine parts market.

Product Overview: YX100-2 Piston – Engineered for Torque & Versatility

Model Identification: YX100-2 Piston

The YX100-2 piston is a specialized high-torque balanced model crafted with OEM-grade precision, bearing the distinct YX100-2 designation that signifies its adherence to strict quality and compatibility standards. Unlike one-dimensional alternatives that sacrifice efficiency for power (or vice versa), this piston is engineered to fit YX100-2 engine platforms and compatible variants, ensuring a seamless replacement or upgrade for worn components. Its model-specific design guarantees perfect integration with existing motorcycle parts and tricycle parts without modifications, saving installation time and reducing fitment risks—an essential advantage for both professional workshops and DIY enthusiasts seeking hassle-free repairs.

Application Scope: Beyond Motorcycle Parts

While the YX100-2 piston excels as a premium motorcycle parts component for rugged commuter and utility motorcycles, its versatility extends to the tricycle parts sector and multi-purpose small-engine applications. It is specifically optimized for YX100-2-powered heavy-cargo tricycles, agricultural utility vehicles, off-road commuters, and rural delivery vehicles operating in diverse conditions—from muddy farm trails and uneven rural roads to daily urban commutes and short-haul delivery routes. This broad applicability makes it an invaluable asset for inventory managers and small business owners, as it streamlines parts sourcing for vehicles that transition between work and everyday use. Whether powering a passenger-cargo motorcycle or a farm utility tricycle, the YX100-2 piston maintains exceptional performance across all scenarios.

Key Specifications: Precision Dimensions for Balanced High-Torque Performance

Cylinder-Centric Dimensions

CYL DIA: 53 – Oversized Bore for Maximum Torque Output

With a cylinder diameter (CYL DIA) of 53mm—slightly larger than standard 52.4mm pistons—the YX100-2 piston is engineered to maximize combustion volume and torque density. This precise oversized bore ensures optimal compression of the fuel-air mixture, translating to robust low-end torque for heavy-load 起步,sustained pulling power for steep inclines, and balanced fuel efficiency for extended daily use. For engine parts designed for mixed-use, a well-calibrated larger bore minimizes friction while enhancing power delivery, reducing wear during both high-torque work sessions and low-stress commutes—critical for users who depend on their vehicles for both livelihood and mobility.

 COMP DIST: 20.7 – Balanced Compression for Power & Durability

The compression distance (COMP DIST) of 20.7mm is a defining specification that strikes the perfect balance between torque and engine longevity. This dimension positions the piston ideally at top dead center (TDC), creating a optimized compression ratio for thorough fuel combustion that delivers maximum power without excessive stress on engine components. A precise compression distance prevents gas leakage, ensures consistent power delivery across all RPM ranges (from idle to mid-high speed), and lowers harmful emissions—aligning with modern environmental standards for motorcycle parts and tricycle parts. For vehicles used in both work and daily travel, this feature makes the YX100-2 piston a compliant and high-performance all-in-one solution.

Piston Structural Dimensions

TOTAL HIGH: 45.4 – High-Rigidity Build for Load-Bearing Stability

Boasting a total height (TOTAL HIGH) of 45.4mm, the YX100-2 piston features a high-rigidity structure that enhances load-bearing capability without compromising agility. This dimension ensures superior alignment with the cylinder head and valve train, eliminating interference risks while maintaining optimal combustion chamber geometry under heavy torque loads (up to 550kg for tricycles). The extended height reinforces the piston’s structural integrity, allowing it to withstand compression pressures over 112 bar—making it ideal for tricycles that carry moderate-to-heavy cargo and motorcycles that navigate rough terrains without sacrificing ride comfort.

 PIN DIA: 13 & PIN LENGTH: 40 – Secure Torque Transmission

The piston pin diameter (PIN DIA) of 13mm and pin length (PIN LENGTH) of 40mm form a durable, high-strength connection between the piston and connecting rod. This combination distributes torque evenly across the rod, reducing vibration and minimizing wear during both high-torque work operation and smooth daily commutes. The high-tensile-strength, heat-treated piston pin is engineered to resist bending and shear forces, even under sudden acceleration and heavy loads—an essential attribute for long-term reliability in engine parts subjected to variable stress. This design guarantees smooth, efficient power transmission across all use cases without compromising durability.

Piston Ring Specifications: 0.8*0.8*2.0 – Low-Friction & Long-Lasting Sealing

Equipped with a premium Piston ring set of 0.8*0.8*2.0mm, the YX100-2 piston delivers the perfect balance of low friction and long-lasting sealing. The thin yet durable 0.8mm compression rings create an airtight seal in the combustion chamber, maximizing compression pressure while reducing drag—critical for both torque output and fuel efficiency. The 2.0mm oil control ring (thicker than standard 1.5mm rings) features a precision scraping design with enhanced lubricant retention, regulating oil distribution to minimize consumption and prevent carbon buildup—even during prolonged high-torque operation. This balanced ring design complements the piston’s multi-purpose functionality, ensuring efficient operation in both work and everyday scenarios—making it a superior choice among motorcycle parts and tricycle parts for versatility.

Superior Quality & Manufacturing for Mixed-Use Durability

 High-Grade Materials for Torque & Longevity

The YX100-2 piston is crafted from heat-treated, high-strength cast aluminum alloy with enhanced silicon content—selected for its exceptional torque-bearing capacity, thermal stability, and wear resistance. This material undergoes rigorous tensile testing and stress relieving to withstand the extreme temperatures (up to 355°C) and cyclic stresses of mixed-use engine operation. Unlike low-grade engine parts, the YX100-2 piston resists deformation, thermal fatigue, and premature wear, even under continuous switching between heavy loads and light commutes, extending the lifespan of both the piston and the entire engine assembly.

Precision CNC Machining for Consistency

Every YX100-2 piston is manufactured using advanced CNC machining technology, ensuring ultra-tight tolerances (±0.004mm) and consistent dimensions across all units. The precision engineering guarantees that each piston meets or exceeds OEM mixed-use standards, eliminating fitment issues and ensuring seamless integration with other motorcycle parts and tricycle parts. From the 53mm oversized cylinder diameter to the 20.7mm compression distance, every specification is calibrated for balanced torque, efficiency, and reliability, reducing installation time and minimizing downtime for repairs.
