CB150-3 Piston: Industrial-Grade Heavy-Duty Engine Part for Motorcycle & Tricycle

 Introduction: The Unbreakable Power Core of Engine Parts

The Piston is the backbone of any heavy-duty combustion engine, translating fuel energy into unyielding mechanical power that withstands extreme loads, prolonged operation, and harsh environmental conditions. For those seeking industrial-grade, high-torque engine parts that redefine reliability and performance for heavy-duty applications, the CB150-3 piston stands as an industry-leading choice. Meticulously engineered to meet the most demanding needs of two-wheel and three-wheel vehicles, this piston seamlessly integrates with motorcycle parts and tricycle parts systems, catering to professional mechanics, commercial fleet operators, construction teams, agricultural users, and industrial equipment managers who prioritize brute strength, long service life, and zero-compromise reliability. Whether you’re maintaining a 2-ton cargo tricycle, repairing a construction-site utility motorcycle, or upgrading an engine for 24/7 industrial use, the CB150-3 piston delivers uncompromising performance—solidifying its status as a must-have component in the global engine parts market.

Product Overview: CB150-3 Piston – Engineered for Extreme Loads & Stability

Model Identification: CB150-3 Piston

The CB150-3 piston is a specialized industrial-grade heavy-duty model crafted with OEM-level precision, bearing the distinct CB150-3 designation that signifies its adherence to strict industrial performance and durability standards. Building on the legacy of its predecessor, this piston features a game-changing extended piston pin design and reinforced structural elements to fit CB150-3 engine platforms and compatible heavy-duty variants. Its model-specific engineering guarantees perfect integration with existing motorcycle parts and tricycle parts without modifications, saving installation time and reducing fitment risks—an essential advantage for busy workshops and commercial operators focused on minimizing downtime and maximizing productivity.

Application Scope: Beyond Motorcycle Parts

While the CB150-3 piston excels as a premium motorcycle parts component for heavy-use utility motorcycles, its versatility extends to the tricycle parts sector and industrial small-engine applications. It is specifically optimized for CB150-3-powered heavy-cargo tricycles, construction-site transport vehicles, agricultural machinery, mining utility bikes, long-haul delivery fleets, and industrial equipment operating in extreme conditions—from muddy farmlands and rocky construction sites to steep mountain roads, dust-filled mining trails, and remote industrial zones. This broad applicability makes it an invaluable asset for inventory managers and fleet owners, as it streamlines parts sourcing for vehicles that endure constant overload, rough handling, and harsh environments. Whether powering a passenger-cargo hybrid motorcycle or an industrial-grade tricycle, the CB150-3 piston maintains exceptional performance under unrelenting use.

Key Specifications: Precision Dimensions for Industrial-Grade Performance

 Cylinder-Centric Dimensions

CYL DIA: 62 – Ultra-Oversized Bore for Maximum Torque

With a cylinder diameter (CYL DIA) of 62mm—significantly larger than standard 52-57mm pistons—the CB150-3 piston is engineered to maximize combustion volume and torque density. This precise ultra-oversized bore ensures optimal compression of the fuel-air mixture, translating to brute low-end torque for heavy-load 起步,sustained pulling power for steep inclines (up to 38°), and balanced fuel efficiency for prolonged industrial use. For engine parts designed for industrial applications, a well-calibrated larger bore minimizes friction while enhancing structural stability, reducing wear during continuous high-torque operation and extending the engine’s service life by up to 55% compared to standard pistons—critical for commercial users who depend on their vehicles for uninterrupted productivity.

 COMP DIST: 26 – Ultra-Long Compression for Overload Power

The compression distance (COMP DIST) of 26mm—one of the longest in its class—is a defining specification that optimizes power for extreme overloads. This ultra-long dimension positions the piston ideally at top dead center (TDC), creating a high compression ratio for thorough fuel combustion that delivers maximum torque under full cargo loads (up to 2 tons). A precise long compression distance prevents gas leakage, ensures consistent power delivery across low-to-mid RPM ranges (ideal for heavy hauling and slow-speed maneuvering), and lowers harmful emissions—aligning with modern environmental standards for motorcycle parts and tricycle parts. For vehicles that carry industrial-grade cargo or operate in challenging terrain, this feature makes the CB150-3 piston an indispensable workhorse.

 Piston Structural Dimensions

 TOTAL HIGH: 52 – Ultra-Rigid Build for Overload Resistance

Boasting a total height (TOTAL HIGH) of 52mm—an industry-leading figure for its class—the CB150-3 piston features an ultra-rigid structure that redefines overload resistance. This dimension ensures superior alignment with the cylinder head and valve train, eliminating interference risks while maintaining optimal combustion chamber geometry even under compression pressures exceeding 135 bar. The extended height reinforces the piston’s crown and skirt with extra high-strength material, allowing it to withstand the mechanical stress of constant overloads, sudden impacts (e.g., rough terrain jolts), and repeated heavy-load cycles—making it ideal for tricycles that carry industrial cargo and motorcycles that navigate unforgiving landscapes.

 PIN DIA: 15 & PIN LENGTH: 50.5 – Extended Heavy-Duty Power Transmission

The piston pin diameter (PIN DIA) of 15mm—  for industrial strength—and pin length (PIN LENGTH) of 50.5mm (a standout extended design) form an unparalleled robust connection between the piston and connecting rod. This combination distributes extreme torque evenly across a wider surface area, drastically reducing vibration, minimizing wear, and enhancing stability during overload operation. The high-tensile-strength, heat-treated piston pin (with a tensile strength of 850+ MPa) is engineered to resist bending, shear forces, and fatigue, even under full cargo loads, rapid acceleration, and prolonged high-stress use—an essential attribute for long-term reliability in engine parts subjected to industrial-grade stress. This extended pin design ensures superior load distribution and structural integrity, setting the CB150-3 apart from standard heavy-duty pistons.

 Piston Ring Specifications: 1.2*1.2*2.5 – Industrial-Grade Sealing Excellence

Equipped with a premium industrial-grade Piston ring set of 1.2*1.2*2.5mm—thicker than standard rings—the CB150-3 piston delivers uncompromising sealing and lubrication performance. The two 1.2mm compression rings (chrome-plated with nitride coating for exceptional wear resistance) create an airtight seal in the combustion chamber, maximizing compression pressure and preventing gas leakage that can degrade performance under overloads. The 2.5mm oil control ring features a reinforced triple-scraping design with multiple contact points, regulating lubricant distribution to reduce consumption and prevent carbon buildup—even during 24/7 industrial operation and extended periods of high-torque use. This heavy-duty ring design complements the piston’s industrial functionality, ensuring efficient operation in the most demanding scenarios—making it a superior choice among motorcycle parts and tricycle parts for longevity.
