Enhance Engine Performance with Piston:TH90/JH90 – Top-Grade Engine Parts for Motorcycles & Tricycles

Introduction: Piston:TH90/JH90 – The Core of Reliable Engine Operation

In the world of engine parts, the piston acts as the "power converter" that transforms fuel combustion into mechanical energy—making it a critical component for any motorcycle or tricycle engine. The Piston:TH90/JH90 stands out as a premium solution in the realm of motorcycle parts and tricycle parts, engineered exclusively to meet the precise specifications of TH90 and JH90 engine models. Whether you’re repairing a daily-commute motorcycle, maintaining a commercial tricycle, or restoring a vintage engine, this piston delivers consistent power, minimizes wear, and ensures long-term engine stability. For anyone seeking durability and performance in engine parts, the TH90/JH90 piston is the ultimate choice to keep engines running at their peak.

Key Specifications of Piston:TH90/JH90 – Precision Engineered for Perfect Fit

Every dimension of the Piston:TH90/JH90 is calibrated to match the unique needs of TH90 and JH90 engines, eliminating fitment issues and guaranteeing optimal functionality. Below are the critical specs that set this piston apart from generic engine parts:

Model: TH90/JH90 – A Mark of Guaranteed Compatibility

The TH90/JH90 model designation is more than just a label—it’s a promise of seamless integration. This piston is specifically designed to fit TH90 and JH90 engine series, which are widely used in mid-displacement motorcycles and utility tricycles. For mechanics and vehicle owners, this means zero guesswork during installation: the piston aligns flawlessly with cylinder walls, connecting rods, and other engine components, avoiding the costly mistakes that come with mismatched motorcycle parts or tricycle parts. As a trusted name in engine parts, the TH90/JH90 piston streamlines repairs and ensures your engine operates as intended.

CYL DIA: 47 – Optimizing Combustion for Balanced Power

With a cylinder diameter (CYL DIA) of 47mm, the Piston:TH90/JH90 is engineered to maximize combustion efficiency in mid-displacement engines. This precise diameter creates an ideal volume for air-fuel mixture compression, striking a balance between robust power output and fuel economy. For motorcycles used for long-distance rides or tricycles hauling moderate loads, the 47mm size ensures smooth acceleration without excessive fuel consumption—making it a superior choice among engine parts focused on versatility and performance.

TOTAL HIGH: 42.6 – Stability That Reduces Engine Vibration

The total height (TOTAL HIGH) of 42.6mm is a critical factor in the piston’s ability to maintain stability during high-speed operation. This dimension ensures the piston fits snugly within the engine block, maintaining consistent clearance with the cylinder head and crankshaft. A stable piston minimizes vibration, reduces friction between moving parts, and prevents premature wear—essential benefits for motorcycle parts and tricycle parts that endure daily use or heavy loads. The 42.6mm height also avoids interference with valve trains or other engine components, extending the overall lifespan of your engine.

COMP DIST: 20.2 – Fine-Tuning Compression for Torque & Efficiency

Compression distance (COMP DIST) of 20.2mm plays a pivotal role in defining the engine’s compression ratio—and the Piston:TH90/JH90 is calibrated to perfection. A 20.2mm compression distance optimizes the engine’s compression ratio, enhancing fuel combustion, reducing harmful emissions, and boosting low-end torque. This is particularly valuable for tricycles used in urban delivery or motorcycles navigating hilly terrain, where quick torque response is key. As a result, this piston stands out among engine parts that prioritize both performance and environmental compliance.

RING: 1.01.02.0 – Durable Piston Ring for Superior Sealing

No piston is complete without a reliable piston ring, and the Piston:TH90/JH90 comes equipped with a 1.0mm1.0mm2.0mm piston ring set. This piston ring is crafted from heat-resistant alloy steel, designed to create an airtight seal between the piston and cylinder wall. It prevents oil leakage into the combustion chamber (avoiding smoke and reduced efficiency) and ensures maximum compression for consistent power. Unlike flimsy piston rings in generic motorcycle parts or tricycle parts, this ring withstands extreme temperatures (up to 250°C) and constant motion, delivering long-lasting performance and minimizing the need for frequent replacements.

PIN DIA: 13 & PIN LENGTH: 38 – Robust Power Transfer for Reliable Operation

The piston pin (wrist pin) is the vital link between the piston and connecting rod, and the Piston:TH90/JH90 features a pin with a diameter (PIN DIA) of 13mm and length (PIN LENGTH) of 38mm. This robust design ensures the pin can handle the high forces generated during combustion, without bending or breaking under stress. The 13mm diameter provides exceptional strength, while the 38mm length ensures a secure fit with the connecting rod—guaranteeing smooth power transfer to the crankshaft. For engine parts that need to endure heavy use (like tricycle parts for small-scale logistics), this piston pin design is a mark of unmatched reliability.

Versatile Applications – Ideal for Motorcycles & Tricycles Alike

One of the greatest strengths of the Piston:TH90/JH90 is its versatility. As a core component in both motorcycle parts and tricycle parts, it fits a wide range of vehicles powered by TH90 or JH90 engines, including:

Touring motorcycles: Perfect for long-distance travel, where reliability and fuel efficiency are top priorities.
Light cargo tricycles: Designed to handle loads up to 700kg, ensuring the engine maintains power during hauling.
Utility tricycles: Used in farming, small-scale delivery, or rural transportation, where durability in rough terrain is essential.
No matter the application, the TH90/JH90 piston integrates seamlessly with compatible engines, making it a one-stop solution for all your engine parts needs.

Why Choose Piston:TH90/JH90 Over Other Motorcycle Parts & Tricycle Parts

When selecting a piston for your TH90 or JH90 engine, the TH90/JH90 piston stands out for three key reasons:

Precision compatibility: Every spec is tailored to TH90/JH90 engines, ensuring a perfect fit and avoiding installation errors that damage engines.
Durability: Forged aluminum and hard anodizing mean the piston lasts 3x longer than generic engine parts.
Performance boost: From the 47mm cylinder diameter to the 20.2mm compression distance, every feature is designed to increase torque, improve fuel efficiency, and reduce emissions.

For mechanics and vehicle owners, this means less downtime, lower repair costs, and a more reliable engine—making the TH90/JH90 piston the smart choice for motorcycle parts and tricycle parts.
