In the landscape of engine parts, the piston is the critical component that transforms fuel combustion into usable mechanical power—especially vital for 70cc engines, which are trusted worldwide for their fuel efficiency and daily usability. The Piston:JH70 stands out as a top-tier solution in the world of motorcycle parts and tricycle parts, engineered exclusively to match the exact specifications of JH70 engine models. Whether you’re repairing a JH70 commuter motorcycle, maintaining a small-scale JH70-powered tricycle, or restoring an aging 70cc engine, this piston delivers consistent power, minimizes wear, and ensures long-term reliability. For anyone seeking durable, high-performance engine parts for JH70 systems, the Piston:JH70 is the ultimate choice to keep engines running at their peak.
The total height (TOTAL HIGH) of 41.15mm is a critical factor in the piston’s ability to maintain stability during JH70 engine operation—especially important for vehicles that run for hours daily (like daily-commute motorcycles or delivery tricycles). This dimension ensures the piston fits snugly within the JH70 engine block, maintaining consistent clearance with the cylinder head and crankshaft. A stable piston minimizes vibration (reducing rider fatigue in motorcycles and component stress in tricycles), lowers friction between moving parts, and prevents premature wear—key benefits for motorcycle parts and tricycle parts that endure frequent use. The 41.15mm height also avoids interference with valve trains or piston skirts, extending the overall lifespan of your JH70 engine.
No piston is complete without a reliable piston ring, and the Piston:JH70 comes equipped with a 1.0mm1.0mm2.0mm piston ring set—engineered for the unique demands of JH70 engines. Crafted from heat-resistant alloy steel with a nickel-plated surface, this piston ring creates an airtight seal between the piston and cylinder wall, preventing oil leakage into the combustion chamber (avoiding smoke and reduced efficiency) and ensuring maximum compression. Unlike thin, low-quality rings in generic engine parts that wear out quickly, the 1.0mm/2.0mm design withstands temperatures up to 240°C and resists corrosion—making it durable enough for daily use in JH70 motorcycles and tricycles. It also requires minimal maintenance, reducing long-term repair hassle.
Urban commuter motorcycles: Perfect for short-to-long daily rides (10–80 km), where fuel efficiency and easy handling are top priorities.
Lightweight JH70 tricycles: Designed to haul loads up to 400kg (common in local delivery, small farming, or rural transportation), ensuring the engine maintains steady power.
Utility JH70 engines: Used in off-road mini-tricycles or small work vehicles, where durability in rough terrain (dirt roads, gravel paths) is essential.
No matter the application, the Piston:JH70 integrates seamlessly with JH70 engines, making it a one-stop solution for all your 70cc engine parts needs.
