The piston pin (wrist pin) is the vital link between the piston and connecting rod, and the Piston:ZS250 features a pin with a diameter (PIN DIA) of 16mm and length (PIN LENGTH) of 53.5mm—built to handle the intense forces of 250cc heavy-duty combustion cycles. The 16mm diameter (larger than standard pins) provides exceptional structural rigidity to withstand high compression pressure and torque, while the 53.5mm length ensures a secure, evenly distributed fit with ZS250 connecting rods. This reinforced design guarantees smooth, efficient power transfer to the crankshaft, avoiding slippage or breakage even during aggressive acceleration or maximum-load hauling. For engine parts that need to endure the rigors of 250cc heavy-duty use, this piston pin is a mark of unmatched reliability for ZS250 systems.
Professional-grade motorcycles: Perfect for off-road racing, long-distance adventure rides, and heavy-duty commuting, where power, agility, and durability are top priorities.
Industrial ZS250 tricycles: Designed to haul loads up to 2,200kg (common in construction material transport, agricultural logistics, urban delivery fleets, and waste management), ensuring the engine maintains steady power.
Utility ZS250 engines: Used in off-road work tricycles or small industrial vehicles, where durability in harsh environments (muddy construction sites, rocky rural roads, and uneven terrain) is essential.
Commercial fleet vehicles: Ideal for businesses relying on ZS250-powered tricycles for daily deliveries or transport, offering consistent performance and reduced downtime.
No matter the application, the Piston:ZS250 integrates seamlessly with ZS250 engines, making it a one-stop solution for all your 250cc heavy-duty engine parts needs.
Precision ZS250 compatibility: Every spec (from 67mm cylinder diameter to 27mm compression distance) is tailored to ZS250 engines, ensuring a perfect fit and avoiding installation errors that damage 250cc heavy-duty systems.
Heavy-duty focused durability: Forged 2024-T351 aluminum and tungsten-carbide piston rings mean the piston lasts 3x longer than generic 250cc engine parts.
Performance under extreme load: The piston optimizes fuel combustion and reduces friction, improving ZS250 engine torque by 18% at 3,000–6,000 RPM (the critical range for heavy hauling) and fuel efficiency by up to 15%—even when carrying maximum loads.
For mechanics, fleet operators, and vehicle owners, this means less downtime, lower repair costs, and a ZS250 engine that performs reliably under pressure—making the Piston:ZS250 the smart choice for motorcycle parts and tricycle parts.
