For owners of 110cc vehicles—from the iconic C8 motorcycle, a favorite for daily commutes and rural mobility, to hardworking utility tricycles—investing in high-quality engine parts is the key to consistent performance and reduced downtime. The C8 Piston emerges as a purpose-built solution, crafted to match the demands of 110cc engines where durability, efficiency, and perfect fit are non-negotiable. As the central component of the combustion chamber, this Piston works in seamless harmony with Piston ring sets to seal the cylinder, transfer combustion power to the crankshaft, and maintain optimal compression. Whether you’re repairing a C8 motorcycle with authentic motorcycle parts, upgrading a 110cc utility tricycle with robust tricycle parts, or maintaining small-engine machinery, the C8 Piston delivers the reliability and performance that 110cc vehicle users trust.
CYL DIA (Cylinder Diameter): 51 mm – This precision-machined diameter ensures a tight, leak-free fit within 110cc cylinder bores, critical for preserving peak compression. The 51mm size optimizes combustion pressure, delivering robust low-end torque ideal for navigating city traffic (on motorcycles) or hauling moderate cargo (on tricycles) while keeping fuel consumption economical.
TOTAL HIGH (Total Height): 39.2 mm – The balanced total height strikes a perfect compromise between structural integrity and installation flexibility. It fits seamlessly into the C8’s engine bay and most 110cc engine setups without modifications, ensuring compatibility with existing motorcycle parts or tricycle parts while withstanding the rigors of frequent use.
COMP DIST (Compression Distance): 20.2 mm – This carefully calculated distance optimizes the engine’s compression ratio, balancing power output and fuel efficiency. It ensures efficient combustion in 110cc setups, preventing pressure loss and maximizing energy harnessed from each fuel-air mixture—essential for budget-conscious daily riders and small-business tricycle operators.
Piston Ring Dimensions: 1.01.02.0 mm – The (included) Piston ring set features three specialized rings (primary compression, secondary compression, oil control) with durable 1.0mm top/bottom rings and a 2.0mm oil control ring. This design enhances sealing performance, prevents oil contamination of the combustion chamber, and improves heat transfer—critical for 110cc engines operating in stop-and-go or prolonged-use scenarios.
PIN DIA (Piston Pin Diameter): 13 mm – The 13mm piston pin ensures a secure, low-friction connection to the connecting rod. Its robust diameter handles the cyclic stresses of 110cc combustion while maintaining smooth movement, extending the piston’s service life.
PIN LENGTH: 38 mm – This length provides stable support for the connecting rod, distributing pressure evenly across the piston’s wrist pin boss. It ensures alignment and reduces lateral movement, preventing premature wear on both the piston and rod components.
High-Strength Heat-Resistant Aluminum Alloy – Constructed from grade A356 aluminum alloy (reinforced with 7% silicon), the C8 Piston withstands temperatures up to 340°C and the pressure of 110cc combustion. The material offers exceptional thermal conductivity, dissipating heat quickly to prevent overheating and warping—common issues in compact engines with limited cooling capacity.
CNC Precision Machining – Every C8 Piston undergoes rigorous CNC machining, with tolerances within 0.001mm. This ensures a perfect fit with the cylinder bore and Piston ring grooves, eliminating leaks and maintaining consistent compression. Unlike generic pistons that require tedious adjustments, this part is ready for installation out of the box.
Anti-Wear Skirt Coating – The piston’s skirt features a specialized molybdenum disulfide coating, reducing friction between the piston and cylinder wall by up to 38%. This coating minimizes wear, extends the piston’s lifespan by up to 50% compared to uncoated alternatives, and improves fuel efficiency—ideal for frequent-use vehicles like daily commuter motorcycles or delivery tricycles.
Reinforced Wrist Pin Boss – The wrist pin boss is strategically reinforced with additional material to handle the cyclic loads of 110cc engines, preventing cracking or deformation even under prolonged high-RPM operation. This structural enhancement adds an extra layer of reliability for heavy-use scenarios, such as tricycles hauling 100+ kg loads.
C8 Motorcycle Compatibility – It’s a direct replacement for all C8 variants, including base models and upgraded editions. Whether you’re repairing a well-used C8 that’s logged thousands of kilometers or restoring an older model, the C8 Piston integrates seamlessly with the bike’s original motorcycle parts to restore factory-level performance.
110cc Tricycle Compatibility – For 110cc utility tricycles used for small-scale cargo transport (e.g., urban food delivery, rural errand-running, or light construction work), the C8 Piston is a reliable upgrade. It works with standard tricycle engine setups, pairing with tricycle parts to deliver the durability needed for daily heavy use without straining the engine.
110cc Small-Engine Compatibility – Beyond two and three-wheelers, the C8 Piston fits 110cc small-engine machinery (e.g., mini generators, small agricultural pumps) that require 51mm piston dimensions, expanding its utility across engine parts applications.
Enhanced Compression & Power – The precision 51mm cylinder diameter and optimized 20.2mm compression distance ensure maximum compression, delivering a noticeable boost in low-end torque (up to 6.0 N·m). This makes C8 motorcycles more responsive in traffic and tricycles better equipped to handle steep hills or moderate cargo.
Improved Fuel Efficiency – By maintaining a tight seal with the Piston ring set and minimizing combustion leaks, the C8 Piston reduces fuel waste by up to 13% compared to worn or ill-fitting pistons. For daily commuters logging 110km weekly, this translates to monthly fuel savings of $16–$23— a significant benefit for budget-conscious users.
Smoother, Quieter Operation – The reduced friction and balanced design minimize engine vibration and noise, creating a more comfortable ride. This is particularly noticeable in stop-and-go city traffic, where rough idling or jerky acceleration is a common annoyance with low-quality engine parts.
Reduced Maintenance Downtime – The high-strength materials and anti-wear features reduce wear on the piston, cylinder walls, and connecting rod, extending the engine’s overall lifespan. Many users report their engines running reliably for an additional 35,000km after installing the C8 Piston—saving time and money on repairs.
