Motorcycle Cylinder Set for Yamaha NMAX155

The Motorcycle Cylinder Set for Yamaha NMAX155 by Max Trading is a high-performance single-cylinder, water-cooled cylinder assembly designed for Yamaha NMAX155 engines. As a professional China motorcycle engine parts manufacturer and supplier, we focus on durability, thermal efficiency, and long-term engine stability.

Parameter Configuration

Detailed Product Description

Advanced Aluminum-Silicon Alloy Cylinder Block

The Motorcycle Cylinder Set for Yamaha NMAX155 features a single-cylinder, water-cooled aluminum-silicon alloy cylinder block with approximately 20% silicon content. This material structure provides excellent wear resistance and thermal stability.

Unlike traditional cast-iron or lined cylinders, this design:

Eliminates the need for cylinder liners or surface coatings

Significantly reduces overall engine weight

Improves heat transfer efficiency

Extends service life under high-load operation

According to durability testing, cylinder wall wear remains below 0.10 mm after 200,000 km, ensuring long-term reliability for daily commuting and commercial use.

High-Efficiency Water-Cooling System

Compared with air-cooled structures, the compact water-cooled system used in this Motorcycle Cylinder Set for Yamaha NMAX155 allows more precise control of operating temperature.

Key advantages include:

Faster heat dissipation with ultra-thin radiator design

Stable cylinder temperature under varying riding conditions

Reduced risk of thermal deformation and power loss

Improved engine reliability during long-distance or high-speed riding

This cooling structure supports consistent engine performance in both urban and highway environments.

Offset Cylinder Design for Reduced Friction

The cylinder adopts an offset design, positioning the cylinder centerline slightly toward the exhaust side. During combustion, the combined force of piston downforce and connecting rod reaction shifts downward instead of laterally.

This structure:

Reduces side thrust on the cylinder wall

Minimizes friction losses

Improves mechanical efficiency

Enhances long-term cylinder surface integrity

As a result, engine smoothness and durability are noticeably improved.

Optimized Fuel Injection & VVA Valve System

The 12-hole fuel injector significantly improves fuel atomization, contributing to:

• More complete combustion
• Better throttle response
• Improved fuel economy
• Stable power delivery

In addition, the VVA (Variable Valve Actuation) system plays a key role in optimizing engine performance across the full RPM range:

At low speeds, only two valves open to reduce pumping losses and improve torque

At 7350 rpm, the high-lift camshaft automatically engages, opening all four valves

Achieves strong low-speed torque and high-speed power output
