Aerox Bore Cylinder KIT NMAX155-63MM Silver

The Yamaha Aerox and NMAX 155 are already leaders in their class, but for riders who crave more torque, quicker acceleration, and higher top speeds, factory displacement is just the beginning. This 63mm Big Bore Cylinder Kit increases your engine's capacity, providing a massive boost in "grunt" for city overtaking and highway cruising. Finished in a sleek Silver, this kit is engineered for riders who want professional-grade performance without compromising engine cooling.

Why the 63mm Big Bore Kit is a Performance Essential:
Massive Displacement Increase: By increasing the bore to 63mm, this kit significantly boosts your CCs, leading to a noticeable gain in horsepower and, more importantly, a surge in low-to-mid range torque.

Superior Ceramic/Alloy Cooling: The cylinder is crafted from high-grade aluminium with specialized coating to ensure rapid heat dissipation. This keeps your engine running cool even under the increased stress of high-performance riding.

High-Compression Piston Design: Included is a precision-forged 63mm piston designed to optimize the combustion cycle, giving you a sharper throttle "snap" and more efficient power delivery.

Seamless Bolt-On Fit: Engineered specifically for the Yamaha Aerox 155 and NMAX 155 (V1/V2) liquid-cooled engines. It retains all original mounting points and coolant passages for a reliable installation.

Lightweight Performance: The all-alloy construction reduces reciprocating mass compared to heavy iron sleeves, allowing your engine to rev more freely and reducing vibration at high RPMs.
