Product Overview

This high-quality Original Gasket Cylinder is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2025) models.

The Gasket Cylinder is a precision-formed base gasket seated between the cylinder barrel and the crankcase, maintaining an oil and gas-tight seal at the base of the cylinder. When the gasket deteriorates, warps, or is disturbed during service without being replaced, oil can seep from the base joint, combustion blow-by can escape downward into the crankcase, and engine compression drops, affecting throttle response and overall performance. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha NMAX 125 scooter.

Complete Part Guide

Compression can leak easily without a proper seal, and that's exactly the job this part does. The original Yamaha NMAX125 Cylinder Gasket (B65-E1351-10) for 2015-2025 models seals the lower cylinder area, ensuring combustion pressure stays contained while oil pathways remain separated. It's essential for efficient engine operation. Built to Yamaha's original standard, it provides accurate fitment, strong sealing integrity, and reliable performance. In stock at Part Hive's London hub, order before 1 PM for same-day UK dispatch.

If you're seeing a bit of oil around the base or noticing a drop in compression, it's usually the gasket. Over time, heat and previous work can cause it to lose its seal. We come across this a lot, especially on engines that have been apart before. Riders often leave it if it's minor, but it only gets worse. We replace it with the correct original Yamaha NMAX-125 base cylinder gasket, and it puts it right, with a tight seal, no leaks, and everything sitting properly.
