2022 NMAX 155 - Pros & Cons
Strengths
-
🔧
Fuel injection: The fuel injection injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
Considerations
-
ℹ️
Age-related wear: As with any used NMAX 155, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.
Owner Experiences & Common Issues
Throttle response and fuelling
The fuel injection on the 2022 Yamaha NMAX 155 is generally well-regarded. Some owners note a slight hesitation at small throttle openings when cold, which clears once the engine reaches operating temperature. A quick visual check of the injector connectors during routine servicing is good practice on higher-mileage examples.
Valve clearance checks
Single Overhead Cams (SOHC) engines should have valve clearances checked at the manufacturer's specified interval. Owners report that clearances can tighten over time on higher-mileage bikes, leading to slight ticking from the top end. Catching it early keeps the job simple and avoids more costly remediation.
NMAX 155 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2022 Yamaha NMAX 155, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained NMAX 155 should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any NMAX 155. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. The sump holds 1 litres, so budget for that volume of quality motorcycle-specific engine oil. Always use the correct viscosity grade as specified in the owner's manual.
Fuel system care
The NMAX 155's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
Valve clearance service
Check that valve clearances have been adjusted at the correct intervals on any used NMAX 155. This is a job many owners skip because the bike does not immediately feel wrong - but tight clearances accelerate valve seat wear. Ask for proof it has been done.
