2022 Yamaha Aerox 155 Overview

For 2022, Yamaha offers the Aerox 155 as a scooter motorcycle with 155 cc on tap. The 2022 Yamaha Aerox 155 is built around a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 10.5:1. Internally, bore and stroke are 58 x 58.7 mm. Out on the road, the Aerox 155 delivers 13.9 Nm @ 6500 Revolutions of torque. In everyday use, the 2022 Aerox 155 tips the scales at 126 kg, carries a 5.50-litre fuel tank, offers a seat height of 790 mm and spans a 1350 mm wheelbase. That's roughly 59.9 kg lighter than the average scooter motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2022 Yamaha Aerox 155 spec sheet below.

2022 Aerox 155 - Pros & Cons

Strengths

Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
Low-maintenance final drive: Belt (final drive) final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

Modest fuel capacity: A 5.50-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling on the Aerox 155 comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Valve clearance checks

Valve clearances on Single Overhead Cams (SOHC)-equipped engines like the Aerox 155's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.

Brake disc and pad wear

Single disc. ABS up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by Telescopic fork, 26mm up front and Unit Swing at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Belt final drive keeps day-to-day maintenance minimal on the Aerox 155 - just periodic tension and wear checks rather than the regular cleaning a chain demands.

Frame & chassis check

The Underbone, steel chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

Low-speed handling

The Aerox 155's 126 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.

Aerox 155 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2022 Yamaha Aerox 155 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept Aerox 155 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a Aerox 155's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the Aerox 155's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.

Valve clearance service

There's no reliable seat-of-the-pants way to tell if a Aerox 155's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
