2020 Yamaha X-MAX 300 Overview

For 2020, Yamaha offers the X-MAX 300 as a scooter motorcycle with 292 cc on tap. The 2020 Yamaha X-MAX 300 is built around a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 10.9:1. Internally, bore and stroke are 70 x 75.9 mm. Out on the road, the X-MAX 300 delivers 29 Nm @ 5750 Revolutions of torque. In everyday use, the 2020 X-MAX 300 tips the scales at 179 kg, carries a 13-litre fuel tank, offers a seat height of 795 mm and spans a 1540 mm wheelbase. That's roughly 18.7 kg lighter than the average scooter motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2020 Yamaha X-MAX 300 spec sheet below.

2020 X-MAX 300 - 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

Age-related wear: No particular mechanical concern flags for the X-MAX 300 - condition on any used example comes down to how well it's been looked after.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling on the X-MAX 300 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 X-MAX 300'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. Hydraulic. 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 forks 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 X-MAX 300 - just periodic tension and wear checks rather than the regular cleaning a chain demands.

Frame & chassis check

The Underbone 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.

X-MAX 300 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2020 Yamaha X-MAX 300 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 X-MAX 300 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a X-MAX 300's engine - keep to the manufacturer's interval rather than stretching it. The sump holds 1.30 litres, so budget for that volume of quality motorcycle-specific engine oil. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the X-MAX 300'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 X-MAX 300'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.
