2018 Yamaha MT-09 Overview

Yamaha MT-09 is a naked bike motorcycle, displacing 847 cc. Power comes from a Four stroke, transverse triple cylinder, DOHC, 4 valve per cylinder engine, a compression ratio of 11.5:1. On the performance side, it delivers 84.6 kW @ 10,000 rpm of peak power and 87.5 Nm @ 8,500 rpm of torque. Top speed is factory-quoted at 209.8 km/h. On the road, the 2018 MT-09 tips the scales at 188 kg, carries a 14-litre fuel tank, offers a seat height of 815 mm and spans a 1440 mm wheelbase. That's roughly 20.5 kg lighter than the average naked bike motorcycle in our database. The full 2018 Yamaha MT-09 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2018 MT-09 - Pros & Cons

Strengths

Strong power output: With 84.6 kW @ 10,000 rpm and 87.5 Nm @ 8,500 rpm of torque on tap, the MT-09 is no slouch for its class.
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.

Considerations

Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Cooling system servicing

MT-09's Liquid cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.

Fuelling & injector care

The fuel injection on the MT-09 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Brake disc and pad wear

Braking up front comes from 2x 298mm discs - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The MT-09's suspension runs Telescopic fork at the front. The rear uses Swingarm. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The MT-09 uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Frame & chassis check

Built around a Diamond frame, the MT-09's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

MT-09 - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2018 Yamaha MT-09, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy MT-09 should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a MT-09's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the MT-09 needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
