On the performance side, it delivers 30.9 kW 41.4 hp @ 10750 rpm of peak power and 29.6 Nm @ 9000 rpm of torque. On the road, the 2018 YZF-R 3 tips the scales at 169 kg, carries a 14-litre fuel tank, offers a seat height of 779.7 mm and spans a 1379.2 mm wheelbase. That's roughly 33.7 kg lighter than the average sport motorcycle in our database. The full 2018 Yamaha YZF-R 3 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2018 YZF-R 3 - Pros & Cons

Strengths

Strong power output: With 30.9 kW 41.4 hp @ 10750 rpm and 29.6 Nm @ 9000 rpm of torque on tap, the YZF-R 3 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

YZF-R 3'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 YZF-R 3 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 Single 298mm disc 2 piston caliper - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The YZF-R 3's suspension runs 41mm KYBø telescopic fork at the front. The rear uses Adjustable KYB® single shock. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The YZF-R 3 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 Delta box, the YZF-R 3's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

YZF-R 3 - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2018 Yamaha YZF-R 3, 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 YZF-R 3 should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a YZF-R 3'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 YZF-R 3 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.
