Welcome to R World
Yamaha has a rich heritage of building the most sought after Supersport
motorcycles designed to deliver the pinnacle of performance on and off the
track. From the rider-friendly YZF-R3 to the competition-focused YZF-R1M, the
Yamaha R-series model lineup provides options for riders of all skill levels to
experience the pure exhilaration of R World.
2020 YZF-R3 – R World is Calling
The YZF-R3 (R3) is the ultimate entry-level Supersport bike with Yamaha’s
iconic aggressive design and outstanding performance, making it the perfect
choice for first-time riders or experienced sportbike pilots who prefer a
lightweight, nimble machine.
Powered by a reliable 321cc engine, the R3 delivers excellent performance for
navigating cross-town traffic, carving twisty roads, or participating in a track
day. Featuring the latest combustion technology, lightweight forged aluminum
pistons, and all-aluminum DiASil cylinders with an offset design, the
smooth-running and quick-revving R3 engine produces easy-to-manage power.
A lightweight steel frame cradles the engine’s crankcase within the chassis,
resulting in approximately 50/50 front-rear weight distribution for the perfect
balance of rigidity and weight. An asymmetric swingarm efficiently delivers
engine power to the rear wheel, while a preload-adjustable KYB rear shock
mounted in a Monocross suspension design contributes to a mass centralization of
weight. To help achieve the right balance of comfort and sport riding
performance for both street and track, the R3 features a KYB 37mm inverted front
fork to provide the rider with outstanding handling during cornering and
braking. ABS is also available, adding to confidence-boosting stopping
performance.
The 2020 YZF-R3 will be available in Team Yamaha Blue. Models equipped with
ABS will be available in Team Yamaha Blue, Matte Black, and Matte Silver.
Engine
Lightweight, compact, 321 cc, liquid-cooled, DOHC, 8-valve
(4-valves/cyl), fuel injected, inline-twin cylinder engine. The engine has
been designed to provide solid performance right across the rev range, with
very linear throttle response, low vibration & excellent fuel economy.
Downdraft style, compact combustion chamber
4 valves per cylinder to enhance low-to mid-range torque
straight intake path into the combustion chamber for excellent power
output
The YZF-R3 uses regular 87 octane gas.
Valves are 26 mm (intake) and 22.5 mm (exhaust) in diameter.
Isonite surface treatment on the valve stems for improved durability
& wear resistance
valves feature carbon cutters on the valve stems to help reduce
carbon build-up during slower speed operation
Valve adjustment interval is every 42,000 km.
Automatic cam chain tensioner.
reduces mechanical engine noise & maintenance
Lightweight, all aluminum DiASil cylinder (die cast all aluminum
cylinder with silicone content).
offers outstanding cooling performance / heat dissipation for
consistent power delivery
reduces weight since there are no heavy liners & cylinder is made
completely of aluminum
Offset cylinder design.
cylinder is offset 7 mm relative to the crankshaft (to the exhaust
side)
reduces frictional losses between the pistons & cylinder wall during
the power stroke
improved power output & improved fuel economy
180-degree crankshaft with uneven firing order.
helps reduce “pumping losses” for maximum power output
features optimized rigidity balance for light, agile handling with
excellent stability
engine is a stressed member of the chassis, allowing a lighter, more
compact main frame design
frame features a mix of both solid & rubber engine mounts
Electrostatic paint helps prevent corrosion
The riding position is one of the most important features of the
R3. Despite its supersport styling, the R3 offers excellent rider comfort
thanks to its upright riding position.
Key chassis geometry figures include:
1380 mm (54.3″) wheelbase
25 degrees of rake & 95 mm of trail
50 / 50 front to rear weight distribution
chassis dimensions and shape have been designed to centralize mass &
lower the centre of gravity to provide the rider with light, agile
handling
Tapered, long design, high tensile steel swingarm.
lightweight design reduces unsprung weight for superior suspension
performance
excellent rear wheel traction & control
37 mm KYB upside-down (inverted) fork offers 130 mm (5.1″) of
wheel travel.
plastic chip guards help prevent damage to the fork tubes & seals
Adjustable Monocross link-less rear suspension with 125 mm
(4.9″) of wheel travel.
features a single KYB rear shock with 7 levels of preload
adjustability
adjustable design allows rider to tailor preload settings to match
load & road condition
ABS-equipped 298 mm floating front disc brake squeezed by a
twin-piston caliper.
provides solid stopping power
brake force & feel are tailored towards new riders
ABS-equipped 220 mm floating rear disc is squeezed by a
lightweight, single-piston, slide-type caliper.
Anti-lock braking system (ABS).
controlling ECU & hydraulic unit are combined into a single compact
unit to reduce weight & centralize mass
when ABS system senses impending wheel lock-up (via active type
wheel sensors) it regulates hydraulic braking pressure to the point just
before the wheel or wheels lock-up
ABS provides excellent control under hard braking or when braking on
wet, slippery or loose surfaces
Lightweight, cast-aluminum 10-spoke mag wheels.
front wheel size is MT2.75-17 fitted with a 110/70-17 tire
rear wheel is MT4.00 fitted with a 140/70-17 tire
Lightweight hollow axles front & rear.
Clip-on style handlebars.
provide a supersport image but offer a comfortable, more upright
riding position since they are mounted above the top triple clamp
Handlebar position is 22 mm lower than previous model
14-litre fuel tank with styling adopted from R1 and R6 models.
offers a slim design with great knee grip
“reserve” portion of the tank is 3 litres (low fuel light will
illuminate)
tank is steel with plastic covers, which can reduce costs in the
event of damage
Separate rider & passenger seats with low 780 mm (30.7″) seat
height.
offer excellent comfort
narrow-design rider seat makes it easier to touch feet flat on the
ground
passenger seat can be removed & replaced by the optional Genuine
Yamaha Accessory rear seat cowl if desired
