2021 Yamaha YZF-R3: The R1’s Younger Sibling
The Yamaha YZF-R3 is a modern entry-level sport, Japanese-made motorcycle, being introduced only in 2015. With power coming in at approximately 50 HP from the 320cc inline twin lightweight aluminum engine, the R3 is more than capable of hard acceleration, cruising at speed, and track riding. Compared to the previous year, this year’s model has come up 7 lbs to be 375 lbs wet.
Yamaha Motorcycles has also continued the YZF-R3 Monster Energy MotoGP model, which is primarily cosmetic with new panels that reflect the YZR-M1’s aggressive racing lines with Monster sponsorship. No engine or systems modifications are made, and it uses the same dual zone ABS, anti-slip, and traction control systems that the base YZF-R3 uses. Another difference from the previous year is that for 2021, the Monster Energy MotoGP model is no longer sold in Canada.
The YZF-R3 starts at $4,999 USD / $6,299 CAD and the YZF-R3 Monster Energy MotoGP starts at $5,599 USD.

2021 Yamaha YZF-R3 & Monster Energy MotoGP YZF-R3 Features
Sleek R-Series Styling
Featuring flowing bodywork and ergonomics inspired by the MotoGP® YZR-M1®, complemented by new colors and graphics, the YZF-R3® is sleek, aerodynamic and refined.
High-Revving Supersport Engine
Yamaha’s championship-winning technology gives the YZF-R3 a broad spread of power with exciting high-rpm performance.
The R3’s inverted fork works with a Monocross® rear shock to provide exceptional handling, with balanced chassis rigidity, a near 50/50 weight balance, and damping and spring settings designed for a wide range of road conditions.
With a fully-fueled weight starting at only 375 pounds and a seat height of only 30.7 inches, the YZF-R3 is ultra-light, nimble, and confidence-inspiring on everything from tight city streets to wide-open racetracks.
A range of exclusive technologies ensures the YZF-R3 combines Yamaha’s legendary refinement and reliability with thrilling performance, all while sipping fuel at an efficient 56 mpg.
Potent Twin-Cylinder Powerplant
Yamaha’s 321cc liquid-cooled, inline 2-cylinder engine delivers excellent power and performance throughout the rpm range. With a 180-degree crank design and integrated counterbalancer, the layout minimizes vibrations for a smooth, refined engine character.
High-Revving Engine Architecture
With a compression ratio of 11.2:1, double overhead cams (DOHC) and four-valve cylinder heads, the YZF-R3 motor is designed for quick- revving performance and high-rpm efficiency to deliver an exciting ride with a broad spread of power.
A smooth-shifting six-speed gearbox ensures the rider always has the right ratio, whether riding through tight canyon corners or racetrack straightaways.
Modern Fuel Injection
Downdraft induction fuel injection system provides easy starting, excellent fuel economy and responsive performance in all conditions.
Advanced Cylinder Construction
Yamaha’s unique DiASil—a high-silicon aluminum alloy—engine block is used to ensure excellent heat dissipation, with an innovative offset cylinder design that reduces horsepower loss and improves both power and fuel efficiency.
Strong and Lightweight Pistons
Forged aluminum pistons—the same technology used for the YZF- R1® —means lighter weight and excellent strength at higher temperatures, ensuring reliability at higher rpm.
Compact Exhaust System
The short muffler design features modern styling and helps to centralize mass, improving agility for ultra-responsive handling.
Inverted Front Fork
The YZF-R3 features an inverted fork with optimized spring and damping settings, significantly improving fork rigidity, front-end feedback and control feel. The design also includes a YZR-M1-inspired top clamp for improved supersport style.
Monocross Rear Shock
The single-shock design further centralizes mass and is tuned to strike a balance between ride comfort and sporty performance, for capability across a wide range of uses, from urban commuting to track days. It’s also adjustable for spring preload which accounts for passengers or cargo.
Potent Braking with ABS
The 298mm floating-mount front disc brake ensures excellent stopping power, supported by a 220mm rear disc, and an antilock braking system boosts rider confidence and prevents wheel lock-ups in reduced-traction conditions.
Sportbike-Spec Wheels and Tires
Stylish 10-spoke cast aluminum wheels minimize unsprung weight for improved suspension responsiveness and refined handling. Grippy Dunlop® radial tires offer enhanced grip and feedback for sporty riding, too.
Thanks to the engine placement and overall machine dimensions, the YZF-R3 features a near 50/50 front/rear weight distribution for enhanced performance, especially in dynamic canyon-carving or racetrack riding environments.
Sleek R-Series Styling
The R3’s aggressive design continues the legendary styling born from the YZR-M1 MotoGP® machine and improves overall aerodynamics at high speeds, too. The glaring face of the R3 features compact LED headlights with a central air duct that maximizes cooling airflow for the engine.
Light Emitted Diode (LED) elements are used for both the taillight unit and headlights. Not only do LEDs offer long life with minimal power draw, they provide brilliant illumination for confidence and visibility day or night.
Refined Sportbike Ergonomics
Thanks to the low-profile fuel tank design and relatively compact handlebar position, the rider is able to naturally grip the machine for confidence, especially when tucking aggressively behind the windscreen on the racetrack.
The compact multi-function meter informs the rider of gear position, fuel capacity, real time and average fuel economy, water temp, clock and an oil change trip meter—all presented in a clean, modern layout.
