NEW ASSIST & SLIPPER CLUTCH

A first for the YZF-R3, the new Assist & Slipper (A&S) clutch utilizes an assist cam and slipper cam to help inhibit excessive engine braking for a smooth, easy-to-handle feeling during downshifts while also reducing the amount of force required to pull the clutch lever for less hand fatigue.

SMARTPHONE CONNECTIVITY

The 2025 YZF-R3 now features Yamaha Motorcycle Connect (Y-Connect) smartphone connectivity which works in conjunction with the free-of-charge Y-Connect app (available for iOS and Android) to enable a direct connection between motorcycle and smartphone. Y-Connect capability for the R3 includes the ability to view incoming call, email and message notifications. Additional useful functions include monitoring and notifying the rider or other contact of motorcycle technical issues, and also the ability to track and record key motorcycle ride data within the app, including distance covered, fuel consumption, acceleration, motorcycle location and much more.

IMPROVED ERGONOMICS

A more narrow seat and slimmer side covers improve the rider's foot reach to the ground while retaining the YZF-R3's relaxed riding position.

NEW GENERATION R-SERIES STYLING

Inspired by the flowing aerodynamics of Yamaha's YZR-M1 MotoGP® race bike, the new 2025 YZF-R3's distinctive R-series pedigree is recognizable at a glance with its aggressive new front fairing, sleek new side panels and a sporty new tail section with signature R-series tail wing.

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
- provides an interesting exhaust note
Gear driven "primary coupled-force" balancer shaft.
- reduces engine vibration for excellent rider comfort
Lightweight forged aluminum pistons.
- provide fast engine response
- reduce weight
- reduce mechanical vibration for excellent durability
Carburized connecting rods (carburizing is a form heat treating).
- excellent strength & durability
"Closed loop" 32 mm throttle body fuel injection system.
- system uses an idle speed controller (ISC) to maintain a steady idle regardless of engine temperature
- 12-hole injectors for optimum fuel atomization
- system is tuned to provide excellent rideability and linear throttle control.
- close-loop system uses an oxygen sensor to "sniff" spent exhaust & automatically adjust the fuel / air ratio for reduced emissions
Airbox utilizes a viscous paper-type air filter.
Compact, 6-speed transmission.
- ratios specially designed to suit the character (torque & power) of the engine
- 5th & 6th gears are overdrive gears to reduce engine rpm at highway speeds
Compact, wet-type, multi-plate clutch.
- ensures consistent, positive shifting
- light, easy clutch lever pull.
Low-mounted, 2-into-1 exhaust system.
- utilizes a short design muffler fitted with a 3-way catalyzer to reduce exhaust emissions
- low mounted design centralizes mass for agile handling & lightweight feeling
Maintenance-free transistor controlled ignition (TCI).
- produces a strong spark for fast starts
- provides precise ignition timing / mapping for optimum engine performance at any rpm
Easy access spin-on type oil filter & engine oil drain plug.
- fast & easy oil changes
- oil change interval is 5,000 kms after the initial 1,000 km break-in oil change
Air Induction System (AIS... not ram air).
- reduces harmful exhaust emissions
- injects fresh air into exhaust ports to fully burn any unburnt fuel, further reducing exhaust emissions

Chassis

Lightweight, diamond-type, high-tensile, steel frame
- 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.
