Overview[edit | edit source]

Yamaha YZF-R 3







Bred from the ground up using Yamaha R Series DNA the YZF-R3 features a 320cc, liquid-cooled, in-line two-cylinder, DOHC, fuel injected engine tuned to deliver excellent power and performance throughout the powerband.

Legendary R-Series styling with a full fairing gives the YZF-R3 that destined for the racetrack look and the low seat height of 30.7” make it available to a wide variety of riders looking for their first motorcycle or just prefer a lightweight, nimble machine.

The YZF-R3 features top notch components like KYB front suspension, lightweight aluminum 10-spoke wheels and a newly designed compact LCD instrument panel that displays all the important data at a glance.

The YZF-R3 will be available in three color options—Team Yamaha Blue/Matte Silver, Rapid Red and Raven––and will retail for just $4,990, with bikes available in dealerships beginning in March 2015.


Yamaha 2015 YZF-R3 Features Top Features:

Large 321cc twin-cylinder engine offers excellent performance whether navigating cross-town traffic, hitting the twisties, or on the racetrack. Yamaha supersport inspired styling with a full fairing in a chassis that makes it perfect for first time riders or experienced riders who prefer a lightweight, nimble machine. Forged pistons just like the R1 and R6 are both lightweight and provide strength while the offset cylinders reduce friction for more power. The YZF-R3 offers a riding position that is very comfortable and the clip-on handlebars deliver a sporty rider position. With a seat height of only 30.7 inches and a flat seat design on the YZF-R3, it’s easy to get both feet firmly on the ground and inspire confidence, especially for beginner riders. Three beautiful livery options are available which means there is a color choice that is right for you.


Engine:

Newly developed 321cc, liquid-cooled, in-line 2-cylinder DOHC, 4 valves per cylinder, fuel-injected engine delivers excellent power and performance throughout the powerband. With a compression ratio of 11.2:1 the engine develops maximum power at 10,750 rpm for an exciting ride. With a 180 degree crank design the machine provides a compact engine design and superior feeling when accelerating through the rpm range. Downdraft induction fuel injection provides easy starts and smooth performance in all conditions. Yamaha’s all-aluminum DiASil cylinder is used to ensure excellent heat dissipation and the unique design reduces horsepower loss. Forged aluminum pistons, same technology used for the R1 and R6 means lighter weight and excellent strength at higher temperatures while the offset cylinder helps reduce horsepower loss at the point of combustion.



Chassis/Suspension:

Newly designed steel frame and swingarm. Powerful 298mm floating mount front disc brake ensure excellent stopping power while a 220mm floating disc handles the braking performance on the back. 41mm KYB® front suspension offers 5.1 inches of travel for rider comfort and control. 10 spoke cast aluminum wheels are both strong and high in style while reducing unsprung weight. The multi-function meter informs the rider of gear position, fuel capacity, real time and average fuel economy, water temp, clock, two tripmeters and an oil change indicator light.

Additional Features:

Legendary R-series styling and performance are inherent with the YZF-R3. Great styling matched to excellent engine performance and chassis design are the hallmarks of Yamaha’s R-series and YZF-R3 carries on the heritage with great results.



ReviewA first choice of motorcycle is harder than ever in Australia. The adoption of the Learner Approved Motorcycle Scheme (LAMS) means you can ride anything from hundreds of second-hand bikes under 660cc to many, many new ones. With the capacity ceiling higher, the old 250 learner-bike has had a growth spurt to compete with the influx of competition. What used to be a class of 250 machines is now becoming a class of 300s with a couple of models already on the market and more confirmed to come. The 300s released so far have proved to have some big benefits over 250s through a small capacity increase of about 20 percent. Yamaha has come late to the learner sportsbike party, but has come in pushing the capacity of the class to 321cc. That amounts to a 29 percent increase over the YZF-R25 that the R3 has evolved from. Australia didn’t get the 250cc YZF-R25 released in 2014. In some markets a 250cc capacity is essential for licencing and registration reasons. In other markets, like Australia, these two factors don’t influence buying choice. An increase in capacity will always benefit performance. Yamaha had to compete, so instead of bringing to Australia the R25 we get the bigger R3 with the best benefits extra capacity brings with it – more power and torque. The YZF-R3 engine is a new design that takes a few key technologies from the YZF-R1 and MT family. There are light components, forged pistons, strengthed conrods, surface treatment in the cylinder sleeve and cylinders offset to the crank. These are all measures to get the engine spinning up quick, strong in delivery and to achieve its impressive output. And it works. The R3 pulls away from a standstill off the throttle and there is no need for revs or clutch work to get moving in a hurry. There is good control at low rpm and elsewhere through the rev range the response wont catch you out, but it gains revs through to redline impressively enough. There’s no urgency to the R3’s response at high rpm, and to be fair there never is on this class of machine on the road. At over 140km/h there isn’t anywhere to find this out except on track. And that’s just where we got to ride the R3 at the national Australian press intro. It was the perfect place to test the limits of a handling package designed for novices and commuters. Set for a rider around the 80kg mark, both front and rear ends are set firm enough for aggressive riding and worked well on the few bumps the test track had. There’s no flimsiness in this machines design. The steel trellis frame, 41mm KYB forks and rear shock on a long swingarm tye things together. Even with the grippier-than-standard Dunlop rubber, the R3 felt solid on the racetrack. A better rider will find the limitations in its chassis, but it’ll only be a racer that complains and wants more. Front and rear brakes are 300mm discs with ABS. The brakes provided strong power and good feel on the racetrack. The racetrack and grippy tires pushed the limitations of the brakes but on the road this wont happen. The R3 isn’t an intimidating bike to sit on for shorter riders. The seat height is a low and narrow 780mm while at 169kg full of fuel the R3 is light. Taller riders fit on the bike with room to spare. Heavier riders will need to add that extra few clicks of preload as it makes a big difference to the handling dynamic when set right. At just over $6k, there are a lot of reasons why the YZF-R3 is a great machine to start out on. One of them is the fact that the quality of finish is better than it should be for the price. This will pay dividends at resale time. Another is the 10,000km service intervals with 40,000km on the valves. The most important reasons are the engine and chassis that are great to learn with and a lot of fun when you get experienced. The styling is modern and so too is the engine – something not every bike in this class can claim. A new engine design also has big advantages in efficiency and performance. There is a list of genuine accessories including Akrapovič exhaust systems, seat cowls, screens, sliders, luggage and covers too. If you are looking for a race-inspired bike to start out on that oozes street cred, the YZF-R3 has the goods. Better than that, it goes and handles as good as it looks. This bike is just the thing riders starting out need to hone their skills aboard on the road and track right before they step up to bigger capacity machines.
