The Yamaha YZF-R3, commonly known as the "R3", is a sport motorcycle that has been manufactured by Yamaha since 2015. A first for Yamaha twins, the other being R25, the R3 uses an offset cylinder design.[7]

The YZF-R3 was updated for 2019.[8]

Design

The Yamaha R3 is an entry level sport motorcycle,[9][6]designed to compete with rivals in 300 cc sector, such as the Kawasaki Ninja 300, Honda CBR300R, and KTM 390 series. It is designed as a well-balanced sport motorcycle, with some design similarity to R25, such as engine (which is bored out).[10] With a low seat height, the windscreen sufficiently deflects the wind overhead.[11] The 321 cc performance-oriented engine is lightweight, powerful, and has a wide power band. Most of the power can be found from 7,000 rpm to redline (12,500 rpm approx.).[11][9] The engine uses a downdraft induction fuel injection system and the 10-spoke cast aluminum wheels reduce unsprung weight.[12] The cylinders are all-aluminum. For 2017, the YZF-R3 offers optional ABS.[11][9] The 2018 Model has dual channel ABS and is EURO IV compliant.[13]

Performance, reviews and criticisms

The bike can reach 0–60 km/h (0–37 mph) in less than 3 seconds, and 0–100 km/h (0–62 mph) in 5.5 seconds.[14] The 2015 R3 has a braking distance of 131.5 feet from 100–0 km/h (62–0 mph). According to some reviewers, the braking system is not powerful enough to match the engine power, and is also prone to fishtailing under hard braking (non ABS).[9][15] However, engine braking can be used to assist deceleration, as the stock bike does not have a slipper clutch.[10] Minimal adjustable suspension is considered another downside on the bike.[16] However, compared to other bikes in its class, it is considered finely tuned and sufficient.[11]

Rivals

Yamaha R3 competes directly with Kawasaki Ninja 300. Other entry level (sub-400 cc ) competitors include Honda CBR300R,TVS Apache RR310 and KTM RC 390.[17]
