Description

Design

The Yamaha R3 is an entry level sport motorcycle in the same range as other 250–400 cc motorcycles like the Kawasaki Ninja 300, Honda CBR300R, and KTM 390 series. It has some design similarity to the R25, such as the engine. The engine uses a downdraft induction fuel injection system, and the 10-spoke cast aluminum wheels reduce unsprung weight. The cylinders are all-aluminum. For 2017, the YZF-R3 offers optional ABS. The 2018 Model has dual channel ABS and is EURO IV compliant.

Performance

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).
