While Hong Leong Yamaha Malaysia soldiers on with the Yamaha YZF-R25, a fairly capable sports bike in its own right but rather long in the tooth now, here’s a couple we don’t get locally, the 2018 Yamaha YZF-R3 and YZF-R15. While the R3 has been around for some time, the YZF-R15 Ver. 2.0 was recently launched in India.

Both motorcycles were on display on the Yamaha stand at the 2018 Bangkok Motor Show, and paultan.org took some photos for a gallery. The R15 is basically Yamaha’s entry-point into its “real” sports bike range, taking design cues from the bigger bikes in the YZF range.

Power for the YZF-R15 comes from a 155 cc, liquid-cooled single-cylinder power plant with variable valve actuation. The engine is rated at 19.3 PS at 10,000 rpm and 15 Nm of torque at 8,500 rpm, with fuelling by EFI and delivered to the rear wheel via a six-speed gearbox.

A full monochrome LCD display is used for the instrument panel with fuel carried in a 11-litre tank. Suspension uses a conventional telescopic fork with rear monoshock, and single hydraulic disc brakes are fitted front and rear, with wet weight at 139 kg.

As for the YZF-R3, which could be described as a R25 plus, power comes from a 321 cc, liquid-cooled, DOHC parallel-twin with eight-valves, producing a claimed 42 hp at 10,750 rpm and 29.6 Nm of torque at 9,000 rpm. Power gets to the ground via a six-speed gearbox, and the mill is fed by EFI.

A 41 mm diameter conventional telescopic fork props up the end and a KYB monoshock adjustable for pre-load suspends the rear. Brakes are a dual-piston hydraulic calliper in front grabbing a 298 mm disc, with a 220 mm disc at the back, grabbed by a single-piston calliper and ABS is a model option.

Fuel for the YZF-R3 is carried in a 14-litre tank and wet weight is claimed to be 169 kg. In the European market, an extensive catalogue of accessories is offered, including Ohlins fork springs and Akrapovic racing exhaust system.
