Yamaha revealed the production version of its 250 sportbike, the two-cylinder YZF-R25. Manufactured in Indonesia, the R25 will first be offered in that market before being exported to other markets including other Asian countries as well as developed markets in the west.
The production model stays close to the prototype R25 revealed at the Tokyo Motor Show last fall. The riding position is not as aggressive with higher handlebars than the ones shown on the prototype. The design follows styling cues from the R1 and R6, drawing on the R-series’ lineage.
The R25 is powered by a fuel-injected liquid-cooled 249cc parallel-Twin engine claiming 35.5 hp at a fast-spinning 12,000 rpm and 16.7 ft-lb. at 10,000 rpm. That would give it a power advantage over the Honda CBR300R‘s claimed 30.4 hp at a more sedate 8500 rpm despite giving up 37 hp. The 296cc Kawasaki Ninja 300 still holds an edge, claiming 39 hp at 11,000 rpm, though the R25′s claimed 367-pound curb weight is about 12 pounds lighter than the Ninja’s claimed weight.
The suspension system is comprised of a 41mm telescopic fork and rear monoshock. The 298mm single front brake disc is gripped by a two-piston caliper while a single-piston caliper stops the 220 mm rear disc. The R25 wears a tubeless 110/70-17 tire up front and a 140/70-17 at the rear. The seat is 30.7 inches from the ground and the fuel tank holds 3.8 gallons.
