Model Name:YZF-R25
Manufacturer:YAMAHA
Model Year:2014
[Newly developed engine with water-cooled structure, DOHC, straight two-cylinder, 4 valve, and fuel injection]
This engine demonstrated its maximum output at 12000r/min and its maximum torque at 10000r/min with its 60.0 x 44.1mm bore stroke and 11.6:1 compression ratio. It adopted the directly actuated valve drive system and the aluminum forged piston to reduce the vibration. It also had the off-set cylinder to minimize the horsepower loss and the DiASil Cylinder to reduce the weight. It achieved superior output and torque characteristics, and well-balanced performance both at low-mid speed range and mid-high speed range.
[Highly rigid diamond frame]
It adopted the diamond frame, created from the latest analytic technology, that was both light and rigid. This frame also enabled the rider to put his feet in a comfortable position.
[Unique three colors]
It came in three colors. One was Deep Purplish Blue Metallic C (blue/silver) that was designed to give the impression of the new global Yamaha Racing blue. Another one was Back Metallic X (black) which gave the impression of cool street riders. And the last one was Vivid Red Cocktail 1 (red/white) which assumed the passionate & casual impression of street riders.
