2015 YAMAHA FZ-09, Key Features847cc liquid-cooled, in-line 3-cylinder, DOHC, 12-valve engine with fuel injection. This FZ-09 engine combines advanced high tech components including YCC-T and Yamaha D-Mode, with a crossplane concept crankshaft to deliver an exciting, torquey and quick-revving engine character.“Crossplane Crankshaft Concept” provides linear torque development in response to the rider’s throttle input. Among the advantages of the in-line 3-cylinder engine are: (1) linear torque development, (2) even firing intervals that provide smooth torque characteristics and a good feeling of power in the low to mid rpm range, (3) a light, slim and compact design, and (4) performance that combines the characteristics of both 2-cylinder and 4-cylinder engines.A 6-speed transmission has been adopted to match the engine. The transmission has optimized gear ratios that help to deliver engine torque efficiently. The result is a transmission that helps bring out more of the low- to mid-speed torque and excellent response characteristics.The ride-by-wire Yamaha Chip Controlled Throttle (YCC-T) system senses the slightest throttle input by the rider, relays the data to the ECU, which instantaneously calculates the ideal throttle valve opening based on engine rpm and throttle opening, and then sends commands to a servo-motor actuator that moves the throttle valve which actively controls the intake airflow volume. This is a technology contributing to the rider’s feeling of torque and controllability from the 3-cylinder engine.The FZ-09 is equipped with Yamaha D-MODE (or “Drive Mode”) variable throttle control system to allow the rider to choose the optimum engine character for their riding situation. The rider can choose at will from three throttle valve control maps (Standard Mode, “A” Mode, and “B” Mode) for different performance characteristics. Operation is performed by a button on the handlebars. STD Mode is set to accommodate a wide range of riding conditions. In this mode the rider can enjoy the 3-cylinder engine’s linear torque feeling from low speeds all the way up to high speeds. A-Mode lets the rider enjoy sharper throttle response in the low-to mid-rpm range than the STD Mode. B-Mode lets the rider enjoy milder throttle response than the STD Mode for more relaxed power characteristics.Engine Features847cc liquid-cooled 4-stroke, in-line 3-cylinder, DOHC, 4-valve engine with downdraft intake and fuel injection. With a 78 x 59.1mm
2015 YAMAHA FZ-6R, Key FeaturesA rider in the market for an entry level or commuter 600cc bike doesn’t have to compromise performance or style to get value. The FZ6R is a great combination of performance, handling, and exciting sport bike style, but also with a low seat height that’s both adjustable to fit a wider variety of riders and also narrower where it counts to make it even easier to put both feet on the ground.The engine delivers smooth power just the way today’s rider needs it, brisk acceleration with plenty of torque that makes it a pleasure to get around town, with lots in reserve for when you want more. This is certainly not a “no frills” motor. Its derived from the FZ6 motor, fuel injected and tuned for outstanding low to mid engine performance.Even if your primary goal is commuting to school or work, you want to be able to get out and have fun riding some twisty back roads. The FZ6R is ready to put a grin on your face! The diamond-shaped frame, made of high-tensile steel pipes using the engine as a structural member of the chassis, becomes the foundation for handling performance. It’s designed to provide the right rigidity balance to contribute to smooth cornering performance.When it comes to putting power to the pavement, the FZ6R uses nothing less than quality radial tires, 120/70R-inch front and 160/60R 17-inch rear. And this bikes excellent stopping performance is due to the dual 298mm front discs and 245mm rear disc, both with comfortable-to-use controls.Engine FeaturesThe fuel-injected engine in the FZ6R has been designed to meet the demands of today’s motorcyclist. This engine optimizes the entire flow from the intake of the fuel-air mixture to combustion and exhaust. Even though it shares both bore and stroke dimensions with the FZ6, the cylinder head, crankcase, intake and exhaust system, as well as the clutch and shifter, were completely redesigned for the FZ6R, creating a power unit with an entirely different character.The 600cc liquid-cooled 4-stroke in-line 4-cylinder engine is ready to respond with smooth, linear performance when the rider twists the throttle. Maximum output is achieved at a spirited 10,000 rpm and maximum torque is obtained at 8,500 rpm. Bottom line: Its outstanding “torquey” low to mid rpm engine performance is just right for someone who enjoys commuting to work or school or riding the canyons on the weekends.Lightweight forged aluminum pistons are used.
