Yamaha FZ6R Engine

Here the features of Yamaha FZ6R Engine

• With its heritage firmly rooted in the power plant from an earlier generation R6, the engine in the FZ6R has been carefully updated to meet the demands of today’s motorcyclist. This new engine optimizes the entire flow from the intake of the fuel-air mixture to combustion and exhaust. The cylinder head, crankcase, intake and exhaust system, and clutch and shifter have been completely redesigned, creating a power unit with an entirely new character, even though it shares bore and stroke dimensions and compression ratio with the previous FZ6.


• 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 9000 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. Because the aluminum alloy is heated and formed under pressure without having to melt it completely as in conventional casting techniques, the strength of the original metallurgic matrix of the aluminum is maintained. As a result, a forged piston is stronger than a cast one and can thus be designed for lighter weight, which contributes to a reduction in vibration. In fact, many riders will be surprised at how smooth this motor is.

• The 32-bit ECU controls the four-hole, two-direction, high-dynamic-range type fuel injectors for superior injection control. By delivering the precise fuel-air mixture needed for conditions, the engine can deliver better power and better fuel economy.

• Much like many of today’s high end sport bikes, the FZ6R has a 4-into-2-into-1 midship exhaust. Not only does it provide a throaty, yet comfortably quiet exhaust note, the system also includes 3-way catalytic converter technology to reduce exhaust emissions.
