YAMAHA FJR 1300

2012 Yamaha FJR1300 Features and Benefits

ENGINE

1298cc, DOHC, 16-valve, liquid-cooled in-line four engine delivers serious power and torque (99.1 ft-lbs of torque @ 7000 rpm) for an unequalled spread of muscle over a wide RPM range. Red line is a surprisingly low 9,000 rpm for extended engine life.

Engine is a fully stressed chassis member, allowing for a lightweight yet rigid frame design for excellent handling.

One-piece cylinder and upper crankcase assembly provides tremendous engine rigidity that’s lighter and stiffer than two-piece designs.

Specially designed four-valve per cylinder head features compact, side-driven double-overhead camshafts providing outstanding low to mid rpm torque and horsepower for effortless sport touring and great passing power.

Specially designed high lift intake and exhaust cams provide excellent torque and power characteristics well suited to sport touring.

Ceramic composite cylinder “bores” are a “liner less” design with the ceramic coating applied directly to the aluminium block to ensure uniform heat dissipation for consistent power delivery, reduced oil consumption, reduced friction and reduced weight.

High performance, short skirt, forged aluminium pistons are light weight for fast throttle response and also reduce reciprocating mass for less mechanical vibration. Compression ratio is 10.8:1

Specially designed, low-vibration crankshaft features two gear-driven secondary counterbalancers delivering a smooth ride, which enhances both rider and passenger comfort.

The crank uses carburized connecting rods for excellent strength and durability. Carburizing is a heat treating process that increases the carbon content on the outer surface of the rod increasing its strength and durability.

Automatic cam chain tensioner reduces both maintenance and engine mechanical noise.

Advanced electronic fuel injection (EFI) system is ideal for long-distance sport-touring. The 42mm throttle body fuel injection system with 4-hole Nippon injectors delivers crisp, seamless throttle response regardless of weather or altitude. This is a closed loop fuel injection system, with an oxygen sensor that monitors the amount of oxygen in the spent exhaust gases and adjusts the fuel -air mixture via the ECU and FI system for maximum performance with minimum emissions. The benefits of fuel injection include choke-free starting, steady idling during warm up, excellent fuel economy, and reduced emissions. The oxygen sensor is located before the mufflers, so the use of slip-on mufflers will not affect this system.

Heated oxygen sensor provides precise fuel – air ratio information to the fuel injection system to reduce emissions even further, especially at lower engine temperatures.

Compact engine design uses a stacked “Tri-Axis” transmission (transmission shafts are stacked to minimize powerplant size front to back). The stacked design reduces engine length and centralizes mass, thereby allowing the engineers the ability to place the engine in the “sweet spot” of the frame for optimized front and rear weight distribution which provides excellent handling characteristics.
