History

The Honda VFR 1200F is a sport touring motorcycle category of the Japanese manufacturer Honda.

The fully enclosed motorcycle was on 23 Presented in October 2009 at the Tokyo Motor Show, and 2010 as the successor to the VFR 800 FI or the CBR 1100 XX Blackbird established in the market. Production began in October 2009 in Kumamoto, Japan under the factory code SC63.

The Honda VFR 1200F is a sport touring motorcycle category of the Japanese manufacturer Honda.

The fully enclosed motorcycle was on 23 Presented in October 2009 at the Tokyo Motor Show, and 2010 as the successor to the VFR 800 FI or the CBR 1100 XX Blackbird established in the market. Production began in October 2009 in Kumamoto, Japan under the factory code SC63.

The liquid-cooled four-cylinder engine produced from 1237 cc engine rated at 127 kW (173 hp). Above a speed of 4000 min-1 to nominally 90 percent of peak torque available.

The transversely mounted V-engine comes up with a technically unusual cylinder arrangement: the cylinder bank angle is 76 ° instead of the usual 90 °, the two rear cylinders are arranged in the center, the front cylinders are placed on the outer side. In order to achieve an optimum mass balancing a firing interval was chosen by 28 ° (calculated: 180 ° firing interval angle equal to minus twice the cylinder → 180 ° – 2 × 76 ° = 28 °).

In contrast to the usual uniform 180 ° firing order (180 ° firing interval) two cylinders are fired in rapid succession with 104 ° spacing (so-called big-bang principle) here. Due to this combination of cylinder angle firing interval and firing no balance shafts against unwanted vibrations are needed. The space-saving Unicam valve control with a chain driven camshaft per cylinder bank operated via tappets directly via two intake valves and two exhaust valves per cylinder Roller.

The engine builds despite 455 cc more displacement only slightly higher, and substantially shorter than the 90 ° V4 engine VFR 800 The four cylinders have a bore diameter of 81 mm, a stroke of the pistons of 60 mm at a compression ratio of 12:1.

The bike accelerates in 3.0 seconds from 0 to 100 km / h in 8.9 seconds to 200 km / h and reaches a top speed electronically limited 250 km/h.1

The average fuel consumption is 5.9 liters per 100 km at a speed of 130 km / h The fuel tank has a volume of 18.5 liters. The manufacturer recommends the use of unleaded motor gasoline with an octane number of at least 95 octane and gives a theoretical range of 314 km, at. The exhaust gas treatment is performed by a regulated catalytic converter and below the emission limit values ​​of the emission standard Euro-third

The motor controller (german Engine Control Unit ECU) controls the injection pressure, injection time and the ignition as a function of engine speed, gear and the coolant temperature. In addition, the signals for the actuators of the throttle valve are calculated using a control unit that generates the throttle potentiometer. This technique, which requires no throttle cables, and is drive-by-wire or in this case called Throttle-by-wire.

At the same time, the ECU takes care depending on the throttle position to the actuator for the valve in the upper mouth of the muffler that opens 5000-6000 min-1 and provides a sudden power delivery.

For the first time in a production motorcycle is optionally available for the VFR 1200F a dual clutch transmission (eng. dual clutch transmission, DCT). Unlike the car, the transmission selects not on the gear shaft-load the next gear before, but only switches when the driver or the automatic function gives the order. A switching process takes 500 ms on much longer than current cars with Doppelkupplungsgetriebe.2, but the Honda DCT can suddenly taken off the gas and then downshift to react faster than a car double-clutch gearbox.


The front wheel is delayed by two radially mounted six-piston fixed caliper brakes, the braking forces are transmitted via two floating brake discs with a diameter of 320 mm. The rear wheel is braked by a two-piston floating caliper, brake disc has a diameter of 276 mm. Front and rear brakes work in conjunction, controlled by a common pressure modulator. When operating the hand brake lever of the six-piston brake caliper and four right of the left to move.

Upon actuation of the foot brake pedal, the piston of the two rear brake caliper and, in addition, controlled with the ABS pressure modulator with solenoid control valves, with the upper piston of the two driven front left caliper.

In the low-maintenance shaft drive swingarm is integrated. The pivot pin is positioned above and behind the front universal joint propeller shaft, the shaft therefore does not run exactly parallel to the longitudinal axis of the swing arm. A sliding piece at constant velocity joint before the Tellerradgehäuse secures the compression and rebound of the rear wheel to the required length adjustment of the propeller shaft.

Three shock absorbers have been integrated in the drive train on the shaft between the clutch and the transmission output shaft and the universal joint before. The swingarm is based on a progressive lever linkage and a central spring strut from the frame.

The starter battery has a capacity of 12 Ah and supplies the electric starter. The dynamo generates an electric power of 570 watts.

In the model year 2012 the engine characteristics have been optimized and reduced fuel consumption by changes in the PGM-FI fuel injection. The tank volume was enlarged and modified the seat and the LED mirror turn signals. Traction control was added and optimizes the electronic control of the optional dual clutch transmission.

The machine is available in three variants painting 2010:

The machine was offered in 2012 in four finish versions:

The front merges into the side panel, which in turn merges with the tank. Flow-optimized, lots of wind protection, stable high-speed position. Ideal conditions. But fans of the legendary CBR1100XX Super Blackbird will be disappointed, because the VFR utilizes its possibilities only to a maximum of 250 km / h

With the new VFR 1200 F Honda has provided a technology platform on the 17-inch wheels, which successfully bridge the gap between sport and tour kicks as V-man, but it clearly emphasizes the sporty side. Quality meets the high demands of the VFR tour clientele, which is equal to three-year warranty and customer-friendly 12,000 km extended maintenance intervals underscore.

The long-awaited VFR has become a good bike, very good even. An excellent but it is not. The multi-performance characteristic is more of a hindrance, the sparse features. The 1200s shines through many technological specialties.

In addition, three-year warranty and service intervals 12000. The engine characteristic is unbalanced, the driving befitting only beyond the 4,000 mark. Under 3000 rpm, there is atypical for this displacement class before listlessness.
