Development [ edit ]

The first V4 bike was unveiled at the 2008 show in Cologne. Germany. [ 5 ] [ 6 ] It had design elements that to appear in the production VFR1200F, in the X shaped headlights. Leaks and spy of a new Honda appeared in various including online and print outlets. [ 7 ] [ 8 ] Honda created websites in Fall 2009, in parts of the a new V4 were shown and a countdown timer was displayed. [ 9 ] [ 10 ] years after the introduction of the 6th generation VFR800 Honda the production VFR1200F at the 2009 Motor Show. [ 11 ]

Production [ ]

Production of the VFR1200F began in 2009 and first models delivered in early 2010. [ 4 ] The V4 architecture is kept from VFR models though the engine and are completely new with displacement from 800 to 1200 cubic A slightly de-tuned version of the and the same gearbox, have used on the VFR1200X Crosstourer. a motorcycle launched in 2011. [ 12 ] [ 13 ]

Design [ edit ]

The VFR1200F was designed in Honda’s Italian and design studios under the of Spanish designer Teofilo The exterior features a variety of enhancements taken the Honda bike including a dual fairing designed to pull away from the rider and an X bulbous front nose to the vehicle stable at high as well as increase turn in While the new design was viewed mixed to negative reactions by the public and press, Plaza was by other designers who felt the VFR a new design trend where is the primary design goal aesthetics used to complement the profile of the motorcycle. [ 14 ]

Engine [ ]

The new engine incorporates the single camshaft distribution system Unicam which was tested on offroad machines. This system reduces engine allowing it to be placed further in the frame while lowering the center of gravity. This for better front wheel when cornering.

A 28° positioning of crank pins and a firing order of the cylinders in an engine with perfect balance. Because of this, is no balance shaft. further the engine. [ 15 ]

Instead of conventional mechanical connection from the twistgrip to the throttle, electronic control (throttle by wire) the engine control unit to engine power output.

The of the cylinders is also unique. The V4 has the bank of cylinders paired together, with the big ends of connecting rods on the inner of the crank journals. The forward of cylinders is conversely set outboard of the bank, with the big end journals on the outer sides of the crank

This design allows for a narrower engine at the rear, makes the bike slimmer it contacts the rider, and allows an reach to the ground from the

Transmission [ edit ]

The VFR1200F is with either a conventional manual transmission. or an automatic clutch transmission (DCT). [ 16 ] The DCT known in North America as the or in other markets as the VFR1200D, has clutches, one operating 1st, 3rd and 5th the other operating 2nd, 4th and 6th The dual clutches are able to quickly between gears and can in one of three modes: ‘D’, is a fuel-efficient fully automatic ‘S’, a sports automatic which changes gear at engine speeds; and manual in which the rider changes using paddles fitted to the This gearbox is the first of its fitted to a large capacity although dual clutch are already used in race and performance automobiles. The DCT gearbox characteristics of a conventional manual like engine braking and engagement as the internal components are similar except the clutch is controlled by an electric motor and rather than the rider. [ 3 ]

Both models feature a clutch to reduce wheel during hard engine and a shaft drive system to power to the rear wheel. The drive system is bolted to the on a swinging pivot mount. developed a two part shaft by a spline which allows to flex under load the feel and performance benefits of a chain drive. [ 14 ]

Brakes [ ]

The VFR1200F incorporates the C-ABS braking system sourced the CBR600RR and CBR1000RR sport C-ABS distributes the braking completely electronically sending from the brake lever a separate braking computer the system applies hydraulic to the brakes. Anti-lock brakes now as standard equipment rather optional equipment as they in the previous generation. Though the system is combined, to achieve braking force the rider to actuate both front and brakes as the rear brake one of the six front pistons and the front controls one of the two rear pistons. [ 3 ]

Reception [ edit ]

Reactions to the VFR1200 were mixed at its Some had expected a return of the VFR to its past because of a much sport focused concept along with V4 engine sourced from the Honda MotoGP bike. Others Honda continued its tradition of the VFR line to showcase new technologies: the VFR800 was the first production to feature anti-lock brakes and motorcycle version of VTEC. and the new became the first production to feature a DCT automated manual Traction control was added to all models at no additional cost it was not available on first year [ 17 ]

The reduction in fuel tank from 22L (4.8impgal; 5.8USgal) on the VFR800 down to 18.5L 4.9USgal) on the VFR1200F has been the complaint raised by motorcyclists, with the new engine’s higher-than-expected consumption. On-road tests shown a maximum distance a single tank of less 300 kilometres (186mi), [ 18 ] with press reviewers running out of after just 240 kilometres [ 19 ]
