Honda VFR 800


History [ edit ]

its first sales in 1986, the scored highly on many reviews. While it was originally to be a sports bike, the introduction of competitors (including the nearly or 66lb lighter GSX-R750 ) Honda in 1990 to transition the VFR a mid-sized sport touring a category of which the VFR became the de benchmark. However, by 1997, and Ducati presented Honda significant sports-touring competition, so responded with a redesigned in 1998.

Fifth Generation: [ edit ]

Rather than a direct development of the previous VFR750F engine, the VFR800 was a detuned and longer-… power based on the fuel-injected RC45 engine. The RVF750R RC45 although a development of the VFR750R and originally derived from the RC24. was very different as the drive to the cams was moved the centre of the engine to the one side, to the CBR250.

Tuned for road use in the VFR800, injection provided excellent and power was slightly increased the VFR750. The most noticeable however, was that the torque were substantially improved the previous model right up to the red line. All VFR800 models use injection instead of carburetors for mixing.

In 2000, Honda the fifth generation VFR (RC46) a catalytic converter. oxygen and an EFI system that would closed-loop mode under (cruising) operation.

The VFR800 bodywork covered a derived from the VTR1000 It incorporates the VFR trademark single-sided pivoted from the aft of the crankcase. the engine as a stressed member of the

Honda fitted its DCBS braking system. a departure traditional independent front/rear braking systems. In this the front brake lever pressure to four (in later five) of the six front pistons. The movement of the left caliper engaged actuates a secondary cylinder and applies pressure to one of the pistons.

The rear brake is directly attached to the remaining (two in the rear, and one or two in the front).

Sixth Generation: 2002-Present [ ]

The sixth generation VFR (for the time marketed only as the in the USA) was introduced in 2002. For the time it featured dual exhausts, an optional anti-lock system (ABS) in addition to the and optional hard luggage. It chain-driven cams rather the traditional VFR gear-driven cams, and was the motorcycle to have Honda’s valve-actuation technology.

The implementation of was seen as a bid by Honda to meet noise and emissions standards in and abroad while improving the horsepower of the engine. Similar to the version of VTEC-E the simplified version of VTEC employs two of the four valves per cylinder operating at lower engine All four valves per cylinder engaged above 6,800rpm.

This is initiated by an electronically oil spool valve, which oil pressure to the lifter actuators, then move the engagement into place above the stem, allowing the remaining two to open. This design for variable valve timing as since the cam lobe profiles be made different.

It is speculated the duration of valve lift and on the below and above 6,800 RPM differ. After some of the abruptness of power transition, lowered the VTEC activation rpm to 6,400rpm in 2006. The VTEC two cylinder valves when the speed drops again 6,100rpm.

For 2009, there were no changes to the VFR800.

The VFR800 was out after the 2009 model in the United States replaced by the VFR1200F. [ 1 ] However the VFR800 to be sold in international markets 2013.

2014 Revision [ ]

A face lifted VFR800F at the 2013 EICMA show in Italy. The revised VFR800 a new single sided exhaust lighter wheels, and additional reduction lowering the curb by 20kg. The VFR also features control, a new instrumentation panel, and aerodynamic bodywork with LED though the engine and chassis largely unchanged. The 2014 will be sold both in markets and available in the United [ 2 ] [ 3 ]
