TheHonda VFR800 (Interceptor) is asport touring motorcycle made byHonda since 1998.[1] The model was the successor to theVFR750F and shares theV4 engine configuration with theHonda VF and VFR series.
The VFR800 name was given to three successive iterations of Honda V4 motorcycles:
The VFR800 is only 34 cc greater in volume than the VFR750F but, being wider in bore and shorter in stroke, is both more oversquare and more powerful than its predecessor, with the stroke reduced from 48.6 to 48mm, and the bore increased from 70 to 72mm. Nevertheless, rather than being a direct development of the previous, carbureted VFR750F engine, the VFR800 engine was a detuned power plant based on the fuel-injected engine designed for theRC45 of 1994. The RVF750R RC45 engine, although a development of theVFR750R RC30 and originally derived from theVFR750F RC24, was very different from Honda's previous V4s as the gear drive for the camshafts was moved from the center of the engine to the engine's right-side (next to the clutch-pack).[2] Another change was the two side-mountedradiators as opposed to one at the front of the engine front as on the VFR750. The engine was tuned for road use in the VFR800, so thattorque was improved throughout the rev range while maximum power was only slightly higher than the VFR750.
The VFR800's frame uses the engine as a stressed member, this was derived from theVTR1000 Firestorm, and retains the trademark VFRsingle-sided swingarmpivoted from the aft of thecrankcase. It uses normal 'right-side-up'front forks.
In 2000, Honda updated the fifth-generation VFR (RC46) with acatalytic converter,oxygen sensors, and anEFI system that would enter closed-loop mode under highway (cruising) operation. These also came with a temperature-actuated fastidle system, negating the need for achoke lever. The rear-view mirrors got updated as well, with Honda forgoing the old rubberized stalks, instead opting for rustproof metal ones. Bikes supplied for Europe also came with the H.I.S.S. (Honda Ignition Security System)immobiliser system in an effort to combat theft.[3]
The VFR800 has aCBS linked braking system. This is a departure from traditional motorcyclebraking system where front and rear braking are independent of each other. In this system, the front brake lever applies pressure to four (or later Gen 6, five) of the six frontbrake caliper pistons. The rotational movement of the left caliper when engaged actuates a secondary master cylinder and applies pressure to one of the rear caliper's pistons. The rear brake pedal is directly attached to the remaining pistons (two in the rear, and one or two in the front).
The CBS system is designated "dual" as both hand lever and foot pedal each control both front and rear brakes; commonly, the foot pedal only operates the rear brake. Honda first introduced this braking system on the 1992Honda CBR1000F. It was based on the Unified Braking System that was introduced on the 1983GL1100.
The sixth generation VFR was introduced in 2002. It featured dual underseat exhausts, optionalABS, DCBS linked brakes, and optional hard luggage. It featured chain-driven cams rather than the gear-driven cams of earlier VFRs, and VTEC valve actuation.
In 2006 the VFR 800 received some minor upgrades, which included the change of the tachometer face from black to white, a re-mapped ECU to provide a smoother transition into VTEC, clear turn signal lenses and upgrades to the electrical wiring to fix issues with the charging system.[4]
The VFR800 was phased out after the 2009 model year in the United States, when Honda introduced the largerVFR1200F;[5] but the VFR1200 was not a direct replacement for the VFR800; the true successor being the 2014 VFR800F (RC79).
The VFR800 was the first non-JDM motorcycle to useVTEC valve-gear. Honda used VTEC to meet tightening noise andemissions standards and to increase the peak engine horsepower.Based on theVTEC-E system, the simplified motorcycle version of VTEC employs only two of the four valves per cylinder when operating at lower engine speeds. All four valves per cylinder are engaged above approximately 6,800 rpm. This is initiated by an electronically actuated oil spool valve, which sends oil pressure to the lifter actuators, which then move the engagement pins into place above the valve stem, allowing the remaining two valves to open. This design allows for variable valve timing as well, since the cam lobe profiles can be made different. After much criticism of the abruptness of power transition, Honda lowered the VTEC activation rpm threshold to 6,400 rpm in 2006.[6] The VTEC disengages two cylinder valves when the engine speed drops again below 6,100 rpm.

Afacelifted VFR800 debuted at the 2013EICMA show in Milan, Italy. The revised model features a new single sided exhaust system, akin to the fifth-generation one, lighter wheels, and additional mass-reduction, lowering the curb weight by 10 kg (22 lb). The new VFR also features traction control, a new instrument panel, and revised aerodynamic bodywork with LED lighting, though the engine and chassis remain largely unchanged from the previous sixth-generation model. Continued from the sixth-generation model is also the 2006 refined version of the VTEC system. The side-mounted radiators were dropped in favour of dual front-mounted units.[7] The model is sold worldwide. In the US market, it is available in two versions: Standard and Deluxe. The Deluxe version adds ABS, traction control, grip heaters, center stand, and self-canceling turn signals. Outside the US, only the Deluxe version is sold.[8][9]
