The Honda VFR800 (Interceptor) is a sport touring motorcycle made by Honda since 1998. [1] The model was the successor to the VFR750F and shares the V4 engine configuration with the Honda 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 the RC45 of 1994. The RVF750R RC45 engine, although a development of the VFR750R RC30 and originally derived from the VFR750F 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-mounted radiators 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 that torque 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 the VTR1000 Firestorm, and retains the trademark VFR single-sided swingarm pivoted from the aft of the crankcase. It uses normal 'right-side-up' front forks.
In 2000, Honda updated the fifth-generation VFR (RC46) with a catalytic converter, oxygen sensors, and an EFI system that would enter closed-loop mode under highway (cruising) operation. These also came with a temperature-actuated fast idle system, negating the need for a choke 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 a CBS linked braking system. This is a departure from traditional motorcycle braking 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 front brake 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 1992 Honda CBR1000F. It was based on the Unified Braking System that was introduced on the 1983 GL1100.
The sixth generation VFR was introduced in 2002. It featured dual underseat exhausts, optional ABS, 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 larger VFR1200F; [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 use VTEC valve-gear. Honda used VTEC to meet tightening noise and emissions standards and to increase the peak engine horsepower. Based on the VTEC-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.
A facelifted VFR800 debuted at the 2013 EICMA 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]

The Honda VF and VFR series is a range of motorcycles first introduced in 1982 by Honda featuring V4 engines.
The Honda Prelude is a sports car produced by the Japanese company Honda over five generations from 1978 to 2001.
The Honda Magna is a cruiser motorcycle made from 1982 to 1988 and 1994 to 2003 and was the second Honda to use their new V4 engine shared with the VF750S Sabre and a few years later a related engine was fitted to the VF750F 'Interceptor', the later models used a retuned engine from the VFR750F with fins added to the outside of the engine. The engine technology and layout was a descendant of Honda's racing V4 machines, such as the NS750 and NR750. The introduction of this engine on the Magna and the Sabre in 1982, was a milestone in the evolution of motorcycles that would culminate in 1983 with the introduction of the Interceptor V4. The V45's performance is comparable to that of Valkyries and Honda's 1800 cc V-twin cruisers. However, its mix of performance, reliability, and refinement was overshadowed by the more powerful 1,098 cc "V65" Magna in 1983.
VTEC is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. The VTEC system uses two camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT systems which change only the valve timings and do not change the camshaft profile or valve lift in any way.
The Honda VFR400 series of motorcycles were a related series of 399 cc V4-engined motorcycles, which were essentially scaled-down versions of the larger VFR race models of the day. They were mainly developed for, and sold in, the Japanese domestic market, in part due to the tougher motorcycle drivers' license restrictions in Japan at the time for motorcycles with displacement exceeding 400cc.
The Honda VFR750F is a motorcycle manufactured by Japanese automobile manufacturer Honda from 1986 to 1997. The motorcycle is a very sporty sport tourer, and is powered by a 750 cc (46 cu in) V4 engine developed from the earlier VF750F models. The VFR was announced in 1986, after an initial press viewing at the 1985 Bol d'Or.
The Honda VFR750R, model code 'RC30', is a fully faired, solo-seat-only racing motorcycle created for homologation purposes for the World Superbike Championship by Honda Racing Corporation (HRC). It was first released to the Japanese market in 1987, released in Europe in 1988 then the United States in 1990. There were only 3,000 made and they sold for US$15,000 - a very large amount for a production bike at the time.
The VF1000 is a range of motorcycles produced by Honda from 1984 to 1988. The VF1000 is named after its V-4 998 cc (60.9 cu in) double overhead cam 16-valve engine. There were three main models in the VF1000 range, the VF1000F, the VF1000R and the VF1000F2.
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
The Honda RVF400R (NC35) was a sport bike manufactured by Honda from 1994 to 1996. It was powered by a 16-valve double overhead geardriven cam 400 cc 90° V4 four-stroke engine, and was known for its handling capabilities.
The Honda CBR1000RR, marketed in some countries as the "Fireblade", is a 999 cc (61.0 cu in) liquid-cooled inline four-cylinder superbike, introduced by Honda in 2004 as the 7th generation of the CBR series of motorcycles that began with the CBR900RR in 1992.
The Honda RVF750R RC45 was a fully faired racing motorcycle created for homologation purposes for the Superbike World Championship by Honda Racing Corporation. The RVF750R was the successor to the VFR750R RC30. Like its predecessor, the RVF750R featured a DOHC liquid-cooled V4 4-stroke engine with gear driven cams and a single-sided swingarm, but unlike the RC30 it utilized electronic fuel injection, in a setup very similar to the production 1992 NR750. The US spec engine had a 749.2cc capacity and was rated at 101 horsepower; the European version was rated at 118 horsepower. A simple rewire modification to the PGM-FI box increased power in the US engine up to the 118 hp. It was manufactured from 1994 until 1995 and sold in limited numbers, followed by the VTR1000R SP-1 RC51 in 2000. Unlike the VFR750R RC30 and VFR750F from which the engine was originally derived the gear drive for the cams was moved from the centre of the engine in between the cylinders to the one side allowing a slightly narrower engine.
The Honda Sabre was a motorcycle made by Honda from 1982 to 1985. Two years of the Sabre production run were part of a group of Japanese motorcycles that came to be known as "tariff-busters". The 1984 and 1985 models fell in this class because of the modifications made allowing those models to circumvent the newly passed United States International Trade Commission tariff that placed a heavy tax on import/foreign motorcycles with 700cc or larger engine displacement.
The VT250 or Spada MC20 is a Honda motorcycle built between late 1988 and the end of 1989.
The Honda VT250F Integra is a semi-faired, sport bike first produced by Honda in 1982.
The sixth-generation Honda Civic is an automobile produced by Honda from 1995 until 2000. It was introduced in 1995 with 3-door hatchback, 4-door sedan and 2-door coupe body styles, replicating its predecessor's lineup. The sixth-generation Civic offered two new 1.6-liter 4-cylinder engines and a new continuously variable transmission (CVT) on the HX model. The coupe and sedan are 2.3 in (58 mm) longer and the hatchback is 4.3 in (109 mm) longer than the previous-generation Civic. This was the last generation of Civic to have front double-wishbone suspension, as the succeeding seventh generation would change the front suspension to a MacPherson strut.
The Honda VFR1200F is the 7th generation Honda sport touring motorcycle from the VF and VFR line motorcycles powered by a transverse mounted V4 engine. The VFR1200F has several new technologies including the first dual clutch transmission offered on a motorcycle.
The Honda CB400 Super Four is a CB series 399 cc (24.3 cu in) standard motorcycle produced by Honda at the Kumamoto plant from 1992 to the present. The CB400 embodies the typical Universal Japanese Motorcycle produced through the 1970s, updated with modern technology. To this end, the bike has a naked retro design, paired with a smooth inline-four engine. Originally a Japan-only bike, it was later also available in SE Asia, and from 2008 in Australia.
Motorcycle braking systems have varied throughout time, as motorcycles evolved from bicycles with an engine attached, to the 220 mph (350 km/h) prototype motorcycles seen racing in MotoGP. Most systems work by converting kinetic energy into thermal energy (heat) by friction. On motorcycles, approximately 70% of the braking effort is performed by the front brake. This however can vary for individual motorcycles; longer-wheelbase types having more weight biased rearward, such as cruisers and tourers, can have a`greater effort applied by the rear brake. In contrast, sports bikes with a shorter wheelbase and more vertical fork geometry can tolerate higher front braking loads. For these reasons, motorcycles tend to have a vastly more powerful front brake compared to the rear.
The XRV650 Africa Twin is an enduro motorcycle produced by the Japanese manufacturer Honda from 1988 to 1989. The enduro is derived from the design of the Honda XL600V Transalp and is powered by the V-twin cylinder engine of the Honda NT650 Hawk.
