The Honda VFR800 is the first fuel injected motor sport manufactured by Honda in 1998, since 2002 in the United States also called Interceptor . This model is the successor to the VFR750F and shares the configuration of the V4 engine with the entire family of Honda VF and VFR.

Generasi Kelima: 1998-2001 VFR800Fi (RC46)

Instead of being a direct development of the previous VFR750F carburetor engine, the VFR800 engine is a detuned and longer-stroke power plant based on a fuel injection engine designed for RC45 in 1994. The RC45 RC45 engine, despite the development of the VFR750R RC30 and originally from VFR750F RC24, very different from the previous Honda V-4 because the gear drive to the cams was moved from the center of the engine to one side, similar to the CBR250. Another remarkable change is the two heat exchangers mounted on the side not on the front of the engine on the VFR 750. Set for road use in VFR800, torque is improved throughout the round span while maximum power is only slightly higher than VFR750.

In 2000, Honda updated its fifth generation VFR (RC46) with a catalytic converter, oxygen sensor, and EFI system that would enter a closed-loop mode under highway operation (roaming).

The VFR800 frame, which uses the engine as a stress member, comes from VTR1000 Firestorm, maintaining a one-sided VFR swingarm trademark though, spinning from the rear of the crankcase. It uses a normal 'right side' front fork.

Double combined braking system (DCBS)

VFR800 has a new DCBS connected braking system. This system is a departure from the traditional motorcycle braking system where front and rear braking are independent of each other. In this system, the front brake lever applies the pressure to four (or newer, five) of six piston front brake calipers. The rotation movement of the left caliper as it moves moves the secondary master cylinder and applies pressure to one of the rear caliper pistons. The rear brake pedal is directly attached to the remaining piston (two on the back, and one (or two) in front).

DCBS system designed "Double" for both hand levers and foot pedals respectively controlling the front and rear brakes; while generally the foot pedal only operates the rear brake. Honda first introduced this braking system on Honda CBR1000F 1992. It is based on the Integrated Braking System which was introduced in 1983 GL1100.

Sixth Generation: 2002-2013 VFR800 VTEC (RC46)

The sixth generation VFR was introduced in 2002. Equipped with dual exhaust, optional ABS, DCBS-connected brakes, and optional luggage. It features chain-driven cams rather than the gear-driven cams of the previous VFR, and VTEC valve actuation.

The VFR800 was removed after the 2009 model year in the United States, when Honda introduced the larger VFR1200F; but VFR1200 is not a direct replacement for VFR800; the actual successor is 2014 VFR800F (RC79). The RC46 model of VFR800 continues to be sold in certain international markets.

VTEC valve actuation

VFR800 is the first non-JDM motor to use VTEC valve-gear. Honda uses VTEC to meet the tightness of noise and emission standards and to increase peak engine power. Under the VTEC-E system, a simple motorcycle version of VTEC uses only two of the four valves per cylinder while operating at lower engine speeds. All four valves per cylinder move above about 6,800 rpm. It is started by an electronically activated oil spool valve, which sends oil pressure to the lifting actuator, which then moves the engagement pin into place above the valve stem, allowing the two valves to remain open. This design allows variable valve time settings as well, since cam lobe profiles can be made differently. After much criticism of the sudden power transition, Honda lowered the VTEC rpm threshold to 6,400 rpm in 2006. VTEC releases two cylinder valves when engine speed falls again below 6,100 rpm.

Eighth Generation: VFR800F 2014-Now (RC79)

A facelifted VFR800 debuted at the EICMA 2013 event in Milan, Italy. The revised VFR800 features a new one-sided exhaust system, lighter wheels, and additional mass reduction, reducing the weight of the pavement by 10 kg. The new VFR also features traction control, new instrument panel, and revised aerodynamic bodywork with LED lights, although engines and chassis are largely unchanged from the previous sixth generation model. VFR800F 2014 is expected to be sold worldwide. In the US market is available in two versions, Standard and Deluxe. The deluxe version adds ABS, traction control, grip heater, self-reversible turn signal. Outside the US, only Deluxe versions are sold.
