The new bodywork covered a frame derived from the [[Honda VTR1000|VTR1000 Firestorm]]. This incorporates the VFR trademark of a single-sided swing-arm [[Pivot|pivoted]] in the rear of the crankcase, thereby using the engine as a stressed member of the frame. Handling is described by some as impeccably neutral. | The new bodywork covered a frame derived from the [[Honda VTR1000|VTR1000 Firestorm]].

The [[Brake|braking]] system departed from the normal front and rear independent arrangement and Honda fitted their DCBS (dual-combined braking system). In this system, squeezing the front brake lever applies pressure to four of the six front [[piston]]s. The rotational movement of the left caliper, when braking, actuates a secondary master cylinder which applies pressure to one of the rear pistons. The rear brake pedal is directly attached to the remaining two rear pistons and two front pistons. This arrangement irritated some but was praised—in some circles at least—for removing [[fork dive]] under heavy braking. When Honda released a new generation of VFR in 2002, the DCBS was modified to be less "linked". With the new DCBS, the front brake lever now activates five of the six front pistons and the rear brake pedal activates the two rear pistons and only one front piston. The secondary master cylinder (which is actuated by the rotational force of the front left caliper under braking) remained unchanged continuing to activate one rear piston. | The [[Brake|braking]] system departed from the normal front and rear independent arrangement and Honda fitted their DCBS (dual-combined braking system).

Unlike its VFR predecessors, all VFR800 models use [[fuel injection]] instead of [[carburetor]]s for fuel-air mixing. In 2000, Honda updated the fifth generation VFR with a [[catalytic converter]], oxygen sensors and an EFI system that would enter closed-loop mode under highway (cruising) operation. | Unlike its VFR predecessors, all VFR800 models use [[fuel injection]] instead of [[carburetor]]s for fuel-air mixing.
