INTRODUCTION
For 20 years now, Honda's world-renowned VFR has consistently been
hailed as one of the finest all round motorcycles of any displacement
DEVELOPMENT CONCEPT
The VFR has played an important role in Honda's impressive sports touring lineup, providing one of the finest balances of top performance and
overall riding comfort to be found on two wheels
In the four years since its latest evolution, the VFR's development team has duly noted detailed points where improvements could be made, and set
about to firm up this high technology flagship's position of distinction in its class.
Honda's VFR800 continues to offer a unique fuel-injected V4 engine that produces a band of strong, accessible power through a two stage valve
actuation system.
HONDA'S FAMED V4 ENGINE
The VFR’s famed V4 engine has garnered a proud history of delivering strong, high-revving performance that translates into one of the most
exceptional power deliveries in its class.
Its unique, high-performance V4 engine was completely revised with a new V4 VTEC valvetrain configuration that achieves a remarkable
combination of the stronger surging low-to-midrange power output of a 2-valve engine coupled with the high-revving, power-packed performance of
4-valve top-end.
This new 2-stage valve actuation system also provides the added benefits of lower noise and lower emissions
During hard acceleration, the physical jolt of the engine when coming onto full 4-valve operation has been reduced for a more natural feeling of
surging performance
The engine speed shift zone has also been reduced from 6,800rpm to 6,600rpm, for more comfortable access to the VFR’s full 4-valve
performance.
The speed at which its valve actuation reverts to 2-valve operation has also be lowered to 6,100rpm for a wider range of engagement that helps
minimise any potential for cogging between the two zones of operation.
the PGM-FI fuel injection system’s ECU and injectors (taken directly from the CBR1000RR Fireblade) were also modified to achieve improvements
in driveability while further enhancing the VFR’s sporty feel.
