Introduction

Hondas much loved and highly respected VFR debuted in 1986 as the advanced aluminium-framed VFR750F Super Sport, and has seen several evolutions of its design and specifications since then, culminating in the stunningly styled, high performance VFR and VFR-ABS sports touring masterpieces released in 2002 and now still in production. Especially popular in Europe, the VFR has consistently been hailed as Hondas premier high-tech sports model, a position crowned by its current version, which features Hondas innovative V4 VTEC valve actuation system. Designed to bring together the superb low-to-midrange torque associated with 2-valve engines and the roaring surge of high-end power produced by the most advanced 4-valve engines, this system automatically switches between 2-valve and 4-valve operation for a unique combination of performance characteristics, and a wide band of exhilarating acceleration with every twist of its throttle. The VFR has always been know as a well-rounded sports bike that can slice effortlessly through twisty mountain backroads with the fastest Super Sport machines around. However, over its last two generations, as bigger, faster and more singleminded Super Sport models have come to the fore, the VFR has won a growing following as an excellent sports touring bike that can cover long distances in comfort and still deliver exhilarating Super Sport-level performance whenever desired. This peerless combination of performance and comfort has endeared it to a broad crosssection of discerning riders who know and appreciate its high level of quality and broad accessibility.

Engine

The VFRs 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. When the VFR was reborn in 2002 as a more dynamic and formidable sports tourer, 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, all while maintaining the VFRs traditional Honda V4 power characteristics.

Revised V4 VTEC Valve Timing

For 2006, the VFRs high-performance V4 VTEC system has been fine tuned for smoother and more effective shifting between its 2-valve and 4-valve operating zones. 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, while the sound of its characteristic leap in response continues to excite. The engine speed shift zone has also been reduced from 6,800rpm to 6,600rpm, for more comfortable access to the VFRs full 4-valve performanc
