Difference between revisions of "Honda VFR800"

The sixth generation (RC46) began in 2002 and featured dual underseat exhausts and available ABS (antilock brakes) in addition to the DCBS. It was the first generation of VFR to feature chain-driven rather than gear-driven cams plus VTEC valve actuation technology. In contrast to the automotive version of VTEC, where the cam timing is changed to suit the engine RPM providing a broad spread of power, the simplified motorcycle version employs only 2 of the 4 valves per cylinder when operating at lower engine speeds. All 4 valves per cylinder are utilised above 7000 rpm. These changes were a bid by Honda to meet tightening noise and emissions standards in their home market and abroad. In 2006, Honda has lowered the VTEC activation threshold as the power delivery of the 2002-2005 VTEC models tended to dip slightly before the transition point. In the 2006 edition the VTEC engages at 6400 rpm and stops working when the rpm is back to 6100.
