The Honda VFR800 inherited its position as class leader in the sports-touring sector from its 750cc predecessor. Although its roots go back to the first VF750 of 1982, the latest VFR800 is one of the most accomplished and advanced motorcycles produced.
The V-4 engine at the heart of the VFR uses a VTEC variable valve system which alters the valve opening behaviour to give different power characteristics depending on engine speed. Below 7000rpm, only two of the four valves in each cylinder are opened by the camshafts. This two-valve layout gives superior torque and power production at low revs, where intake gas velocity is more important than large valve time-area values. But at higher revs (above 7000rpm) a computer-controlled valve pushes locking pins into place.motorcycle fairings
