The VFR has existed since 1985 and its design continues today. This is (almost) even for the displacement. So it has remained as a object of utility, less suitable for exceptional high performance. This also shows the torque value, which will be achieved beside a light increase now at less speed.
The rare V 90° four-cylinder engine uses the VTEC system, which changes the valve control from a certain speed. This switchover point was frequently reason for criticism in the past. Now it has been shifted somewhat up and weakened the performance boost slightly. Motorcycles react just very sensitive to non-continuous power output during acceleration. That's probably because of the now achieved enormous power to weight ratio.
The motor is still to be noted that it has less emission since its move to direct injection and currently is certified (2006) to Euro 3. It has a catalytic converter with Lambda control and secondary air injection.
