I would compare VT650 to Harrop since the price is the same. The VT650 makes more horsepower and the same or more torque but the torque bump starts at higher rpm. Maybe one day a stage II Harrop will be released that bridges the gap, but that has not happened yet despite years of talk. The later boost of the centrifugal actually suits the available octane better given the high compression motor.

The VT650 will spank the Harrop in a drag race. The Harrop should spank the VT650 in lazy daily driving.
