The Honda VFR1200X borrows the liquid-cooled 76-degree V-Four engine from the VFR1200F. The angle between the two banks of cylinders combined with a 28-degree phasing between the crankpins was designed to eliminate vibration, and the Honda VFR1200X is noticeably calm for a huge V-Four. It features Honda’s Unicam SOHC configuration, which creates more compact dimensions for the 1237cc 16-valve engine by reducing the size and weight of the cylinder heads, and optimizing combustion-chamber shape. Compression was changed slightly from 12.0 to 12.1:1 and performance was reconfigured for more low-end torque. The intake howls, but is not replicated by the exhaust. Aftermarket pipes will be a popular breathing upgrade to make this beast sing.
Honda Selectable Torque Control (HSTC) constantly monitors wheel-speed. When a difference in speed between front and rear wheels is sensed, engine torque is momentarily reduced by a combination of ignition cut and modulation of the throttle butterflies through the throttle-by-wire system. As the difference in wheel-speed decreases, the system shifts into modulating only the throttle butterflies to ensure a smooth transition as the HSTC reduces intervention. The system features three levels of engagement, selectable via push-button, and can be switched off. As a traction control solution, I found it extremely and annoyingly aggressive in its highest setting and preferred to dial it down.
