2010 Honda VFR1200F Engine Explained | Video
Click video to watch Honda explain the new generation of V-4 technology in the 2010 VFR1200F. The engine includes a unique cylinder layout with rear two cylinders located innermost on the crankshaft and front cylinders located outboard narrows the rider interface aboard the VFR1200F. The V-4 is a light and compact 1237cc liquid-cooled 76-degree V-4 that pumps out amazing levels of power with a distinctive V-4 feel and sound.
To reduce vibration, Honda uses a Symmetrically Coupled Phase-shift Crankshaft with 28-degree crankpin offset to virtually eliminate engine vibration. Asymmetrical exhaust lengths between front and rear cylinders boost power production and enhance power feel. Honda uses a throttle-by-wire system in order to tune the throttle response along with a slipper clutch, in the manual-shift model, to allow for some unencumbered sport riding.
