For 2012, Kawasaki KX450F receives nifty enhancements. This motocross bike is now loaded with even more factory-inspired components, such as the revised piston and ECU, a new frame, now made from both cast and extruded aluminium elements, a top-drawer fuel injection and pump system, capable to withstand all sorts of racing abuse and a 4-way adjustable handlebar.
The bike sports three standard engine mappings which can be easily switched to by simply connecting the corresponding couplers. However, the KX FI Calibration Kit lets the experienced rider fine-tune the bike to obtain the perfect response. Even more, riders can activate the Launch Control mode with just a press of a button and enjoy the factory-specced engine mapping that provides the best starts: maximal power and thrust with minimal wheel slip.
