Fuel injection, ignition, lambda control, and the throttle valve map are adjusted, resulting in approximately 2 to 3 hp more power, 4 to 6 Nm more torque, and significantly more distinct characteristics between the three mappings, all without the need for additional hardware on the motorcycle.\u003c\/p\u003e\n\n\u003cp\u003eUnlike piggyback modules or auxiliary control units, we modify the stock software directly.

At least as noticeable is the smoother power delivery and the significantly wider character spread between the three maps.\u003c\/p\u003e\n\n\u003ch3\u003eWhy is the stock power not in the table?\u003c\/h3\u003e\n\u003cp\u003eHonda does not provide an official power rating for the CRF 450 R as a competition machine.
