▸ Yamaha’s 2010 YZ450F was the first incarnation of their now well-known reverse-cylinder motor.
▸ Aimed to enhance Yamaha’s focus on mass centralisation, the “downward draft” design originally ran a Cyclone-type exhaust system, which later changed to a wrap-around header pipe in future years.
▸ The bike found instant success in Australia in the hands of CDR Yamaha’s Jay Marmont, with Jay winning the 2010 MX Nationals title.
▸ Yamaha utilised a bilateral beam frame for the first time on its 450 machine after introducing a similar frame on its 250F.
▸ With the introduction of fuel injection, Yamaha launched its Power Tuner, giving riders more control over their engine's power delivery.
