YAMAHA’S NEW ELECTRIC-START YZ450FX

 

Yamaha announced some of its remaining 2016 models this week at the Marconi Automotive Museum in Tustin, California. The big news for the off-road world was the introduction of two new 450s based on the YZ450F motocross bike. One was the widely predicted update of the WR450F trail bike. The other was the hoped-for YZ450FX.

The WR has the same engine layout as the YZ450F, including the reverse cylinder head layout and the Keihin fuel injection. The WR has suspension, gear ratios and power delivery designed for trail use, as well as a headlight, a radiator fan, an 18-inch rear wheel, a kickstand and it meets the emission requirements put forth by EPA and CARB. The biggest news is the electric starter, which sits in front of the motor. The WR is a trail bike with a very quiet exhaust note. The YZ450FX, on the other hand, is an off-road race bike. It was designed with cross-country racing in mind, although it is imported under the rules that state it’s for closed-course competition. The FX doesn’t meet emission regulations, is not green-sticker legal and is in full-race tune. The suspension is stiffer than that of the WR, but it’s still set up for off-road use, not motocross. This model doesn’t get the headlight or the radiator fan, but it does have the electric starter. As it turns out, this is the same basic motor that Roman Febvre used to win the 2015 World Motocross Championship.His motor might have looked somehat different, but the changes were only superficial outer engine cases that were fabricated by the Italian race team. Unlike Febvre’s bike, the WR and the FX have a kickstart lever for back up.

Yamaha released the 250cc versions of these bikes last year with great success. The new 450s now join those bikes as well as the YZ250X two-stroke that was announced in July, giving Yamaha the most extensive line of off-road bike of any Japanese manufacturer. The WR450F will have an MSRP of
