2. Race-ready Dunlop MX3S tires are now stock. This is a step-up from the previous Dunlop MX51 tires used on the WR450F. If you ride on soft-to-intermediate terrain, you’re set right out of the box. Tire size remains unchanged.3. The e-start 2018 Yamaha WR450F no longer has a kickstarter. The removal saves weight and cost. With the kickstarter gone, Yamaha added a small additional guard for the header pipe.4. There’s a new right-side plastic panel. We didn’t like the exposed electrics on the right side of the WR450F, and someone at Yamaha didn’t either. So, Yamaha added a small cover on the right side to hide and protect them. However, we haven’t seen the WR450F in person and, even after poring over photos of the bike and comparing it to the ’17, we can’t find the panel!5. The 2018 Yamaha WR450F also gets new graphics and the rims are now blue, and the price is unchanged. MSRP remains $8099.6. Everything that we liked about the WR450F remains unchanged. It is the tamed lighting-equipped enduro version of the YZ450FX off-road racer, with the engine tuned for environmental sensitivity.
