Yamaha to include 2018 WR450F in its dirt biking segment with loads of updates

Yamaha has aligned various bikes from different segments for launch in either late 2017 or 2018. It is planning to introduce its one more off-road dirt terrain bike by next year. Its previous model was launched in 2016 which was specifically designed to operate in harsh conditions.

There are some updates and alterations done in the upcoming 2018 WR450F compared to the previous one. The new WR450F gets an electric starter as the kick starter has been eliminated. There is also a minor change at the header pipe which is a small additional guard. It comes with a new right-side panel to cover all the electrics that were exposed in the previous WR450F. The key update is the bike gets upgraded KYB fork with a modification in pressure piston holes and shape with a new setting.

The new 2018 WR450F has also been refreshed with new touch of blue for rims and body graphics.
