Riding in a High Wind
Nothing new here! Read the section called 'Position' again. If your upper body is relaxed and your arms are bend and loose, the blasting wind will not be able to transfer movement via your arms to the handlebars. Allow your lower body to grip and lean the bike slightly into the wind while your upper body moves about in a fluid-like motion as the wind buffets you this way and that.
While the throttle is open it keeps the bike punching through the air. If however you are hit by a blast of air your natural reaction is to snap the throttle off . . . don't do it! React by gripping the bike even harder with your inner thighs and relaxing your upper body. Perhaps even feather the throttle closed slightly but do not shut it off. If you do, the wind will push you across the road. It is like a rugby scrum - the wind is pushing you, the open throttle is pushing back. If you stop pushing, the wind will get its way.
Also pay careful attention to the trees, grass etc at the side of the road. If they are waving about wildly but you cannot feel the blast, then this is a signal to grip the bike tightly with your inner thighs and relax your upper body in anticipation.
In a wild wind ensure that you ride in the middle of your lane. This give you real estate to work with as your line will naturally wander from side to side as the wind increases and decreases. Be aware that you have your limitations and know when to throw in the towel, pull to the side of the road and wait for the wind storm to pass.
