I took a bike safety class that tried to explicitly teach countersteering (I guess the way that I hear motorcycle safety classes do). The instructor&#x27;s theory was that you do always countersteer on a bike but that you usually don&#x27;t notice (unlike motorcycles, I guess). He said that you may need deliberate, practiced countersteering to make a sharp, high-speed turn (called a &quot;quick turn&quot;).<p>It looks like other cycling instructors teach this too:<p><a href="http:&#x2F;&#x2F;www.bamacyclist.com&#x2F;articles&#x2F;QuickTurn.htm" rel="nofollow">http:&#x2F;&#x2F;www.bamacyclist.com&#x2F;articles&#x2F;QuickTurn.htm</a>

So for a gradual turn you can sort of do what feels natural, but for a quick enough turn you need special practice. That might match up with motorcycle instruction practice fairly well if we expect that motorcycle turns are more likely to need to be fast enough to need the rider to perform a counterintuitive movement.
