my mum rides bikes and i have seen people do wheelie on youtube and i have been on as passenger and i have rode dirt bikes a few times and some pocket rocket on a track when i was a kid
Is it possible for aerodynamics to effect a motorcycle in such a way as
to become increasingly unstable as the bike picks up speed beyond about
70kmph? --> yes
Also, can wind gusts on a bridge become strong enough to significantly
effect a motorcycle at high speeds? I've had wind gusts push me a foot
or two to the left, but nothing too significant. But I was only doing
like 70kmph, so I'm wondering if this could become much more dangerous
at greater speeds. -----> probably not unless it's from behind maybe less than 1kmph
most accidents are caused by people in cars who don't pay attention to the people on bikes.. that's what i have seen my mum complaining about a lot and other things to make awareness to people in cars to look where they're driving
