It seems only logical that riding techniques would change as much as the bike technology has, but is that true? The evolution in tire technology has been huge. But is traction so good now that riders can ignore its limits? Has the increase in traction for braking, cornering or acceleration eliminated those limits, such as lean angle, that govern them? Have racing lines changed substantially over the past 15 or even 30 years? Does having higher corner entry, middle and exit speeds from better tires make it easier to find the right lines? Were riders able to run precision lines on the old bike/tire combinations?
