On paper, the Chang International Circuit at Buriram is a very simple proposition.
A tight corner followed by a short straight, then a tight corner followed by a very long straight, and then a long hairpin followed by a medium-length straight. And then a bunch of complicated twists and turns to get back to the start and finish line.
Of course, a track is never the same on paper as it is when motorcycles actually race on it. Sure, Buriram has three straights which determine a lot of the circuit’s character.
But there is much more to it than just getting the bike turned and getting on the gas as quickly as possible. There are a plenty of places with a choice of lines, where a canny rider can find an opening on the rider ahead. And the nature of that tighter interior sector is such that a bike which isn’t a basic drag bike can make up a lot of ground.
Take Turn 3 (the long back straight has a kink formally designated as Turn 2), the long hairpin at the end of the straight. Not perfectly flat, it offers a choice of two lines: stay inside and hug the inside kerb, and try to make the ground up on corner exit; or run in wide and cut back to the second apex carrying more speed. Both lines work.
Both lines get you to the corner exit at roughly the same point in time. And both suit two very different bike characters. It may look point and shoot, but it really isn’t.
