In motorsport, the racing line or simply "the line" is the optimal path around a race course. In most cases, the line makes use of the entire width of the track to lengthen the radius of a turn: entering at the outside edge, touching the "apex"—a point on the inside edge—then exiting the turn by returning outside.
How Late Apexing Will Make You Faster and Safer on the Street and Track. Learn how to apex early and late to find the fastest, safest line around a corner for street, track, or rally driving.
This line is known as the squaring off, or late apex line. Along with why turning in later is beneficial, I’ll also briefly cover a very typical trait that a lot of riders adopt; turning in too early. Late Apex Line / Squaring Off. As the above heading would suggest, the late apex and squaring off line is exactly that.
Leave it too late and you’ll miss the apex, too soon and you’ll have to tighten your line mid-corner. Get this right and you’ll have set yourself up for a good line. Remember that the apex may be further round the turn than you can see, so make sure you learn the track and the clipping points before driving in anger.
For example, if I had not driven the super late apex line on purpose and I instead had just severely missed my braking point, the super late apex line would no longer be a bad strategy, it would then be correct. The instant I realized that I went too deep, I would need to create a new optimal line for the false apex I had just accidentally created.
The problem with very late turn-ins is it makes a driver need to turn more aggressively right away. It essentially makes a corner tighter than it needs to be. If you take a look at our whiteboard example below, you will see the late turn in of the red line, and the earlier turn in of the green line have the same apex point.
How to drive the perfect racing line is a fundamental driving theory we need to master before we can be fast on circuit. From the braking point, through turn-in, apex (clipping point) and exit, the racing line is critical to lap time.
A quick look at lines and apexes as used in racing and on the street.
Home › All Things Motorcycle › 4 Reasons Why You Need to Use Cornering Lines. ... Apexing early requires a late increase in lean angle. Delayed Apex Line. ... To execute the delayed apex line requires a quick turn-in using firm countersteering. The harder you press on the inside handgrip, the quicker you will turn.
Depending on the line you drive through the corner – and dictated mostly by where and when you turn in to the corner – your apex can be early in the turn, in the middle of it, or late. Any apex past the geometric middle of the corner is considered a late apex. As you can imagine, there are varying degrees of lateness, too.
