On a road you do not own, the fast line and the right line are not the same thing. A racing line takes the widest possible arc, clips the apex early and uses the whole track on exit. A road line deliberately gives up some of that, entering wider and turning in later, so that you can see further round the bend before you commit to a lean angle. The cost is a slower-looking corner. The return is that the bend can hide a tractor, gravel or a car across your lane, and you will still have somewhere to go.
The three positions that make up a line
Any line through a bend is described by three points, and riders who talk about "taking a good line" are really talking about where they put those three.
Entry position is where you are in your lane before you turn in. Moving away from the inside of the bend opens up your view around it. The Highway Code makes this explicit for left-hand traffic in rule 160, which tells drivers and riders to keep well to the left on right-hand bends to improve the view and reduce the risk of hitting oncoming traffic. Mirror it for right-hand traffic: on left-hand bends, sit to the right of your lane.
Turn-in point is where you press the bar and set the lean. Move it later and the arc gets tighter but the view gets longer, because you spent more of the approach looking through the corner rather than at the inside kerb.
Apex is the point where you are closest to the inside of the bend. On a track it sits near the geometric middle. On the road it sits later, often two-thirds of the way through, which is why the technique is usually called a delayed or late apex.
The exit follows from those three. A late apex points the bike towards the outside of your own lane on exit, with the bike already standing up, so you can start opening the throttle earlier and you are not drifting towards the centreline while still leaned over.
Reading the bend before you get to it
The tool that makes lines work is the limit point, also called the vanishing point — the furthest place where you can see the two edges of the road appear to meet. It is not a metaphor, it is a physical point you can watch, and it behaves in exactly two ways.
- The limit point is moving away from you at the same rate you are approaching it. The bend is holding its radius or opening. Your current speed and line are working.
- The limit point is coming towards you. The bend is tightening, or something is blocking the road. Speed comes off now, before the turn-in, while the bike is upright and the tyres are only being asked to do one job.
Riders who use it consistently stop being surprised by corners, which is most of the battle. Riders who do not use it read the corner from the first thing they can see — usually the inside kerb — and end up with an early apex, a tightening arc and no reserve. The pattern and its consequences are laid out in more detail in the guide to decreasing-radius corners.
| Line | Entry | Apex | What you gain | What it costs |
|---|---|---|---|---|
| Racing line | Full width of the surface, hard against the outside | Geometric middle, early | Largest radius, highest possible speed, least lean for a given pace | Uses the whole road, so on a two-way road it puts you in oncoming traffic; view round the bend is short |
| Late apex road line | Outside of your own lane only | Roughly two-thirds through | Long view before commitment, exit pointing into your own lane, room to tighten if the bend does | Tighter arc means more lean or less speed for the same corner; feels slow to riders who chase pace |
| Default lane position, no plan | Wherever the rider happens to be, often mid-lane | Wherever the bike ends up | Nothing, other than requiring no thought | Early apex by accident, running wide on exit, corrections mid-corner at lean |
Why the outside entry has limits
Positioning for view is a good default, not a rule to apply blindly, and there are several situations where the widest entry is the worst place to be.
Near the centreline on a right-hand bend in left-hand traffic, you are in the path of anything that cuts the corner — and lorries and buses routinely track over the line because their trailers cut inside. Sitting wide also puts you in the strip where oil, diesel and polished tar collect on many roads. On a bend with an adverse camber, the outside of your lane is the part tipping away from the turn, which reduces the effective grip exactly where you are asking for it. And on wet roads, painted lines and repair strips near the centre are among the most slippery things you can lean on.
The working compromise most experienced riders settle on is simple to say and takes years to do well: take the position that gives the best view, then give up as much of it as the surface, the traffic and the sight lines demand. Position is a variable, not a setting.
Building the line into a sequence
A single bend is easy. A road is a chain of bends, and the exit of one dictates the entry of the next. The rule that keeps a sequence tidy is that the line you choose has to leave you in the right place for what follows, which sometimes means deliberately taking a slower line through the first corner to be well positioned for the second. Riders who optimise each bend in isolation end up on the wrong side of the lane for the next one and spend the whole road catching up. There is a specific version of this problem on tight mountain roads, covered in the guide to riding a series of switchbacks.
Two constraints override any line you planned. Overtaking is one — the Highway Code's rule 166 says not to overtake where you cannot see far enough ahead to be sure it is safe, and specifically names approaching a corner or bend. The other is junctions and driveways hidden inside a bend, where the ideal line puts you where a driver pulling out will look last.
This is an explanation of how lines work, not a substitute for coaching. Line choice is one of the things that improves fastest with an observer on the road behind you, whether through a post-licence scheme such as the ones run by RoSPA Advanced Drivers and Riders or an equivalent in your country. An hour of assessed riding will find habits that no amount of reading will.
Practical checks that show whether your lines are working
Four signs, all of which you can notice while riding normally:
- You are adding lean mid-corner. Consistently having to press the bar again halfway round means you turned in early and apexed early.
- You finish corners near the centreline. A good road line finishes towards the outside of your lane, not on the paint.
- You are braking after turn-in. Occasionally that is deliberate, and it has its own technique, described in the explainer on trail braking. Doing it every corner means entry speed is being set by hope.
- Your eyes are on the road surface just ahead of the front wheel. Line comes from vision, and the fix is in the guide to where to look in a corner.
Grip underwrites all of it. A line that works on fresh tyres at correct pressure is a different line on a squared-off rear at 0.3 bar low, because the bike will resist tipping in and then fall through the turn once it passes the shoulder of the tread. Checking pressures cold before a ride is covered in the tyre pressure guide, and riders who want the reading on the bars use a sensor such as the JADO Bluetooth TPMS sensor rather than remembering to check at the pump.
Frequently asked questions
What is the correct line through a corner on the road?
Enter towards the outside of your own lane for the best view, turn in later than feels natural, apex about two-thirds of the way through and exit with the bike standing up inside your lane. Adjust for surface, traffic and anything that limits the view.
Why do advanced riders use a late apex?
Because it converts speed into information. Turning in later keeps the bike pointed further down the road for longer, so a bend that tightens or a hazard in the road appears while there is still time and lean angle in reserve.
Should I use the whole road if there is no traffic?
No. The road can only be seen as far as the limit point, and the vehicle you cannot see is the one that is a problem. Staying in your own lane also means a rider coming the other way with the same idea does not meet you head-on.
How do I stop running wide on corner exit?
Turn in later, so the bike is pointing across the corner rather than along it at the apex, and get your eyes to the exit earlier. Running wide is usually a vision and turn-in problem, not a lack of lean angle.
Does line choice matter as much on a slow road?
The speed matters less, the view matters just as much. Tight village and lane riding is where hidden junctions and blind entrances live, so the positioning that buys sight lines is arguably more valuable there than on a fast sweeper. Route planning helps here too, which is why some riders scout unfamiliar roads with a screen such as the JADO S6 riding system instead of guessing at junctions.
