Motorcycle cornering safety: how to ride curves and avoid running wide
How to set your speed, look through the turn and recover if you start running wide
Picture a rider on a sunny two lane road. A right hand bend tightens more than it first looked. The bike drifts toward the centerline. The rider’s eyes lock onto the oncoming lane.
The Motorcycle Safety Foundation (MSF) calls running wide in a curve a primary cause of single vehicle crashes [4]. In 2024, 6,228 motorcyclists died on U.S. roads, the National Highway Traffic Safety Administration (NHTSA) reports [1]. The Insurance Institute for Highway Safety (IIHS) found that 35% died in single vehicle crashes [2].
This guide explains cornering the way advanced rider coaches teach it, with a routine, a line table and drills that add to, but never replace, hands on training.
Why curves catch riders
Curves are hard on every vehicle: the Federal Highway Administration (FHWA) links more than 25% of fatal crashes to them [6]. For riders, the risk is sharper.
- Curves are common in rider deaths. In Ohio from 2004 to 2008, about 38% of motorcyclist deaths happened at or near curves, versus 29% of fatal car crashes. In Florida from 2005 to 2015, 57% of fatal single motorcycle crashes happened on curves [7].
- Running wide tops the list. The National Transportation Safety Board (NTSB) studied 177 crashes from a federal study in Orange County, California. Loss of control played a role in 60. Running wide in a curve was the most common pattern (21), ahead of slide outs from poor braking (17) [3].
- Lone crashes are deadlier. In that sample, single vehicle crashes were 19% of all crashes but 50% of fatal ones [3].
- Roadsides are unforgiving. In 2024, 24% of motorcycles in fatal crashes hit a fixed object, compared with 16% of passenger cars [1].
Speed and alcohol often set the stage: in 2024, 37% of riders in fatal crashes were speeding, more than drivers of any other vehicle type [8]. Among riders killed in single vehicle crashes, 40% were alcohol impaired, versus 18% in multivehicle crashes [1]. Curves are not just a country road problem, since 66% of motorcyclist deaths in 2024 happened in urban areas [1].
Slow, look, press, roll: the core sequence
MSF teaches cornering in four steps [4].
- Slow. Before the curve, close the throttle and use both brakes if needed, so you arrive at a speed you can hold all the way through [4].
- Look. Turn your head, not just your eyes, toward where you want to go. Keep your eyes level with the horizon [4].
- Press. Above walking pace, a motorcycle turns by leaning. To start the lean, press the grip on the side you want to go (press left, lean left, go left), which is called countersteering [4, 5].
- Roll. Once leaned, roll the throttle on gently to hold or slightly build speed, which steadies the bike [4].
Finishing each step before the next keeps you from asking the tires to slow and turn hard at once.
Entry speed: decide before you lean
Most curve trouble starts on the straight before it. Washington’s rider manual calls setting your entry speed before the corner the key to avoiding braking in it [5]. It bases that speed on how far you can see, how tight the curve is, the surface and the slope [5].
Riders who take curves too fast often cannot hold the turn and end up in another lane or off the road, Pennsylvania’s manual notes [9]. A yellow advisory sign helps, but it cannot warn you about gravel past the bend.
Look through the curve
A motorcycle tends to go where your eyes go. Staring at a hazard and drifting toward it is called target fixation. Washington’s manual tells riders to look where they want to go [5]. Turn your head toward the exit and move your gaze ahead as the curve opens. Only glance at hazards.
Choosing your line
Your line is the path you trace across your lane. MSF notes that the best path may not follow the road’s curve [4]. Its default, the center of the lane from entry to exit, shows oncoming traffic early and leaves room if a driver crowds the centerline [4].
Many instructors also teach an outside inside outside path, which widens your view and eases the curve [5, 9]. It can bring you closer to oncoming traffic and edge debris, Washington’s manual cautions [5]. That manual also describes a delayed apex: staying outside longer and turning in later, so you see farther for longer [5].
This table is our summary of common instruction, not a rule for every road.
Comparison compiled by Safety Behind the Wheel Foundation
| Curve ahead | Entry speed | Line | Watch for |
|---|---|---|---|
| Open curve, clear view, clean surface | Set before turn in | Center, or outside inside outside within your lane | Oncoming drivers cutting the curve |
| Blind curve | Slow enough to stop in the road you can see | Stay outside longer; turn in late | Stalled cars, animals, gravel past the bend |
| Tightening curve | Slower than the opening suggests | Late turn in, saving lean for the tight end | Running out of lane at the exit |
| Downhill curve | Lower, set earlier, lower gear | Center or late turn in | Speed creeping up |
| Off camber curve | Lower | Center, extra smooth inputs | Less grip in reserve |
| Gravel, leaves or wet paint | Lower | Cleanest path; upright over the patch | Edges and the inside of curves |
Lean, traction and smooth inputs
Think of tire grip as one budget that turning, braking and accelerating all draw from. MSF notes that any lean reduces the traction left for braking [4], because part of that grip is already being used to turn, as the NTSB explains [3].
A road design guideline cited by FHWA warns that losing front tire grip in a bend almost always ends in a crash [7]. FHWA adds that a sudden change in pavement grip can cause a fall even without braking [7], which is why smooth inputs matter:
Blind, tightening, downhill and off camber curves
Blind curves. If a hill or brush hides the exit, ride at a speed that lets you stop in the road you can see. Turning in later shows you more of the bend [5].
Tightening curves. Some curves get tighter as you go, MSF notes [4]. Engineers call them decreasing radius curves. If you enter at the speed the opening suggests, you will need more lean just as room runs out. So enter slower and turn in late.
Downhill curves. Gravity keeps adding speed and shifts weight to the front tire [5]. Slow earlier and choose a lower gear before the curve, since you may need the brakes to slow enough to downshift [4].
Off camber curves. An off camber curve or road crown tilts away from your turn, leaving less grip in reserve. So enter slower. Washington’s manual tells riders to factor a corner’s slope into lean and speed [5].
Gravel, leaves and other surface traps
MSF lists poor grip surfaces that include wet pavement, gravel, mud, leaves, painted lines, steel plates and utility covers [4]. Washington’s manual adds oil spots and drainage grates [5]. Dirt and gravel also collect along road edges, especially on curves and highway ramps, MSF warns [4]. A federal Motorcyclist Advisory Council has flagged heavy crack filler (often called tar snakes), chip seals and slick pavement markings as rider concerns [11].
Scan early, especially in fall and after storms. Adjust your line before the curve to miss a patch. If you can’t avoid it, cross as upright as you can with no sudden changes. Keep off the brakes on very slick spots [4, 5]. See our guide to riding in weather, darkness and poor road surfaces.
Braking before and in a curve
The best curve braking happens before the curve [5]. But a stalled car or an animal can force you to slow in the middle of a curve. MSF’s guidance is to straighten the bike first, then brake hard, when road and traffic allow [4]. If you can’t, brake smoothly and more gently than you would upright, then squeeze harder as you slow and the bike stands up [4].
MSF’s riding tips confirm you can use both brakes while leaned if you apply them gradually and with less force [10]. Grabbing them can cause a slide out, the second most common loss of control pattern in the NTSB study [3]. Some advanced courses teach carrying light brake pressure into a turn, a precision skill best learned from a coach on a closed course.
Some newer bikes offer cornering ABS or stability control that accounts for lean angle. The NTSB says wider availability could improve safety [3]. They help, but they cannot create grip. See our guides to motorcycle ABS and traction control and emergency braking and swerving.
Roadside hazards beyond the edge
When a rider leaves the road in a curve, the trees, poles, ditches or barriers beyond the edge often decide how badly they are hurt.
Guardrail is hard on riders. An FHWA research review cites a finding that riders made up 40% of guardrail related deaths in 2017, though motorcycles were about 3% of registered vehicles [12]. A sliding rider can strike the posts under the rail [12]. After Utah added a lower rail at one site, it saw no motorcycle crashes there for three years, a promising but small result [11].
Read the outside edge of every curve. Slow down more where there is little room to recover. Report gravel or broken pavement to your state or county road agency.
If you run wide: what to do
Practice drills for a safe area
Practice in a clean, empty lot with permission, in full gear. Keep speeds under about 20 mph. MSF’s free drill videos include turns, stops in a curve and a curves challenge [13].
- Head turn circles: ride a large circle with your head turned to look across it, then switch directions.
- Brake, then turn: set one cone where braking must end and another at your turn in point, then move the second cone later to practice a delayed apex.
- Tighten the arc: in a gentle curve, add a little inside grip pressure to rehearse the run wide fix.
- Stop in a curve: at low speed, straighten and then brake to a stop. Later, add light braking while leaned.
Then get coaching: MSF’s one day Advanced RiderCourse focuses on braking and cornering skill, hazard awareness and personal risk assessment [14]. If you are new, returning or carrying a passenger, leave extra margin in every curve.
Frequently asked questions
What does “slow, look, press, roll” mean?
It is MSF’s four step cornering sequence: slow before the curve, look through it, press the inside grip, then roll the throttle on gently [4].
Is it OK to brake in a curve on a motorcycle?
Yes, but gently, because leaning reduces the grip available for braking. Straighten first if you can, or brake smoothly and add pressure as the bike stands up [4].
What should I do if I enter a curve too fast?
Keep looking at the exit, press harder on the inside grip and lean more [5]. Stay smooth on the throttle and avoid grabbing the brakes.
The bottom line
Recommendation from Safety Behind the Wheel Foundation
Set your speed before the curve and turn your head to look through it. Keep every input smooth. If you start running wide, look to the exit and press harder on the inside grip. Then practice, and take an advanced course.
