Gravel, dirt, sand and mud are part of most road trips into Vietnam’s mountain villages, through roadworks or after heavy rain. On a 110–125cc manual or scooter with road tyres, these are low-grip surfaces. This guide explains how to ride a motorcycle on gravel and other loose ground: body position, throttle and braking, choosing your line and when to turn back. It is based on the Ontario Ministry of Transportation motorcycle handbook (Canada), the NZTA motorcycle road code (New Zealand), a riding guide from Harley-Davidson Insurance and a tutorial from the German-language motorcycle magazine 1000PS.
Quick answer
Table of contents12
- Slow down before the rough section: traction on gravel roads is not as good as on pavement (Ontario) and braking distances are much longer (1000PS).
- Relax your arms and shoulders, let the bike move under you and keep your head up, looking well ahead (NZTA, Harley-Davidson Insurance).
- Keep the throttle steady: turn, brake, accelerate and change gears as little and as gradually as possible (NZTA).
- Brake early and gently while upright, without locking the front wheel (NZTA).
- Ride in the tyre tracks, away from the loose gravel at the edge of the road (Ontario).
- Deep mud or soft sand: on road tyres this is a real limit; consider another route or turning back.
Why are gravel, dirt, sand and mud harder to ride on?
The Ontario motorcycle handbook states that traction on gravel roads is not as good as on pavement. 1000PS (19/10/2024) adds that with less grip you cannot accelerate as much, especially when leaned over, and braking distances are clearly longer. On tyres, 1000PS notes that road tyres grip almost as well as off-road tyres on dry, firm sand and gravel tracks; once the ground turns soft, knobbly tyres start to make the difference. So on a road-tyred bike, dry and firm dirt roads are rideable if you go slowly and smoothly, while deep mud and soft sand are a real limit.
Body position and grip
- Relax: NZTA advises letting the motorcycle move under you rather than trying to control every movement.
- Hold the bars a little more loosely, arms and shoulders relaxed, and let the small wiggles of the surface pass through instead of fighting them (Harley-Davidson Insurance).
- Keep your feet on the pegs (Harley-Davidson Insurance); on a scooter, keep them planted on the floorboard. 1000PS recommends leaning your upper body slightly forward so you can steer freely.
- Over bumps: slow down, keep the bike as upright as possible, avoid turning and rise slightly on the footrests to absorb the shock with your knees and elbows (Ontario).
- Standing up is mainly needed in heavier terrain; easy gravel and dirt tracks can usually be ridden seated (1000PS).
- Look ahead: keep your head up and look where you want to go (NZTA), watching for holes and large rocks (Harley-Davidson Insurance).
Throttle, brakes and speed
| Control | What to do | Source |
|---|---|---|
| Speed | Ride slower, especially before curves | NZTA |
| Throttle | Slow down but keep a steady hand on the throttle; avoid sudden acceleration or braking | Harley-Davidson Insurance |
| Brakes | Brake earlier than normal, gently and upright; use the front brake carefully without locking the wheel | NZTA |
| Brakes on loose surfaces | Ease off the front brake and rely more on the rear | Harley-Davidson Insurance |
| Turning, gear changes | As little and as gradually as possible | NZTA |
| Following distance | Increase it and stay back from the dust cloud | NZTA |

Choosing your line: tyre tracks, road edges and ruts
- Tyre tracks: the Ontario handbook advises staying in the tyre tracks, away from the loose gravel at the edge of the road.
- Road edges: NZTA notes that dirt and gravel collect along the sides of the road, so stay away from the edge when making sharp turns at intersections and ride in the driest part of the lane.
- Ruts: according to 1000PS, if you can hold your planned line in a rut, it is a usable choice; plan your line earlier and more precisely.
- Roadworks: the Ontario handbook says to slow down because there could be ruts, mud or damaged pavement.
- Narrow or blind sections: because stopping distances are longer, 1000PS advises riding at a speed that lets you stop within half the distance you can see wherever oncoming traffic may appear.
Short sandy or muddy patches, and when to turn back
A short slippery patch you cannot avoid (per the Ontario handbook): slow down as much as possible before you get there and do not brake once on it. On a bike with a clutch, pull in the clutch and coast across; this removes engine drag from the rear wheel and helps avoid skidding. Stay off the brakes and, if necessary, use your foot to hold the motorcycle up.
Stop or change route when: you meet deep mud or soft sand beyond what road tyres can handle, the road is flooded (see riding a motorcycle through a flooded road), or a dirt road is getting heavy rain (see riding a motorcycle in the rain). On a rental, ask the owner before taking a route with dirt sections. If the bike goes down, read what to check after dropping a motorcycle before riding on.
Checklist before a dirt or gravel section
- Ask about road and weather conditions in advance.
- Slow down before the rough section, not once you are in it.
- Relax your grip, look far ahead and keep the throttle steady.
- Brake early, gently and upright.
- Ride in the tyre tracks, away from loose gravel at the edge.
- Turn back if you meet deep mud, soft sand or flooding.
Does your route include dirt roads? Ask Mr Tú – Old Quarter Motorbike Rental which bike suits it before you set off.
Frequently asked questions
Should I use the front brake on gravel?
NZTA advises braking early and gently while upright, without locking the front wheel; on loose surfaces, Harley-Davidson Insurance suggests easing off the front brake and relying more on the rear.
Do I need to stand up when riding on gravel or dirt?
According to 1000PS, standing is mainly needed in heavier terrain and easy gravel tracks can be ridden seated; the Ontario handbook advises rising slightly on the footrests over bumpy sections.
Can a scooter ride on sand and mud?
On dry, firm sand and gravel, road tyres grip almost as well as off-road tyres (1000PS); on soft ground such as deep mud or soft sand, knobbly tyres make the difference, so consider another route and ask the bike owner.
What should I do on a short patch of sand or mud?
According to the Ontario handbook: slow down before you reach it, do not brake on the slippery surface and, on a clutch bike, pull in the clutch and coast across.
