A scooter windscreen pushes the airflow up and around the rider, but it is not always worth having, especially on the 110–125cc scooters and semi-automatics most travellers rent in Vietnam. This guide weighs the pros and cons using Motorcycle.com’s screen-buying guide, hands-on screen testing by webBikeWorld, an SAE wind-tunnel study and care instructions from screen maker National Cycle.
Quick answer
Table of contents12
- Worth it for long days in cold weather or drizzle: a screen keeps wind and rain off your chest and reduces fatigue.
- Not needed if you mostly ride around town in the hot season: a tall screen cuts cooling airflow.
- Height is everything: too short and your helmet gets buffeted; too tall and you look through plastic that gets dirty, wet and glary.
- On a rental: choose a model with a factory screen rather than adding one.
- Never use household glass cleaner: alcohol and ammonia damage plastic screens.
What a screen does and doesn’t do
According to Motorcycle.com, the core job of a well-designed windscreen is to deflect wind above and around the rider, while also shielding you from rain, debris and bugs and reducing fatigue. It does not replace rain gear and does not cover your hands or legs; in heavy rain you still need proper waterproofs.
| Situation | Where a screen helps | What to watch |
|---|---|---|
| Long rides at steady speed | Less wind pressure on your chest, less fatigue | Get the height right to avoid helmet buffeting |
| Winter and drizzle | Keeps some rain and cold air off your upper body | A wet screen hurts visibility if you look through it |
| Summer city riding | Little benefit | A tall screen reduces cooling airflow |
| Dusty or dirt roads | Blocks dust and small stones | Motorcycle.com suggests a look-over height so mud does not block your view |
Low vs tall screens with an open-face helmet
Motorcycle.com describes two approaches. A look-over screen should sit roughly between your nose and eyes when seated, leaving your view unobstructed. A look-through screen should stop about 2–3 inches (5–7.5 cm) above your helmet: maximum protection, but less airflow in the heat, possible glare and a screen you must keep clean. The screen should also be at least as wide as your shoulders.
If your helmet is constantly bobbing in the airflow, Motorcycle.com says the screen is probably too short. Mark Hinchliffe of webBikeWorld explains that buffeting comes from the back pressure behind the screen. Open-face helmets, common in Vietnam, leave your face more exposed to wind and noise, so see our guides to helmet visor types and motorcycle earplugs.
Rain spray and looking through a wet screen
Hinchliffe says his screen keeps his chest dry in winter, and in rain he can still see over its top edge. That is why many riders prefer a look-over height: when the screen is wet, dirty or lit up by oncoming headlights at night, you are not peering through the plastic. If your screen sits at eye level, keep it spotless and slow down in heavy rain.

Crosswinds and stability on small bikes
Many riders worry that a tall screen makes a small bike more vulnerable to crosswinds on mountain passes. The evidence is not clear-cut: a wind-tunnel study by Kevin R. Cooper (SAE, 1983) on handlebar-mounted fairings and windshields suggested they can help stabilise front-end wobble and may reduce crosswind response, although the author noted the yawing moments were hard to interpret without a dynamic simulation.
What is clearer is that an add-on screen has to be solidly mounted: Hinchliffe found a heavy clip-on visor could make his screen wobble and vibrate, especially at low revs and over bumps. On windy passes, screen or no screen, slow down, keep a relaxed grip on the bars and leave more space around other vehicles.
Pick a rental model with a screen instead of adding one
A factory screen is designed for that model and comes with proper mounts. On a rental, do not drill, clamp or swap screens yourself: it alters someone else’s bike, and you cannot easily tell whether an add-on screen is mounted securely. If you want a screen for a long trip, ask in advance which models already have one.
If you are still choosing a bike, read whether an automatic scooter suits your travel plans; if you will mostly ride in the city, see riding in Hanoi’s Old Quarter. Want a windscreen for the mountain loops? Ask Mr Tú – Old Quarter Motorbike Rental which models come with one before you book.
Cleaning and caring for a screen
Motorcycle screens are usually acrylic or polycarbonate. Motorcycle.com notes acrylic is often cheaper, scratches can often be buffed out and it yellows less in UV light, while polycarbonate is tougher and shatterproof but can discolour after long sun exposure.
- Do not use household glass cleaners: National Cycle warns that alcohol or ammonia solvents will destroy the plastic.
- Keep brake fluid, alcohol, ammonia, strong solvents and alcohol-based rain repellents off the screen.
- Spray a dedicated plastic-screen cleaner one section at a time, wipe with a folded microfibre cloth in circular motions, then re-fold and wipe dry.
- Do not cover the bike with cheap vinyl sheets, whose chemicals can damage the plastic.
Frequently asked questions
Is a scooter windscreen worth it for touring?
It helps if you ride for hours in cold weather or drizzle, and matters less if you mostly ride around town in the heat. On a rental, choose a model with a factory screen rather than fitting one yourself.
Is a tall or a short windscreen better?
Motorcycle.com says a short screen (top edge between nose and eyes) gives a clear view, while one 2–3 inches above your helmet gives maximum protection but is hotter and must be kept clean. Constant helmet buffeting usually means the screen is too short.
Does a windscreen make a scooter unstable in crosswinds?
There is no clear evidence that it does. A 1983 SAE study suggested handlebar-mounted screens may reduce crosswind response, but a poorly mounted add-on screen can vibrate. In strong wind, slow down and keep a relaxed grip.
How should I clean a motorcycle windscreen?
Use a cleaner made for plastic screens and a microfibre cloth, wiping in circles. Avoid household glass cleaner, alcohol, ammonia and brake fluid.
