Which scooter to rent on Koh Samui: 50cc, 125cc, 160cc or 300cc (2026)
Most people on Samui ride a 125cc automatic, and for most of the island that is the right choice. This page covers what each class of scooter does on the roads I ride: the ring road, steep climbs to viewpoints, and riding with two people.
Colour — all the routes on this site (list under the Routes button on the map), faint — every road I have ridden. GPX works in Maps.me, Organic Maps, OsmAnd, Garmin.
Which scooter for which road
| Class | Ring road and coast | Steep viewpoint roads | Two people |
|---|---|---|---|
| 50cc | I would choose a larger scooter | I would skip it | I would skip it |
| 110–125cc | My starting point for solo coastal riding | Assess the bike and your experience first | I would favour coastal trips |
| 150–160cc | An option to consider | Assess the bike and your experience first | My preferred class to consider |
| 300cc | For riders comfortable with its weight | I would want experience on steep roads | For experienced riders |
In my experience the engine size matters less than where you plan to go. The ring road route on this site is 63.7 km and rated easy. The mountain roads up to Pom Mountain and Secret Buddha Garden are a different matter. They include very steep sections, and that is where the scooter choice starts to count.
50cc: rare, and I would skip it
If you search for koh samui scooter rental 50cc, ask the shop whether it actually offers one before you count on it.
I would not look hard for one. A 50cc is slow to pull away from trucks on the 4169. The hills on the east coast bring it down to a crawl with a passenger. The steep viewpoint roads are simply out of reach. It does not save you any paperwork either, as the box further down explains.
If what you want is a lighter, easier scooter for a first ride, a 110cc automatic does that better. Try its weight and controls before choosing it. I wrote more about choosing and riding for the first time in renting as a beginner.
110–125cc: what most people should rent
This is what the shops actually have in quantity: rows of 110–125cc automatics, mostly the common Honda and Yamaha models. Don't hunt for a specific model. Ask for a scooter that is less than two years old and has good tyres.
- Solo. I would start with the easy ring-road, north-coast or south-west routes rather than assume it suits every climb. On the steep climbs, keep a steady throttle. On the way down, use both brakes and take your time.
- Two people. Fine on asphalt. On steep concrete the engine works hard going up and the brakes work harder coming down. I would not take a passenger up the mountain roads on a tired 125.
- Fuel. Ask about the tank capacity and fuel range of the particular bike, and plan fuel stops before setting out. The ring-road route on this site is 63.7 km.
150–160cc and 300cc: when bigger pays off
A 150–160cc scooter is the one I recommend for two people, and for anyone planning the mountain or viewpoint routes. Compare the particular bike's tyres, brakes and weight, and ask whether that version has ABS. Agree the rate and deposit before booking. I keep the current ranges on rental prices.
A 300cc maxi-scooter is a different kind of machine. It is much heavier than a 125 and stable and comfortable two-up on the ring road. It is also awkward to turn around on a narrow, steep concrete lane, and hard to hold if you stop mid-climb. Ask whether the shop offers one and what deposit it requires. I would only rent one if you already ride a big scooter at home. The upside is the bigger tank, which means fewer fuel stops.
License, and the five-minute check at the shop
Whatever you rent, check it before you ride off:
- Photograph every scratch with the shop owner watching.
- Squeeze both brakes hard and roll the scooter forward. It should stop dead.
- Look at the tyre tread. Bald tyres on wet concrete are how most falls I have seen start.
- Check the lights, the horn and the fuel level. In my experience scooters are often handed over nearly empty.
- Make sure the helmet fits and the strap closes.

Questions
Can I rent a 50cc scooter on Koh Samui?
Rarely. Most rental fleets start at 110cc, so ask the shop before you rely on finding one. A 110cc automatic is the practical alternative.
Is a 125cc scooter enough for Koh Samui?
I would consider a 125cc for solo coastal riding. For two people, I would favour a 150–160cc, but assess the actual bike and your experience before attempting steep mountain or viewpoint roads.
Which scooter to rent on Koh Samui for two people?
I would favour a 150–160cc automatic. Compare the particular bike's brakes, weight and condition, and do not choose a steep route on engine size alone.
Do I need a license for a 50cc scooter in Thailand?
Yes. Any scooter needs a motorcycle license (category A) — a foreign one only together with an IDP showing A, and you must wear a helmet. Rules and fines change, so check locally.
