Motorbikes are not just transport in Thailand -- they are freedom. While Bangkok has the BTS, MRT, and thousands of taxis, most of the country runs on two wheels. In cities like Chiang Mai, a motorbike is not optional; it is essential for getting to coworking spaces, markets, waterfalls, and weekend trips. If you are staying more than a few months, buying your own bike makes financial and practical sense. Rental costs add up fast at 3,000-8,000 THB per month, and rental bikes are often poorly maintained. This guide covers every aspect of buying, registering, insuring, and riding a motorbike in Thailand as a foreigner.
Types of Motorbikes and Prices
The Thai motorbike market is dominated by Honda, Yamaha, and to a lesser extent Suzuki and Kawasaki. Here are the main categories with 2026 pricing.
**Automatic Scooters (110-160cc)** are what most expats ride. The Honda Click 160 is the most popular bike in Thailand and costs 55,000-60,000 THB new. It gets 45-50 km per liter, has under-seat storage for a helmet and groceries, and handles city streets effortlessly. The Yamaha Aerox 155 is a sportier alternative at 62,000-68,000 THB with better suspension and larger wheels. The Honda Click 125i is the budget option at 45,000-50,000 THB, essentially the same bike with a slightly smaller engine. For premium scooters, the Honda PCX 160 runs 75,000-85,000 THB with more storage, better brakes, and LED lighting.
**Premium and Maxi Scooters (150-300cc)** are for riders wanting more power and comfort. The Honda Forza 300 costs 175,000-195,000 THB and is popular with commuters wanting highway capability plus storage. The Yamaha XMAX 300 sits in a similar range at 170,000-185,000 THB. These bikes handle expressway riding comfortably and have enough storage for a full-face helmet and a grocery run.
**Manual and Semi-Automatic (110-150cc)** are workhorse bikes common among Thai riders. The Honda Wave 110i at 42,000-48,000 THB is the cheapest new option with a reliable 110cc engine and semi-automatic clutch. The Honda MSX125 (Grom) at 68,000-75,000 THB is popular among younger riders for its fun factor and customizable design.
**Mid-Size Motorcycles (250-500cc)** for riders wanting genuine touring capability. The Honda CBR250RR costs 168,000-180,000 THB, the Kawasaki Z400 is around 210,000 THB, and the Honda CB500X runs 285,000 THB. These are overkill for city riding but excellent for weekend trips through northern Thailand.
**Used Market** offers significant savings. A two-year-old Honda Click in good condition runs 30,000-40,000 THB. A used PCX 160 from 2021-2022 costs 50,000-65,000 THB. Facebook Marketplace, Kaidee, and the motorbike sections near university areas in every city are the main buying channels. Always check the green book matches the frame number and engine number.
The Green Book (Bai Pratuan)
The green book is the vehicle registration document and the single most important piece of paper for any motorbike in Thailand. It proves ownership and contains the bike registration number, frame number, engine number, owner details, and tax payment history. When buying a used bike, never hand over money without verifying the green book.
Check that the green book frame number and engine number match the numbers stamped on the bike. The frame number is usually on the steering head, and the engine number is on the engine block. Mismatched numbers mean the bike may be stolen or have illegal parts, and you will face serious problems transferring ownership or selling the bike later.
When you buy a used bike, both buyer and seller must go to the local Department of Land Transport office to transfer ownership. Bring your passport, the seller Thai ID card, the green book, and the signed transfer form. The transfer fee is around 100-300 THB and the process takes a few hours. Until the green book is in your name, you are not the legal owner.
For brand new bikes, the dealership handles registration and you receive the green book within 2-4 weeks.
Insurance
Every registered motorbike must have compulsory motor insurance (Por Ror Bor), which provides basic medical coverage for injury to third parties. This costs about 600-800 THB per year and is renewed annually at the Land Transport office or through insurance agents.
Compulsory insurance alone is not enough. It covers very little and excludes damage to your own bike or injuries to you as the rider. You need voluntary first-class insurance (Class 1) for comprehensive coverage including theft, fire, and at-fault accidents. Class 1 insurance for a Honda Click costs 3,000-5,000 THB per year depending on coverage level and deductible. For larger bikes, expect 5,000-12,000 THB per year.
Class 2+ (third-party plus fire and theft) is a middle ground at 1,500-3,000 THB per year for small bikes. This covers damage you cause to others plus theft and fire damage to your own bike but not at-fault collision damage.
Buy insurance from established companies like Viriyah, Muang Thai, or Tokio Marine. Avoid roadside insurance sellers who offer suspiciously cheap rates -- their claims process often requires you to pay upfront and wait months for reimbursement.
Driving License Requirements
Need help with Practical?

To legally ride a motorbike in Thailand, you need either a Thai driving license or an International Driving Permit (IDP) that covers Category A, used alongside your home country motorcycle license. However, the IDP is only valid for the duration of your tourist visa or visa exemption entry -- typically 60 days. If you are on a long-term visa, you are expected to obtain a Thai license.
The driving license process involves a medical certificate, residence certificate from immigration or your embassy, and passing both written and practical tests at the Department of Land Transport. The written test is available in English in Bangkok and Chiang Mai. The practical test involves a closed-course riding assessment through cones and a narrow bridge.
If you hold a valid motorcycle license from your home country, some offices allow you to skip the practical test and only take the written test plus a reaction test. Requirements vary by office, so check with your local DLT branch.
Riding without a valid license invalidates your insurance and can result in fines, bike impoundment, and serious legal problems in case of an accident.
Buying New vs Used
New bikes from authorized dealers come with a warranty (typically two years), proper registration, and zero mechanical uncertainty. Dealerships handle all paperwork including registration and first insurance. You pay more but avoid risk. Honda Big Wing, Yamaha shops, and independent dealers are found in every city.
Used bikes save 30-50 percent but require careful inspection. Check tire condition, brake pad thickness, chain and sprocket wear, fork seal leaks, electrical function, and ask for service records. Start the engine cold -- a warm engine can hide starting problems. Test ride if you can (requires a valid license). Take the bike to an independent mechanic for inspection before buying -- they charge 300-500 THB and can identify problems invisible to an untrained eye.
The biggest risk with used bikes is buying a stolen or encumbered vehicle. If the seller cannot produce the green book or wants to meet somewhere other than the Land Transport office for ownership transfer, walk away. Legitimate sellers have no reason to avoid the official transfer process.
Common Scams
Watch for rental shops offering to sell you a bike with monthly payments while keeping the green book. This is essentially a rental disguised as a purchase, and many foreigners lose their bikes and money when the shop reclaims them over minor payment delays.
Facebook Marketplace listings showing bikes well below market price are almost always scams. The seller will ask for a deposit before you see the bike, then disappear. Never pay before seeing the bike and verifying the green book in person.
Some used bike dealers tamper with odometers. A bike showing 15,000 km may actually have 80,000 km. Check for wear on grips, foot pegs, seat condition, and brake lever play -- these indicate real usage better than the odometer.
Safety Tips
Thailand has one of the highest road fatality rates in the world. Riding here requires defensive skills that go beyond basic competence. Always wear a helmet -- not just for safety but because it is legally required and police enforce it with 500 THB fines. A quality full-face helmet costs 2,000-5,000 THB and is the best investment you can make.
Never assume other drivers will follow traffic rules. Thai drivers routinely run red lights, make unexpected U-turns, and enter traffic without looking. Ride defensively, keep your distance, and always have an escape route planned.
Avoid riding at night in rural areas. Road lighting is poor, animals wander onto roads, and drunk driving increases significantly after dark. In cities, watch for open manholes, construction debris, and sand on corners during the dry season.
During the rainy season from June to October, roads flood quickly and become extremely slippery. Reduce speed, avoid painted road markings and metal grates, and consider taking a taxi on heavy rain days. The safety guide for expats covers broader personal safety topics.
Keep your bike in good condition with regular maintenance. Oil changes every 3,000-5,000 km cost 200-400 THB at any mechanic. Check tire pressure weekly and replace tires when tread depth falls below 1.5mm. Brake pads need replacing every 15,000-25,000 km depending on riding style. Regular maintenance prevents the mechanical failures that cause most single-bike accidents.
