If you are a short-term visitor: Yes, you can!

• If your licence is in English, you can legally ride in Singapore.
• If your licence is issued by a South-East Asia country (ASEAN: Thailand, Vietnam, Malaysia, Indonesia, Philippines, …), your driving licence is recognised in Singapore and other ASEAN member countries.
• If your licence is NOT in English, you will need to either get an International Driving Permit or an official English-translated of your licence by an embassy.

Please note that your foreign driving licence is only valid to use in Singapore with 2B class motorbike (under 200cc) for up to 12 months from the date of visa entry. After that, you will have to convert to a Singapore Driving Licence.
