Hi Muhammad Farhan Sulaiman, thank you for your question. You can not register your motorcycle to a Singapore plate number. However, you can drive Malaysia-registered cars or motorcycles into and out of Singapore if you meet these requirements:

-Have a valid Autopass Card and LTA’s approval email. Plan for at least 2 weeks ahead to allow approval for your VEP/Autopass card applications

-Have a valid road tax for the vehicle

-Have a valid certificate of insurance (with third party coverage) to use the vehicle on Singapore roads

-Settle all outstanding fines for your vehicle. (You can check online at AXS website for outstanding offences)

You are not allowed to keep or use a foreign vehicle in Singapore if you are a:

-Singapore Citizen

-Singapore Permanent Resident (PR)

-Resident of Singapore

-Long-Term Visit Pass or Dependant's Pass holder

-Student's Pass holder

-Training Employment Pass or Work Holiday Pass holder

-Work Pass holder who is also a resident of Singapore

Any person who is not a resident of Singapore, but holds a Work Pass issued by the Ministry of Manpower, may drive a foreign-registered vehicle in Singapore if ALL these conditions are met:

-The person is the registered owner of the vehicle

-The person resides outside Singapore

-The person has a valid certificate of insurance (with third party coverage) and road tax to use the vehicle on Singapore roads

-The vehicle is kept or used outside Singapore for a total period of 6 hours or more every day

-The vehicle has an Autopass Card to validate its entry / exit at Woodlands or Tuas Checkpoint and to pay for the required fees and charges
