Motorcycle registration plates in Kenya differ from those of ordinary vehicles due to specific legal requirements outlined by the National Transport and Safety Authority (NTSA).

• Motorcycle registration numbers begin with 'KM' (Kenya Motorcycle), distinguishing them from other vehicle types.
• The Traffic (Registration Plates) Rules, 2016 mandate separate specifications for motorcycle plates, including dimensions and the requirement for a single rear plate.
• Different vehicle categories, such as trailers ('Z') and tractors ('KTC'), also have distinct registration prefixes and designs.
