The chief reason that had contributed to the design-related criticisms of the segregated motorcycle lanes on expressways is the adoption of the design standards of segregated bicycle lanes, namely the standards defined by "Arahan Teknik (Jalan) 10/86: A Guide to the Design of Cycle Track" by Malaysian Public Works Department. According to "Arahan Teknik (Jalan) 10/86: A Guide to the Design of Cycle Track", the typical design speed limit being applied on cycle tracks is as low as 60 km/h. However, the design speed limit is too low, as the reported 85th percentile operating speeds of motorcyclists along the motorcycle lanes at the Federal Highway during peak hours and non-peak hours are 72 km/h and 80 km/h respectively.
