KMB MCW Metrobus 2-axle ( M ) During 1983 to 1985, the Kowloon Motor Bus acquired totally 80 MCW Metrobus 2-axle buses which is modeled as DR102. KMB later fleeted them as M1 - M80. In that period, the passenger capacity allowance was changing from batch to batch. The difference between them is just on the standees. They are all originally installed with Gardner 6LXB engine and Voith DIWA-851 fully automatic gearbox. However, there are three Metrobus, the M58 - M60, are specially fitted with Cummins LT10 engine with maximum power output of 245bhp. As the M58 - M60 had a good performance, later in the last batch of the Metrobus 2-axle, KMB introduced 8 Metrobus with fleet number M81 - M88. These buses fitted with Cummins LT10A engine with can perform 280bhp horse power. The transmission also changed to Voith DIWA 864.4G fully automatic gearbox. These buses were then put into the services of route TWISK.
