The ALX500 was fitted to Dennis Trident 3 and Volvo Super Olympian chassis (they could be distinguished by the design of the engine compartment: with round indicators for Dennis and square indicators for Volvo), and came in lengths of 10.6, 11.3 and 12 meters (35, 37 and 40 foot). The ALX500-bodied buses were sold new to Citybus, Kowloon Motor Bus, Long Win Bus, New World First Bus and Kowloon-Canton Railway Corporation in Hong Kong. Due to the climate there, all of them were fitted with air conditioning systems, and as a result lacked a rear window on the lower deck. The extra length of the buses meant the seating capacities were near the 100 mark for the 12.0 metre variant.
