The bus - after successful trials with the four prototype Dennis Jubilants (N1-4) Kowloon Motor Bus placed an order for 50 chassis, which were delivered in 1979/80. Orders for a further 310 chassis followed over the following years.

Of the first order, 49 were fitted with Alexander bus bodies, which had been built in Scotland. The remaining chassis received a similar body, built in Hong Kong, but was classified as a coach, having 2+2 coach seats (as opposed to 3+2 for the buses) and was also fitted with air-conditioning. It received no fleet number, being known only as CF4180 and entered service almost 4 months after the last bus in the batch (on 11th June 1980). With the curtailment of coach route 206, CF4180 became redundant and was withdrawn, pending removal of the air-conditioning and fitting of bus seats, after which it entered service again as N364 introduction.
