[7] On his final appearance of the season the gelding was stepped up in class to contest the Group 3 Lion Rock Trophy on 29 May and started favourite ahead of Helene Paragon (Hong Kong Stewards' Cup).
[9] Rapper Dragon was scheduled to begin his four-year-old campaign in the Sha Tin Trophy on 23 October but was withdrawn from the race after sustaining an injury to his right hind leg.
In the Hong Kong Classic Mile for four-year-olds on 22 January 2017 he started the 1.1/1 favourite against thirteen opponents headed by Pakistan Star, Beauty Generation and Eagle Way (Queensland Derby).
[11] Four weeks later the gelding moved up to 1800 metres for the Hong Kong Classic Cup and was made the odds-on favourite in a fourteen-runner field which included Seasons Bloom, Pakistan Star, Beauty Generation and Eagle Way.
In a race run in heavy rain, Rapper Dragon was among the leaders from the start, accelerated into the lead in the straight and came home one and three quarter lengths clear of Pakistan Star.
[13] After the race Moore said "This is a really classy animal, he's done everything right, he progressed through the classes, today was the grand final and we won it... there was a moment or two there when he probably was in a tight position but he extricated himself and hit the line like he usually does – really, really strongly.
Starting the 0.6/1 favourite he raced in second place behind Contentment before taking the lead in the straight and held off the strong late challenge of Beauty Only to win by half a length.
