Hong Kong's Cheung Wai-on stopped his bike at a corner, beat his chest and poured his heart out in a tearful burst of emotion after surrendering his ACMC Trophy title yesterday. The 20-year-old Cheung had to be consoled by a race marshall moments after crossing the finish line in fourth place behind the man he feared most - top Japanese rider Naoki Kato, who rode his Honda RS125 to victory. In complete contrast to last year's race when he threw his helmet to an adoring crowd in winning his third straight ACMC Trophy, Cheung was reduced to anguish. He was no longer the best amateur rider in Macau and the thought of losing was unbearable. Cheung desperately wanted a fourth title but this time the Japanese visitors were too strong and Hong Kong's most talented rider said his best was not good enough. Ryosuke Nakaki and Akira Komuro finished second and third to complete a clean sweep for the Japanese raiders. Cheung finished 3.549 seconds behind Kato, but the Hong Kong rider clipped more than six seconds off his old lap record of 2:49.361. In fact, the top five riders home all improved on Cheung's lap record. But it was a day that will be remembered not for Kato's win, but for Cheung's tearful loss as his Honda proved no match for his rivals. 'I gave 110 per cent. I did my best, but I lost the race on the straights. We knew the quality of the opposition,' he said. 'I think I might have let my team down. I really never thought about second or third place. I wanted to win from the word go. 'We brought a Japanese mechanic to Macau, and we all did our best, but we lost to superior machines. I tried my best, I really did. But I couldn't compete with them. If I had their bikes, maybe it would have been a different story.' The story was signed, sealed and delivered by the sixth lap when Kato made his move by slipping past then-leader Cheung's Honda RS125 going into the main straight. Kato stayed in front of a chasing pack and despite Cheung's game efforts to close in on the leader, it was futile against far more superior machines. Kato clocked 33 minutes, 13.839 seconds for the 12-lap race. He finished ahead of Nakaki by 1.561 seconds, while Komuro was another 3.415 seconds behind - an agonising 0.134 seconds ahead of Cheung in the battle for third spot on the podium. 'My bike is made up of kit parts from the same factory as the Japanese riders,' said Cheung. 'But they were riding modified engines and that made all the difference. My bike cost 400,000 yen (about HK$28,000), theirs cost over a million yen.' Moments after the leaders crossed the finish line, Kato gave Cheung a consoling pat on the back, a thumbs up and a firm handshake. 'My compliments go to Wai-on, who did a good job. He's a good rider but our machine had an advantage. It was steady and powerful on the straights,' said Kato who was only invited to the race after organisers upgraded the event to include professionals for the first time. 'I waited for my chance and took it, but I had to be careful. I had to fight the urge to overtake Cheung earlier on. I was under team orders to bide my time. I took no risks during the race,' said the Japanese ace.
