Just did my 10k service at Guan Hoe past few days. They use special tools to open the belt protector cover. Their service more professional than a bike shop at Kallang. At Kallang, they dunno how to take out the cover just simply knock and cut the original cable tie(it can pull) without your permission. 1 of the crew said, "Boss we can't open it, something break or spoiled, we will not responsibility." When i heard, feel angry and i told them fix back everything and will go to Guan Hoe service.
COMMENT: PLEASE BEWARE WHEN SERVICE YOUR BURGMAN AT KALLANG.
