Following the successful trial of SBS9C, Singapore Bus Services made the first major order of what would be a generation of Volvo buses for the 90s. Fitted with the Volvo THD101GC engine (9,600cc) and ZF 4HP 500 4-speed automatic transmission, these Volvo B10M-61 Mark II buses would serve alongside with the Scania N113CRB fleet.
First introduced in 1988, all 200 Mk II buses were delivered non air-conditioned, and fitting of bodywork was divided up equally between Walter Alexander and Duple Metsec. The door systems were supplied by Overton. For a couple of years these buses were assigned for cross-border service 170 to Johor Bahru. Half of these buses would eventually undergo refurbishment to be refitted with air-conditioning supplied by Denso, Sutrak, and Webasto, continuing service until they were displaced by the Mark IIIs.
Following two decades of loyal service, the last of these buses were finally retired in 2008 and replaced by Scania K230UBs.
