you can get a SUZUKI GSXR 600 SRAD 1997. I sold mine a year ago and i hear it is for sale for 500k in a local showroom on college road. I guess name of the showroom is RPM. When i sold it, it was in excellent condition. Genuine color, engine and wiring.
You can get NCP 2004-2006 model YAMAHA R6 or HONDA CBR 600 RR in this budget. If interested, i know someone in Islamabad with clean bikes.
