First of all i am not a pro....
1 : few months ago i saw a CBR1000 with two brothers exhaust at the service station...i took some pic and had chat with the owner...i asked him price and he said he got it for 12 lacks (and from islamabad i think )....
2:there is a person i know who got Gsx-R 750 (old model) for 2 lack...(scrap but engine is gud and running condition) he said he was doing 200kmh+ in 5th gear ....so i suggest you to dont just look at 1 bike look out for more bikes....like R6 , gsxrs they will cost little low and will also fulfill the need for speed...
