they didnt put discs due to price..because in that case they have to ask 10k more which they cant market that well in PK..see the low sale of honda 125 delux 2010 model...
actaully suzuki opted for an OHC engiine..which is costly as compared to an OHV engine.. RAVI provided discs instead of a reliable engine..
@umer009..yaar y i like Suzuki engine is because when u r on constant 100km/h u r at 7800 rpm in n 5th gear..tell me any other bike in PAK which remains so cool at 100km/h..and at 7800rpm..u can constantly go to Islamabad without engine breakup..thats y people use gs150 for long journeys..
PAK main its the only quality engine..rite now..
