nothing more important than the safety of rider. Piaggio/AHL have my respect for offering diskbrakes on their flagship bikes.
It would roughly cost suzuki around 5000 PKR to include disk in the package.
but when we do it by ourself, cost goes upto 15K because of parts replacement.
So it's pretty bad that it isn't included.
Even look at Intruder M800. Only single disc at front and drum brakes at rear :-!
I bet Intruder owner won't be very happy with brakes either.
