I have been riding this bike for the past 2 years and thus I shall base my review upon my experiences with this bike.
firstly coming to the request, the mileage is indeed 40 to 45 kpl and even at times 50 kpl. It is a very nice and powerful bike its pickup is quite good and u get max torque between 5ooo to 6000 rpm. the pickup when the bike is in the 4th gear and at speeds of say 50 kph or so then the pickup is quite sad , however with clever manipulation of throttle and gears you can get quite a good pick up, ofcourse at the expense of your fuel economy.
the bike however is not very stable that of course also means that it is highly manoeuverable.i would recommend it for those whove got some experience riding a bike.but if anyone wants a great bike then hey better go for the hero honda cbz , its a great bike. I have ridden it and I say folks there is nothing like it. I shall write about the cbz some other time though.ciao.
ps: the seat ends up causing a lot of discomfort to the pillion especially during long drives.its a pain in the proverbial a**.
