i am riding a KRR. the power and weight is managable for a 2B
bike.
i would advise you to get a bike without fairings (maybe a phantom
or scrambler). insurance excexss is cheaper too.
damaged fairings cost a bomb to replace and if you are a beginner
you will be likely to drop the bike. as for the pick up thing, it
does not differ very much for 2B bikes. do not make that your major
criteria when choosing a bike.
only when you get to the 2A class will there be a noticeable
difference in power.
for second hand bikes, its best to go with someone who knows about
bikes. i believe that people in this forum will be glad to
accompany you if you want to buy from a shop.
as with all second hand things, its basically a hit and run affair.
things will spoil more often. try to set aside some money for
repairs as well if buying second hand.
