seriously I have to confess...
In last two weeks I have found some very interesting facts..
Derbi was agile enough to swing and boom in traffic due to its small our all build and less khalara and very good power... but it was a no go for a daily runner becuase it might have ended non repaired and no spare part at all.
Ravi Storm is still good bike but after checking derbi I feel (also GS) that they both lack agility "the rider control over ride" largely I doubt its due to the wheel base and bulky design but may be there are more ingredients which make the over all experience good enough.
where as the curse of CG is that brutle that even you throw it from a 20story it will still survive becuase its after sales and mechnic network is so strong that it cannot die in any case.
but its riding experience is very bad not recomended for long route at all.
