avoid china bike if you are not willing to spend times pushing the bike into workshop and like to take the bus while waiting for your bike to be repaired....

there are reasons why it's soo cheap yet you don't see many of them on the road - most who bought them are left in the workshop
so far, the only few china bikes that does it well is the Demak DTM - ask likimikukukukukukuu

if you are shy or don't have free time to visit any bike shop, just go to mudah.my and see the listings there
you can get the indicative pricing for brand new and used bikes there
a used ninja250 (current gen one) is about 15-17k while a used blade 250 is from 9k for earlier carb models
brand new ninja is about 21k and blade is about 17k. so u save a lot if u go the 2nd hand route.
correct me if i'm wrong on the prices
