So i'm seriously planning to buy this bike but few questions.. as this one is second hand and from 2011
is there any modifications what they have done between 2011-2013?

Second is as i live in Vietnam where they like to forger engine numbers and all ! how is engine number should look like in original?
This one it was all black and stamped as was frame number in "neck" of the bike but of course this one has red frame.

ou and yes. this one did not even have that plate in side of the frame on right side! that what made me think foul play :)
