Hi there! I have zero riding experience. I attended couple of B Full classes in driving school, now only riding a clutch kapchai for practice in driving school since I have no bikes at home to practice. Currently I decided to get myself a SECOND HAND scrambler/mortard for practice and commuting.  I'm 5'5 (165cm) tall, but I believe the height problem is not an issue if I ride with riding boots. Budget is within range of RM4k-5k. At most is RM6K.

Current options I have in mind were:-
Demak DTM 150/200
KLX 150 s/l
Honda MTX 200
Honda CRF250L

Would like to know your thoughts on the list of options above. Other suggestions are most welcomed as well.

[update]
Okay bro. After some time of consideration, I have decided to go over my budget for a bit and buy the Kawasaski Z250sl which is a little bit more expensive than the second hand Kawasaki KLX150. I find it a realistic option as I find its riding position similar to the ER6N that is available in the driving school just that the cc is smaller. Do you think getting a Kawasaki Z250sl is a realistic approach for me to practice riding and to commute? In fact even if I passed my B full license test I will still be riding with this bike for another few years before I upgrade to a new bike with larger cc.
