think just rem to take loh,i used to forget to take also then kana taken by others...or maybe you wanna buy a small lock to lock it up,but anyway this also attracts ppl to break your lock so the best way is to just remind yourself,make it a habit
Whereas for 2a or class2 bike,totally depends on you,actualli class 2a is quite enough in sg liao,but class2 lokks n performs better lah
but however its maintenance is much much higher than 2a bikes...maybe get class 2 but get 600ccs bike loh,now i riding 900cc one but feel that actualli 600 or 750cc is enough liao,sg seldom open more than 200km/h one...and maintenance not tat high also
