feeufee,
From my personal experience ,what I've gone thru is that the plus ronda guys (malaysian version of EMAS), were unable to tow bikes but luckily for us, they have contacts for normal lorry services. They charge ard 300-450 ringgits, if u want to get ur bike to gelang patah esso.( tat's from perak, may differ for different location )
The other cheaper alternative is to get it towed to any railway station but KTM provide cargo service pick-up points only in 3 places through-out Peninsula Malaysia. ( u might wanna check this info again. ) The whole procedure cost us less than 150 ringgits.( bike tow plus train cargo charges )
Ride safe!
