Very informative thread this one is.
Would like to add a line about a seemingly frivolous aspect of PDI which may ruin your happiness of new ownership within minutes if ignored.
Always ensure that all your details reflect correctly in RTA papers. Showrooms tend to make spelling mistakes and or drop/miss certain detail. This brings more troubles your way when you go from temporary to permanent registration when details mismatch with the supporting documents. Showrooms tend to wash their hands clean at such times saying the matter is between RTA and the the consumer.
Hence keep this as the last step of your bike PDI. Dont sign anywhere unless you ensure all details are one hundred percent accurate.
