I've been giving this issue some thought and I haven't really found an ideal answer. It seems vaning the bikes up and down is going to be very difficult. I have made some enquiries about renting a van but when they hear you want to take it to Malaysia they simply say no.
So its either leaving the bike with someone like Barry or renting a lock-up at the circuit. Sharing the cost of a lock up would probably be cheaper but what do you do when you need work done? Someone said the rent is about RM500 a month so 5 sharing would make it an affordable RM 100 each. Leaving it with Barry will cost somewhere in the region of RM250 for a race-weekend, including a mechanics to help you and I think petrol.
We talked to them a while back and its way expensive.
They collected my Gixxer when it blew its beans at Pagoh, cost around 300 to collect from the service station and drop me off at the causway, push over from there and collect at the other side
