Hey Marco ,
at this stage would be very early start Fri - all the way to KL.
Leave straight after the race and head towards border....stop somewhere for the ngight then back HKT..early Monday..
Unfortunately some of us have to work....
I'm off to the motogp on my d-tracker.... loading it on the overnight train from Bangers to Hat Yai on the 19th. Ride across the border and spend 2 night on Langkawi, then 2 nights in Penang before heading to KL for the GP weekend. After the GP it's 2 nights in Melaka and then down to Singapore for a few nights before riding back up the East coast and back in to LOS.
Sounds like a good trip...not to piss on your parade..but you do know you can't get a ferry across with your bike ? Its a separate service for vehicles...just a heads up....right pain in the arse getting a vehicle over to Langkawi !
