Right, so am just prepping for Laguna SBK next month. Should be around 6,000 KM there and back. 2007 Superduke/30,000 km. What I've done for the trip: new battery, ktm bar risers, ktm heated grips, c and j water pump kit/ fresh coolant, and a fresh oil change before I leave.

Should I change the voltage regulator just to be safe?
Any other tips on what to do / what to bring ?

Quit worrying, and bring credit cards.

tyres, you didn't say anything about tyres. What tyres will you get? What pressures will you run?
