Use 20W50 engine oil, lubricate the chain as well... Don't ride for more than 2 hours continuously.... Take break, Have puncture kit with you, Make sure your bike brakes and lights are all in good working condition, Take a towel, fold it and put it on bike seat.... It will make bike seat more comfortable. I just did the trip from Islamabad to Teobat (AJK) and covered about 700KM in 4 days. Bike riding is fun once you make proper arrangements.
