1000 kms. Wow the number looks so appealing
But the first and foremost thing to take it into consideration is the bonding between the bike and the rider. This long ride might teach you lot of lesson than you expect.front shock absorber for bike manufacture
So for the ride:
You gotta be sure abt the climatic changes throughout the way.
Proper gear and accessories (original biker helmet preferably)
Overhaul and change oil before the trip (just before a day)
Puncture kit and learn to fix the tyres
Your hale health (keep urself well fed and watered even a week before the trip)
Carry yout confidence and the "never give up" attitude wjth you (without fail)
PS: Bikes do communicate with us so be keen to observe its need on the go. Keep your bike happy it will return the same to you.
All the best for your trip. 1000kms are very much achievable
