Hello friends,
Choose a bike which is suitable for your hight and weight. Otherwise you will face back pain and wrist pain problems.
If you want to modify your bike choose the light weight material parts to get mileage.
If you are riding for a long drive, then give a regulat intervals for your engine to get cooled.
Use the same brand engine oil for your engine durability. And fill the petrol from only one petrol bunk I mean like HP or INDIAN OIL os RELIANCE etc. It will gives you more reliability for your engine.
