Hi,
Got a 6 months/12K km old P150. And my riding style is 'itchi right wrist'.
keep going on 200-300 KM weekend rides with pillion.

Last time got premium petrol and felt that the bike is better responding.
But also read, that using high octane petrol can harm your bike.

Can some one let me know, what is recommended octane for p150 and which one should I go for.

I generally go for Shell normal petrol. I am contemplating over the option of shifting to HP/IndianOil premium petrol.
