Madhukar, as Sudev, HVK and LOG mentioned though doable but would require a lot of patience (driving) negotiating Rohtang onwards.
From my little camping experience, since you are 3-4 folks, fresh water, some ready/easy to cook supplies, HVK, Sudev ji would vouch for it, usually August is a time for mad-cap rain in some parts and snow in higher reaches, roads would be unstable and may stop you in your tracks, these times little emergency ration is a lifesaver.
I had got these guards installed for my 800, though, never required it apart from once, make sure the fit is really good, get it done infront of yourself.
Regarding your traverse from B,lore to Manali, since all or most of your know how to drive, use that time to reach, though Surat and around some areas are chaotic due to industrial traffic, mostly these truckers are fairly disciplined your passage through this corridor will be fastest during night time, some of us who have done these routes, always prefer longer nonstop hours since it gives us lot of time when we need it.
Whats the fun if I have to park my car after 8 pm and find a bed in plains, which I usually do when I am home too |
