Hi guyz. I need ur help here. I used 2 ve 2 bikes, one ws th good old Calibre frm Bajaj n th other one ws th gr8 Pulsar 180 DTSi. Unfortunately both bikes r nw on indefinite loan 2 complete strangers who ve taken them without my permission

So at present I'm riding a scooter which they wnt even tch if I leave it without lock on th streets. But this month I wl b shifting 2 a new apartment with lots of security so I am thinking of buying a new bike. Now my question is which bike shd I go 4?
Why I'm asking this? Cz I'm going 2 start biking in th Himalayas with this one and since I ve nt dn that ever, I'm nt sure which model n make shd I go 4? Hero Honda karizma or Bajaj Pulsar 220 DTSi or th good old Royal Enfield in new avatar? Plz suggest me which one is th most appropriate 4 rough terrains that I am going 2 face in th Himalayas? And when I start going thr u can b rest assured that I wl nt stop until I reach th very top. So all th experts here who has dn biking in th Himalayas numerous times plz help me n suggest which one should I buy considering all th parameters viz, endurance, riding comfort, dependability, easy spares, mileage n many more. I am counting on u on this one since very soon i'm going 2 join u in all th future expeditions that u plan 2 set out............
