Do you want to fall down and scratch your bike?
you've missed your calling bora- your a salesman through and through! All the routes are doable, in an upright position,most of the time. depending on your ability and the bike you choose to take.
A route- i would recommend a full on dirtbike with a plate ie: ktm exc, dr-z's will make it,bmw 450x( don't forget your skid plate), husky's(probably take the 630 on a different route) husaberg"s and beta's will be fine.
B+ route- A route bikes, and we know it can be done on a 690 enduro, as the loon's that laid it out ride them, A good rider on a xr650l, dr 650 style of bike should be able to navigate through as well.
A & B+ is not klr friendly, matter of fact- very klr unfriendly. The bug's will eat you,before you get out of there!
Here I was, going to take my xr650l on the B+. I'm going to have to downgrade. Going to be fun either way!!
