my farkling list:
Barkbuster or TT handguards, TT headlight guard, sw motech skidplate, holan pro's or sw motech crashbars,
for offroad action I wouldn't change the windscreen, neither would I change the seat. Otherwice bmw comfort seat and TT windshield.
but that's what's great about farkling: make your own bike like you please. at the end you will have your own personal farkling stuff fixed to it like no other guy has.
