I modified my own ´89 PD for about $7k, plus $4k for the bike. I stripped and re-enforced the frame. Built a Chrome-moly sub-frame and designed a simple but solit pannier system. I also built a custom tripple-clamp for WP 4860 forks, which i had shortened and re-sprung by a pro. I have a 215-21 front whel with oversize spokes built for Ralley laced onto a billet Eagle hub. The bike uses a KTM Hardparts 310mm rotor and a Berringer 4-piston caliper. With a 12mm master cylinder, only 2 fingers will lock up the front wheel! Motor has re-built heads with dual plugs, 32mm carbs. The bike is rock solid and has been tested two-up, easily burns any fuel you put into it and is super re-liable. Compared to my recently purchased, over complicated 12oo gs, this is a better travel bike hands down, which is why i´ve decided to keep it

I won´t argue with the quality of HPN, their stuff makes me drool! But i also feel that it may not be necesary for just a travel bike. Depends on your expectations, really.
Just a note: I work as a Special Effects Fabricator in the Vancouver film industry. The stuff i build usually puts the well being of everyone involved into my hands. Failure is never an option! I´m fortunate to have both the tools and the skills to build my own bikes. I don´t mean to say in my previous post that these mods can be done by just anyone. I apolagise for any mis-understanding.
HPN is without a doubt the master in building off-road airheads and should be considered if someone plans on going to the extreme that these bikes are built for. That being said, i read about a guy who recently rode around the world on some kind of scooter thing...to each their own.
