At the first part of this series I wrote about LDR (Long Distance Riding) in general. The point being that the stock Sportster can do it easily if the rider has good attitude and doesn't want a luxury couch experience. Opinions about what is LDR do vary, for some 1000 miles in 24 hours is LDR, for others it may be a month-long journey.
But what could be done to make the journey a little more convenient? A few small and cheap adaptations might be in place. They're not going to take the wind away, they just make your life a little bit easier. These days everyone has some kind of electrical gadget. They're good but they need recharging. When camping, no electricity is available. These electrical marvels are handy on the road: GPS, radio, camera, MP3 player, internet and blog software can even reside inside one frame. But even with just one divide, you eventually need to recharge it.
I think a 12V cigarette lighter adapter is the best-value-for-money modification that anybody could possibly do. With 10-20$, you'll have never-ending supply of electricity for your gadgets, air pumps etc. Even if you know nothing about electricity, this modification is very easy to made. Auto stores also have dozens of luxury items that run on 12V, like coffee makers and such (they'll work slower than household ones).
One important, maybe too obvious, addon is the sissy bar. A huge amount of baggage can be attached at the back side of it, leaving other places at the bike free. This, of course, requires the license plate to be moved out of the way. (At least in those countries that have ridiculously big plates, Finland included)
Another adaptation that I like very much is to have the license plate moved to the left side of bike, from its original position. That way, a big amount of luggage can be attached to the back side of the sissy bar, leaving passenger seat free for some other uses. Technically it may be against the law because the plate should be visible in every direction, but I haven't heard of a case (where I live) that somebody would have gotten a ticket because of it. I guess it depends about the policy of the local law enforcement. Remember to use a licence plate light to make a good impression.
A tool roll or two might also be in order, to free your pockets from carrying the little stuff. That way, those items also are permanently with the bike and are not forgotten. They can be placed as in the link, down low, to help keep the center of gravity good.
There are more tricks, like attaching a couple of tie-down lashing straps under your seat in a way that you can attach things to the passenger seat area without needing to go look for the straps. Or just stuff them into the tool roll or into your riding jacket.
My to-do list includes at least auxiliary lightning, the standard one lamp just isn't enough. A highway bar would also be handy, never mind the aesthetics of it. It would allow some nice further modifications.
