I'm married to a German, so I speak with authority on this subject.
Look, bikes are the ultimate lovers, and mistresses (or whatever the male version of that is... Boy toy ?). Never in any relationship will you wrap your legs around something and derive so much guilt-less pleasure without even raising an eyebrow of your husband,wife, girl or boy friend. (I am enjoying the visualization of a sexy German biker girl, so forgive me!
Little do they know how much these bikes feed our souls. Often bikes hold such dear memories for us, and when we are forced to let them go it tears a part of us away. I think it sad to say I have more memories of my first bike than of all my girl friends during that time. That may be because of a bikes ability to trip endorphins and adrenaline is better (and longer) than any sex kitten or puppy boy could. (I'm trying here to equate things for you incase your not also into sex kittens)
I have never sold a bike that i enjoyed and weeks or years later agreed I did the correct thing.
So here are some things to consider.......
If you can at all keep this bike do it!
If you can make the room to store it, do it!
If you sell it, write in the contract you will have first right of refusal on any resale of the bike. I am still tracking three of my last bikes I sold, calling every year or so, waiting for the current owner to get tired of my old 94 carbie monster.....
You never realize how much you miss something until it is gone.
With what I read, you will regret not disassembling, cleaning, injecting oil into the tank and engine and sealing it up for storage until you decide to sell or restore it.
But... In the end, it is better to have loved and lost than to have never loved at all.....BUT I prefer to love-em as long as I can.
