We have them, those relationships that just seem "right", that go on for years through turmoil and many, many good times. Even through downright low periods, the right partner is always there, always supportive, never judgemental or oppressive, easy to get along with. Quite often too, the right one is always a good time.
With this season winding down, I already look forward to my next season with my long term partner, my 94 R1100RS. Next year marks my 20th year with, for me, the best overall bike I have ever ridden and enjoyed. Rock solid reliable and still enjoyable as ever. Started riding it on late Oct of 94, two days after I bought it, and then got laid off of my job of 17 years. Even my mom, at the time said, "no way you're giving up that bike, you'll get a job again soon."
She was almost right. The new job came almost six months later, and I kept the bike. Now through two divorces and some minor crashes (cosmetic on the RS, busted left leg on me), it stills rides great and I still enjoy everytime I swing a leg over the seat to ride off. How about your "long term partners?"
