I think just about everybody goes through that at least once in their riding lifetime. My first bike (Burgman 400) I traded in after one season and 13,000 kms - and I paid a pretty penny in depreciation for those 13,000 kms on a new bike - yikes. My second bike (Kawi ZR-7S) I crashed, but I wasn't really crazy about it. On my third bike I struck gold - 2002 Yamaha FZ1 and I didn't buy it because it was my dream bike, but because at the time my ortho cleared me for riding again, it was what I could find in a sport-tourer at the amount the insurer paid out for the Kawi - lol. I fell in love with that bike big time - 7 years and 160,000 kms later I seriously considered putting in the money to keep it on the road for another season or two. But... I thought I wanted to downsize and went with a newer, low kms FZ6R - and the jury is still out on this bike. Lacking in the high end power - but so much fun in the twisties I almost forget that until I hit the highway again.
Unless you only do one style of riding, I agree having a one-size fits all bike is hard. At first I almost hated FZ6R - but am learning to embrace the revs, stop looking for a 7th gear and accept that first gear on this bike is strictly for stopping and starting.
But in the end its just a motorcycle - not a spouse. You don't have to love it forever, if it doesn't suit you there's probably someone else out there who would be happy to ride it.
