I went from a TL1000R to a Road Star Warrior (sportbike to power cruiser for those not familiar with the models)
I wanted something a little more laid back...where I didn't feel like the bike was wasted at commuting speeds.
It worked for a while and the Warrior gave me a smile every time I rode it.
I later decided to trade it in on the Buell I have now, because I had wanted a Buell for a long time and the 'fire sale' was on. Figured it was then or never.
In hindsight, I should have probably just held out and gone for what I want now.
