Had a great offer on a 2000 VFR800fi which i took. Traded my FZS600 in against it.
I imagine i'll be back on a Fazer in the future, when i can afford an FZ1.
For now; The VFR is a LOT of fun. Power is all down low/mid where i can actually use it, and the V4 rumble makes a nice change. Sporty position is taking some getting used-to, but i'm sure my back will sort itself out after a couple of weeks daily riding.
The only annoying thing was that; In fixing/cleaning the FZS for trade-in/sale, it looks FAR better than it ever has. Dammit.
