I have ridden friends/family motorcycles (Goldwing/Harley) occasionally for the past 30 years but haven't owned a sport bike since the cbr900rr was new. I think I dated myself with that. I'm looking at getting a 400 or 650 in the next couple weeks as a daily driver for various reasons that all in my mind justify the risks associated. I'm looking for input on pros/cons of each bike. MPG of 400 is great but power to weight is better on 650. I have a 1000 HP 6.0 powerstroke so obviously into power but not the real purpose of this venture. Plan on always riding in full gear rain or shine so input on comfortable and functional gear is welcome. Don't plan on taking a slide but who does, my moto that I try to apply to everything is I would rather have it and never need it than need it once and not have it.
