Shaggles brings up a bike I’d totally forgotten about when I wrote my response. The buell has very similar handling to the Ninja, but trades hp for torque. It has minimal maintenance, and really great plastics in case you drop it (the paint is imbedded in the plastic, just buff the scratch out, no painting required!).
Buell only sells about 10,000 bikes a year, so finding used ones is harder than the ninja. The good news is, used ones ar often found at dealerships where people traded them in for their secodn bike. Buying new, any harley dealership should carry them or at least be able to order them (I’ve found harley dealers to be really helpful at sourcing bikes from other dealerships if they don’t have one you are looking for).
Lastly, if you find the Buell has too much of a “sit up” position for your liking, there are aftermarket bars that bring it down to ninja (or even true sport bike) levels. One of my friends has done this and she loved the effect it had. She still owns her Blast (and her Hubby started with a blast). They are good bikes.
