Yeah, my other bikes are well over 100 hp (and I race them). The R3 is not exactly an overpowered beast, but big fun on the track. Great beginner bike - post photos - may help you to get a buyer.
Current price for a new 2015 Zero S start at $12,000. You might find a leftover 2014 for around $9,000, though.You bought the r3 because you wanted a lightweight bike that you can move around in the garage yourself unlike the FZ09, but the r3 is too weak for you.
I think its time to look into electric motorcycles. Light and torquey powerful. Zero S, 376lbs weight, 68ftlb torque. Comes at a premium though, around twice the price as the r3. Unless speed is also your thing then nevermind.
ps., Jen before you sell it, I'd recommend redlining the motorcycle up the gears a few times. At least feel the full power of the r3 before writing it off.
