There's no end of great used 600 class machines that'll run well over 130 MPH. The RE 650 Interceptor has an 850 kit available also. The Honda CB500X is nice and under $5k used now. There are TDM850 Yamahas that show up fairly regularly.
The Leoncino is supposedly about 75 pounds lighter than the RE650 and makes about the same power, always nice.
