Nothing is going to touch an F2 bike in terms of handling, but perhaps A Kramer HK2 would be a good choice that would be way less maintenance and still extremely good handling. They use a KTM 690 engine.
Buy-in cost for a brand new one is more than what you're looking at for that RS, (I think he's asking $16.5K) But the maintenance is going to be way less. Kramer also sells a bike with the KTM 890 motor that has 130hp and weighs 308lbs.
