You might try giving CSC a call and see about swapping your RX4 in on a SG400; it's definitely small enough for you and light enough, with about the same HP as the RX4, but with a different character and powerband due to it being a parallel twin configuration. It doesn't have any cargo carrying capacity, apart from what you can strap to the back seat behind you, but otherwise it will pretty much handle anything that you throw at it - check out ChopperCharles' ride report on his last year over on ADVRider:
