I've gotta put in a word for the Hyosung GV250 here, 125 kg, 21 kW, nice low centre of gravity and low seat.

I went our for a club ride today and the guy who was following me said to me,as we had our burgers at Okoroire Pub, "Coming down from Mamaku, I was slowly catching you and thought you must be moving on that thing, then I looked at my speedo and I was doing 140. You must've been doing more than 130!"

Mind that was slightly downhill heading north with a following south-westerly breeze, and 9,500 on the tacho. But I keep up easily on club rides, cruise at up to 120 km/hr and was taking some corners today at 110. Felt nice and comfortable. I've got a single row of chicken strips on my tires right out on the edges, and the wear area is less than 10mm away from the edge of the tread.
