This is the third year that I've owned my roadster and I would say that I feel very comfortable on the bike, which leads to my confidence in the bikes performance during a ride.
I recently travelled to Melbourne / PI and back from Brisbane with 11 other bikes completing roughly 4800km of back country roads and highways over 6 days. I had an avon cobra on front and an exedra max on the back, the bike was carrying about 20kg of gear and a single rider.
The group was a mixture of sport and adventure bikes that included a couple of ducati multistrada's, a ktm super duke, triumph sprint and a couple of BMW 1000R's.
Typical speeds were 120kph - 140kph on reasonably rough country roads and 100kph on the highway.
The max had worn to the full extremity of the tyre and began to delaminate at the 8200km mark before it needed to be replaced. I was in a country town 300km from home and opted for a 225/55 ct when I couldn't get a bike tyre.
I've since done 1000km of rough country roads and highway cruising on the ct.
I ran 20psi and 35psi with and without a pillion to assess the handling.
At first the ct wanted to follow the camber of the road at 20psi but was significantly better at 35psi.
I've found that cornering is reliable and steady at angles that drag the pegs (and other bits) but the ct is using a 25mm (1") wide band on the side wall when pressed hard in corners.
I've got concerns about wearing out the side wall before the tread so I'll be swapping out the ct for another max pretty soon to allow me to keep sticking it to the sports bikes in the twisties



Other than that I can see that flat highway riding would be the most efficient use of the ct and if your riding style is more upright it would be a very cost effective solution.
