If you like twisties stay away from going to a wider tire. It will slow the bikes ability to 'flick' from side to side. That's why you don't see 'Sport' bikes with massively wide tires on the rear. Not only that, but the 200 will outperform the 240 in the quarter due to more weight to get moving and the way a tire 'flattens' out the 200 will actually have a larger 'contact patch'.... lot of guys might argue this but it's true. Stay with the stock sizes.
