Hi-- I've lusted after monsters for some time now and am seriously considering a purchase soon. I'd be looking at the S4R. I'm currently riding a Honda 919 and am just wondering how the S4R might compare in terms of handeling, especially in the tight twisties and canyons ? Also, is the S4R a bike that can be ridden for 2-3 hours in semi-comfort ? Thanks in advance for any comment or opinions.
