could have been a Honda RC-51, aka RVT 1000. They are a red colour, I believe there is also some black on them. Basically Honda's racing twin, which they are marketing on the street. Very fast, and very racey looking bike. They are 1000 cc twins, so they go real fast, but they have a more low end torque which still having lots of power at the top as well, with a much deeper sound than most of the common sportbikes. Especially when you put yosh pipes on them, they practically make the ground shake. Check out Honda's bike website and see if that's the one.
Could have also been Honda VTR 1000. Also a twin, with vents i think. Similiar to the RC 51, but not as nice looking, and more made for the streets than racing.
Hope that helps
