I'm a massive moto gp ..world and British superbike fan. Being a biker myself it amazes me and the speeds and sound and acceleration are out of this world. Like someone said above though, moto 3 is the best. Rossi is a world wide phenomenon, selling more merchandise world wide than football teams. Speedway was always my first love though...until a few years ago, now my interest gets less each season, although the gp's can be brilliant with brilliant racing.
All the daft stupid rules and self interest of some, added to the boring nearly always follow my leader racing in a stadium full of old people and no atmosphere and of any sorts has started to take its toll over the last few years.. Maybe next season I won't go at all.
