I’d agree that the overtaking in bike racing isnt as exciting – passes are almost always done under braking for a slow corner, defending is pretty much non existant and theres moves every lap. The real excitement in it comes from the battles, with different riders counter attacking or pressuring the guy in front until he bins it (which happens surprisingly often).
As other have said there are the battles between Rossi and Lorenzo at Catalunya in ’09, and the Stoner and Rossi at Laguna Seca the year before (That race is a blinding example of two riders being on a totally different level to everyone else)
The first MotoGP race I ever watched was the first race of 2005 – infamous and exicting for this moment on the final corner: http://www.youtube.com/watch?v=9m35LqM3kto
Or my absolute favourite, the battle between Rossi, Kenny Roberts Jr. and Toni Elias at Estoril in 2006. I can’t find a video of it anywhere, which is annoying, as it’s the most unbelievable race I think I’ve ever seen.
I understand it’s not for everyone – I have no interest whatsoever in road bikes – but there are a lot of genuinely exciting races every year. Even last year, which was a naff season, had a couple of blinders.
Of course it has its issues – the lack of manufacturers and a tiny grid is a huge downer, but watch an entire season and you might just enjoy it.
