I think I asked BV to include such a roll of honour on their website last year. But I can't find it if they have.
The only reference I can find is on the Peter Craven page on Wikipedia...
"Since 1967, there has been a Peter Craven Memorial meeting held intermittently at the Belle Vue Stadium in honour of his memory. Winners of the Memorial have included World Champions Ivan Mauger (the inaugural winner), Ole Olsen, Peter Collins, Greg Hancock, Jason Crump and Chris Morton"
Jason Doyle has won it [edit] twice four times and Brady Kurtz won it last year. I'm sure other fans can fill the blanks on recent winners at least.
