So have I, but we were talking six day riders. Six day tracks are typically <200m. 60mph is upper limit stuff and unlikely on a track like Gent or Maastericht.
There aren't many tracks where they can max out and use the big motors properly anymore - they've pulled most of them all down. Poor old Oerkilon in Zurich apparently got ripped down a year or two ago
EDIT - he mentions 'Milano' in the article. The Vigorelli is 400m or thereabouts.
Cheers
