I don't know what stats you are looking at but there were only 58 finishers in last year's second Supersport race, 12 less than in the first race.

I also find it hard to believe that everyone is so negative all the time about the TT. There is nothing in the press release to suggest that the sidecars will lose a race in the future yet you're already making assumptions. I know for a fact that TT2006 will have one of the strongest sidecar line ups it has ever had (arguably its best ever) and there are absolutely no plans to shelve a race in future years. The TT organisers know how important the chairs are and have been working hard with the drivers to make them even stronger - they will always have their two races.
