Should Be Fun
Visitors to the IoM are often impressed by the quality of the roads on the mountain course. At ordinary road speeds they are smoother than anything you find on the mainland. However, by the standards of race circuits they are rough. Seventy odd miles at high speeds will give the average race prepared car an absolute hammering. The sort of short stiff suspension usually found on the Caterham-esque car pictured would not be suited to the mountain course at racing speeds. A better vehicle would be something akin to a tarmac rally car.
It's a good few years (OK more than two decades) since I joined in on mad sunday, but I could not believe the hammering I received on a (supposedly) road legal race bike at 140mph. The fact that the racers manage to lap at an average of close to that speed is not only tribute to their skill and the performance of the machines, but also the stamina and resilience of both rider and bike.
From what I've seen of many of the leccy vehilces they seem a little, errm, delicate. I think the race could be one of attrition rather than performance. Remember guys: if you want to finish first, first you've got to finish.
