I would go along with that riders seem obsessed with power and IMO the likes of Poland are able to build tracks to accommodate these rocket machines .In this country most of the power is needed to get off the start ,even then this will vary from rider to rider naturally taller heavier riders will need more than shall we say shorter lighter riders. Scott Nicholls has said this is one of the reasons he has always struggled on big fast tracks ,the natural power to weight ratio .
Look at the GP's BZ , Hancock compared to Freddie or Doyle who are natrally going to be heavier need more power to get the bike off the start.That power is then unmanageable during the race on many occasions, hence why we see bikes picking up and heading for the fence !
