figures and statistics...there is one major factor missing from the equation..wheelspin. It may well have been geared to do 160mph but getting that power to the ground would take ideal conditions. Dirt track, even the mile oval type is far from ideal when in the same era the TZ750 powered road racer was having trouble with wheelspin at 200+mph on the Daytona banking! Very mind boggling to have all that power on tap but I still think the biggest single winning ingredient was Kenny riding on the absolute limit and taking the wrecking crew by surprise
