According to the information we got from a respective source from the US, IJSBA and APBA are working out a formula for changing the rules in the Pro Ski Open in order to raise the competition and make fare the battle between the four strokes and two strokes. Possibly the displacement will reach the 900 or even the 1000cc. Additionally, the tuners will allow the use of aftermarket cylinders equipped with power valves. Therefore, two strokes will have the required power in order to reach the performance (acceleration and top speed) of the turbo-charged four strokes. There is no doubt that the Pro Ski class will be more fun to watch than any other class at next years World Finals.
