IJSBA Ski classifications

[michael950]

Am I correct in the basic classifications for skis...


Stock - no modifications, as it comes from manufacturer
Superstock - stock engine with larger bore.
Limited - bolt on modifications allowed
Mod - Modified to gain max performance (porting, bolt-on, etc.)

I think rius replica is with 44 mikunis, protec pipe, 760 cylinders?

the rius boat is allowed to race stock class because it is manufactured by Yamaha of France and meets the homolagation requirements in order to be eligible to race
