But back the the brand new G2. It comes in 115 HP high output, 140 horsepower and 150 horsepower flavors. The 115 H. O.
and 140 are differentiated mainly by tuning, while the 150 enjoys a trick piece of additional hardware: the RAVE, or Rotax Adjustable Valve Exhaust. This is an electronically managed blade on the exhaust port that makes it possible for variable exhaust port timing and variable compression. The indisputable fact that the 150 required the RAVE valve to hit its power rating is a clue that this 150 is actually at about 150 horsepower, as adversarial to, say, my old 150 V6, which cheated the 10 % allowable version on horsepower ratings for all it was worth.
