Yeah, that is true and apperently possible as the stock G50 clutch size is 240mm and earliest clutches were 180mm IIRC. But you already knew that of course
Weight of the magnesium cased 915 was about 44kg without support beam and the G50 was about 25kg more heavy iirc.
The weight is due to the alu case and that HUGE ring and pinion of the G50. Size does matter when it comes to strenght in boxes is my understanding more and more. I think a Mendeola box for instance is about as heavy as it is strong. Bearing in mind it has only 4-speeds of course so it saves the weight of the 5th gear.
