KTM 625 & 640 Power differences?
KTM 625 SMC 21 kilowatt = 28.161 horsepower
KTM 640 SMC 40 kilowatt = 53.640 horsepower
How did KTM get so much power out of the 640 when they use seemingly the same 625cc engine and compression ratio? The 640 is using a 40mm Mikuni Contant pressure vs the 41mm Keihin.
