the motor is 19.7mm taller, for those who are metrically impaired that is under one inchdrhonda said:Someone correct me if i'm wrong but the weight differences between the two are marginal K24 is like 3 inches taller. Weight wise i don't believe its a big deal. maybe 5-15lbs. if that.
the motor is said to be AT MOST 15lbs heavier then the K20, which i dont even see being possible
