You can still P&G going down a hill, just accelerate faster so the %load stays roughly the same.

The concept of adding mass to a competition vehicle is hard wrap your head around as a car driver but motorcycles have such a high power to weight ratio (even my 250) that to get even close to 80% throttle where peak ICE efficiency lies, the bike will be trying to rocket right out from under you up to a speed that is much higher than any average that you really want. Adding ballast would tame the violent swings of speed. This is why I would rather have a CBR125R for hypermiling to work on and for competition. It's peak efficiency power of 6-8 hp is closer to the demand that is needed for 50-65mph cruising. Less pulse and glide needed. The CBR250R is good at hypermiling but is also powerful enough to have passing power for out of town/ cross country trips.
