It is relevant with the fact the GN is A/ a single, B/ less powerful and C/ a Suzuki (which as everybody knows is the best brand).

But other than that, it's probably true.

That being said, I stick with the statement that a factory exhaust or at least a proper exhaust is gonna return more MPG because it gives the bike more torque before the peak torque, allowing to use a higher gear for a given hill...

I second.

Might work with a 250, I guess. They're more similar to cars in power/weight ratio than Teresa. With her, trying to accelerate gently and DWL the hills gives worse FE than P&G'y behavior and keeping the pace uphills then a big puuuuulse near the crest. If I want to be gentle for some reason (a dying belt or sprocket, or extra slippery roads), I always do a bad tank
Therefore practically the only place when I DWL is where there's a speed limit sign of 60km/h near the top of a hill. But even here I often get rid of the excess momentum before the incline and just keep her at the bottom of 5th (slight speeding after the sign, but I'm still slower than anyone else like this so I couldn't care less
), then give her gas when we're on the top and the limit is lifted. And then P&G down the other side.
OTOH, it seems P&G doesn't really benefit the GV250 at highway speeds, at least certainly not on flat. Hilly routes are probably different.
