Not to completely geek out, but no, that actually doesn't make any sense. Power does not equal loads (and what power was he even trying to compare? Hard to compare combustion/fuel consumption to electrical power directly...but I digress). But it does certainly sound like their structural engineers missed or underestimated something in the dynamic or fatigue loads, and figured out the structure wasn't suited for the loading conditions.
Which is a massive bummer--we've only ever known Disco Betty. But I agree, the new effects are a tremendous improvement. And we finally got to ride at night in October and WOW could you see her better! Very, very cool to finally ride at night.
