Bang for buck the 3W 80xi wins hands down, and on in cowl mufflers I don't think it makes any less power than the ZDZ 80 RVJ. Not from what I seen, but oh brother lets not go there[:@] Tuned pipes might be a different matter but c'est la vie!
They are bumping it up 5cc because like shakeelsid said its a marketing thing for sure and why not squeeze more power out of it. Keep the cost lower than the rest, well thats it, they will sell many.
Me I am holding out for the 100cc's
