I'm betting the fact that they gush about horsepower and torque on their site but don't give any 0-60 or top speed data means their performance sucks.
Also remember that the trick isn't just putting a really big engine on something - it's getting the engine to do useful work. Unless you can generate enough traction, a lot of that horsepower will just be wasted burning rubber and the bike will not come close to reaching the theoretical performance it could have with that engine.
And, while I wouldn't be especially surprised I was wrong (my automotive knowledge base consists mainly of "facts" gleaned watching Monster Garage once in a while) a 2-speed semi-automatic transmission doesn't
seem to indicate this thing was built for speed, rather than show.
Plus, it's so fat and ugly there's no way in hell it could lean enough to corner at anything like 200mph...
