If it's capable, it's probably governed at 186mph stock. They started doing this a few years ago with the ZX12 and Hayabusa for fear that the american government would make them limit it lower. Something about in the early 90s the government flipped shit when cars being imported were capable of over 155mph bone stock and made them smack governors on them.
It's nothing that can't be overcome though. Look at Aprilias. Euro emmissions are less restrictive than US emmissions, but Swiss emmissions are worse than ours. Instead of making 3 different models, Aprilia made the euro model and the swiss/US model. We get the ultra shitty swiss restricted model that's only capable of about 138mph when imported. However, there's a wire on the computer harness that once you snip it, your Aprilia goes back to euro ignition and injection mapping. I was out on a ride a few years back and met a guy with an RSV Mille. He hadn't gotten the black wire snipped yet so he was stuck at 138mph max speed. A bunch of us were sitting alongside the road and I said just snip that shit already. I'm sure someone here has a knife and we can cut that wire right now. He had an "appointment" set up at the dealership for a week or so later to get the wire cut by them and wouldn't do it on his own. How fucking hard is it to cut one wire, especially when you know which wire it is?
