This is insane ... wheelies at 270 Km/h

yes the speedo speed is believable. but that really means the other vids speeds are probably accurate too ,cuz those guys were on a straighter road where higher speeds can be achieved.

MAN, for bout 10k U.S. a guy can get a bike that can do these insane speeds that even your average ferrari couldnt do. IT takes a million dollar McLaren or Bugatti to get the acceleration these bikes can do. zero to sixty in like 3 seconds. AMAZING. and addictive no doubt.
