The geometry of a Kilo TT is perfectly consistent with a track bike. Many Kilo TTs have brakes which would be illegal but these can be removed and I believe that several forum members have actually ridden their Kilos on a track. That said, a track bike is as a track bike does. I would never say that my FTP is a track bike. It is a fixed gear bike and so are the vast majority of Kilo TTs.
