Unsupported by me until we have an official police bike with lights and sirens.
Police bikes primary function (here in the US) is traffic enforcement. The bikes are rarely used in pursuits, and when they are they are never the primary or "lead" unit. That said I would not want to see traffic cops in IVMP doing traffic enforcement with an NRG900 or Freeway for example.
As for pursuit vehicles, I believe LCPD Command staff are working on a division with special training for this. In which case a safer high speed vehicle will be used. (I am not a part of LCPD so do not quote me on this).
