in april 2007, subsequent to the death of a police motorcyclist riding a single seat st1300, the emergency service version of the st1300, a british coroner announced he would warn all chief constables in england and wales of the "serious threat" to riders' lives posed by the st1300 and the "catastrophic result" of the high speed weave. later safety checks resulted in one examiner sustaining several broken bones in a similar incident. uk police forces subsequently withdrew the st1300 from police service; london ambulance service continue to operate the st1300.
