The Grand Prix Commission decided to introduce with application as from 1.1.2001 the following changes to the rules:

- Start of the race: a red light will be displayed for between 2 and 5 seconds. The red light will go out to start the race (no more green light).

- Anticipation of the start is defined by the spindle of the front wheel of the motorcycle crossing the line which marks the front of that rider’s grid position before the red light goes out.

- Start delayed, restart procedure: in this instance, riders must stop their engines. The start procedure will be re-commenced at the five minute board stage.

- Riders should use only the track and the pit-lane. However, if a rider accidentally leaves the track, then he may rejoin it at the place indicated by the marshals or at a place which does not provide an advantage to him. Any infringement during the practices or warm-up will be penalised by the cancellation of the lap time concerned. Any infringement during the race will be penalised by a stop & go.

- The yellow, blue and white flags will be shown waved only.

- White flag: an intervention vehicle is on the track; the rider will encounter the vehicle in the current section of the track.

- Interruption of a race during the last lap: 1) for all the riders to whom the chequered flag was shown before the interruption, a partial classification will be established at the end of the last lap of the race. “2) for all the riders to whom the chequered flag was not shown before the interruption, a partial classification will be established at the end of the penultimate lap of the race. 3) the complete classification will be established by combining both partial classifications as per the lap/time procedure. 

- Race result: in case of ties, the riders concerned will be ranked in the order of the best lap made during the race.

- Bodywork: the bodywork must not extend beyond a line drawn vertically at the leading edge of the front tyre and a line drawn vertically at the rearward edge of the rear tyre. The suspension should be fully extended when the measurement is taken.
