by both riders in the team, including the substitute or replacement riders, will count towards the team's constructors championship. If the team consists out of only one rider, the points by said rider will also count. An exception is made for wild card entries, which do not score any points. In case of an entry, a rider is considered to have taken part the race weekend if he has, at least, participated in one practice session. A rider is considered to have started a race if he, at least, participates in the first lap. For a rider to be classified as a finisher of the race and be included in the final results, he must cross the finish line on the circuit and not in the pitlane within five minutes of the race winner. The rider must, at all times, be in contact with his motorcycle also. The white line which indicates the pole position must be painted one meter before the start/finish line. From 1 January 2003 onwards, races which have changes in the climate because of rain or mixed conditions and have thus changes in adhesion of the circuit, will no longer be stopped. Technical regulations The 500cc two-stroke machines - in use since the late 1970s - are going to be phased out this season for the new 990cc four-stroke machines. Helmets must now conform to one of the recognized international standards and be of the full face type. The European standards are ECE 22-04 & ECE 22-05 'p', the British standards are BS 6658 Grade A and the American standards are USA: DOT Federal Standard n? 218/SNELL M95 & M2000. The use of materials has been restricted. The basic structure of the crankshaft and camshafts must be created from either steel or cast iron. It is not allowed to use composite structures which use either carbon or aramid fiber reinforcing material on components such as pistons, cylinder heads and cylinder blocks. It is mandatory to have brake calipers which are made from aluminium material with a modulus of elasticity that does not exceed the 80 GPA. None of the parts on the bike can be made from metallic materials which have a specific elasticity modus that is greater than 50 GPA. 2002 Grand Prix season results †† = Saturday Race Participants MotoGP participants FIM released a 20-rider entry list on 13 March 2002.
