Rizla Suzuki's Loris Capirossi has become the first rider to suffer at the hands of the new MotoGP engine change limit.
A maximum of five engine changes are allowed for each rider during the final seven rounds of this season.
Capirossi needed a sixth engine for Sunday's Australian Grand Prix and has thus been demoted to the back of the grid, while Suzuki will suffer a ten point penalty in the constructors' championship.
Capirossi had qualified 13th.
In 2010, the rules will demand further increases in engine life with each rider being limited to six engines for the whole 18-race series.
