All MotoGP 125cc teams will be restricted to one bike per rider for the 2009 season, it was announced this morning.

The decision was made by the Grand Prix Commission, which includes race director Paul Butler and Dorna chairman Carmelo Ezpeleta, and is believed to be part of an effort to reduce costs.

The MSMA also agreed to propose to the Grand Prix Commission the following as from 2011: 4-stroke, 4-cylinder maximum, 600cc maximum engines, free chassis. A detailed proposal will be studied by the other members of the Commission.
