This weekend's Czech Republic Grand Prix will be the first event run under the newly revised MotoGP tyre supply regulations.

Under the new rules every rider will now have a choice of three (rather than two) compounds of Bridgestone front slicks - an additional soft compound being made available for increased safety in the case of low ambient and track temperature.

Ten rear slick tyres will still be available in two compound options per weekend, but riders can now choose more of the tyre option they prefer, up to a maximum of six of one compound option and four of the other.

"The Czech Republic Grand Prix is the first for our new tyre supply system and I am confident that with it we will be able to answer satisfactorily what the riders have been asking for in terms of a greater choice of softer compounds specifically to improve warm-up performance," said Hiroshi Yamada, manager of Bridgestone's Motorsport Department.

"Brno is an abrasive circuit so grip is usually quite high, but I expect the softer compound options to be well used in the cooler morning sessions in particular.

"After a summer break since the last round at Laguna Seca, I'm sure everyone is recharged and eager to get back to racing and I hope that in changing our tyre supply system we can play our part in contributing to close competition and an exciting title race in the second half of this season."

Hirohide Hamashima, Assistant to Director at Bridgestone's Motorsport Tyre Development Division, expects 'quite a few riders' to make use of the softer options this weekend.

"From this race onwards our new tyre supply system comes into effect meaning that in addition to our 'core' compounds we also provide every rider with softer front slicks.

"The weather in the region can be quite cool so I hope these changes will be well received and judging by their recent comments I think we will see quite a few riders choosing more of the softer compound options."
