Ducati won't block Jorge Lorenzo testing Honda MotoGP bike in 2018

Lorenzo's Ducati contract does not expire until December 31 this year, but he will be permitted to ride for his new employer in the Valencia test on November 20-21 and the following week's Jerez test.

MotoGP manufacturers usually give dispensation for riders leaving for rival brands to join their new employer for the post-season tests, with their bikes running in plain liveries and the riders not speaking to the media.

When Lorenzo left Yamaha for Ducati at the end of 2016, he was allowed to try the Desmosedici in the Valencia sessions (pictured below) but not participate in subsequent private tests during the rest of the calendar year.

This season the Jerez test is also an official IRTA event rather than a private session, so Ducati will allow Lorenzo to run for Honda in both.

Lorenzo is replacing Dani Pedrosa as Marc Marquez's team-mate next year, in a reshuffle that has prompted Pedrosa's retirement.

Ducati is promoting Danilo Petrucci from its satellite team Pramac to take Lorenzo's place.

Andrea Iannone is also expected to be allowed to ride for new employer Aprilia at both tests after his split with current team Suzuki.
