The Formula 1 and MotoGP seasons may both have come to a close – but tha💦t is not stopping the biggest star from each series hittin🧔g the track.

Lewis Hamilton and▨ Valentino Rossi will complete their hotly-anticipated ride swap next week, and while we are still waiting for any official announcement, there are a few details we can be sure of.

Hamilton and Rossi share a mutual sponsor in🅷 Monster, which has helped make the crossover a reality.

Hamilton has str﷽uggled to stay tight-lipped on the ride swap, such is his excitement for it, with the pairꦬ set to sample each other’s machinery next week in Valencia.

The test will take place on December 9, coming a little over a year after Hamilton completed some testing on a Yamaha R1M Super🍰bike at Jerez.

🔜There are no restrictions on what bike Hamilton can use, but iꦬt is likely he will complete some running on a Superbike again to warm up before moving across to a MotoGP-spec bike.

Hamilton will, however, be limited on what tyres 🦩he is allowed to use due to MotoGP regulations, which are likely to be Superbike-style Michelins, meaning it will be more😼 difficult to compare his efforts to the regulars.

But that isn't dampening the six-time F♚1 world champion's excitement for the swap💦.

"I’m going to be out with Valentino next week, which I’m a little bit nervous about,” Hamilton said following his victory in Abu Dhabi last Sunday. “That bike is going to be so fast! That’s going to be awesom✃e.”

For Rossi, this will mark his first outing in an F1 ca🥂r for almost a decade.

Despite his repeated tests with Ferrari through the 2000s – reportedly putting him close to a switch to🍸 Maranello ᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚto race in F1 – Rossi has not 💜driven an F1 car since 2010, when he completed running for Ferrari in a 2008-spec car in Barcelona.

As Mercedes has used all of its permitted promotional running permitted for this year, Rossi c🎃annot drive the 2019-spec Mercedes W10.

The most r🧔ecent car outside of the restrictions is the Mercedes W08 from 2017, which won 12 races en route to both championship wins that y꧒ear.

The test will take place behind closed doors on💫 Monday at the Circuit Ricardo Tormo, which hosted ♊the MotoGP season finale last month.
