Yamaha MotoGP stars Valentino Rossi and Jorge Lorenzo played a starring role in the official unveiling of🍃 the new YZF-R1 at the EICMA show in Milan.

The Japanese factory had also called upon nine-time world champio⛄n Rossi to help them develop the new mac🐭hine, with the Italian delighted by the end result.

"I want to say a great thank you for involving me in this important project to develop the new R1 for all the Yamaha riders," Rossi said at the unveiling. "It was great. I like a lot to work and improve the bike, especially because the target is to make the R1 as much as♌ possible like the M1 - my favourite bike!

"I think we did a great job. The bike is fantastꦰic. I rode it for the first time on the racetrack in a secret test last year. It was very funny and here is the result."

The new generation R1 will race in Superbike championships, with the Milwaukee team already suggesting it will rꦆun two for BSB in 2015, while the manufacturer is tipped to make a factory comeback in World Superbikes in 2016.

Yamaha describes the 199kg, 200-hors𝓡epower machine as being 'packed with MotoGP YZR-M1 technology', including a new crossplane ('big-bang') e🗹ngine, short (1.4m) wheelbase chassis and high-tech electronics.

Electr𒈔onic development is one of the crucial areas for factory MotoGP involvement and the new R1 boasts, 'a 6-axis Inertial Measurement Unit that constantly senses chassis motion in 3D, creating contꦆrollability over traction, slides, front wheel lift, braking and launches'.

Lorenzo was present at the launch to unveil a special limited edition 'M' version of the R1, including electronic Ohlins🉐 suspension and a data logger with GPS that allows for download and upload of new settings.

"This M version gives even more than the normal R1," Lorenzo said. "This is the versi🌺on for people that want the feeling and adrenaline that we feel. I wou🍰ld love to have this bike, even as a rider... It is unbelievable."

Rossi a♊nd Lorenzo will be back in MotoGP act𒊎ion at this weekend's Valencia finale, when they will battle to secure second in the world championship.

Meanwhile Hond🎉a is also keen to link its MotoGP project to Superbike machinery, with world champion Marc Marquez and team-mate Dani Pedrosa present for the unveiling of a special street legal version of th🐬e RC213V, called the 'RC213V-S':
