A nine-times World Champion, Rossi is one of the globe's most famous sportsmen, he captures the great era of MotoGP we are currently in.

The money raised from the sale of the bike will benefit Italian charity, La Gotita Onlus,  which supports the educational, social and economic development of children in need.

Yamaha has donated a YZF-R1 2015 Movistar MotoGP replica motorbike which features the Movistar Yamaha MotoGP 2015 colours, which is not available on the market.

The bike can be taken for a spin, or would indeed not be out of place in a private or museum collection.

As well as Rossi's autograph, the £15 000 bike technical specs are:

- New 998cc 200PS crossplane 4-cylinder engine

- Highly advanced electronic control systems

- 6-axis IMU with Gyro/G sensors for 3D motion data
