Paul Bird has released several pictures of PBM's new-for-2013 CRT MotoGP prototype being assembled at the team's HQ in England.

The bike - featuring a chassis developed by GPMS Technology, Aprilia RSV4 engine and the new Magneti Marelli control ECU package - will be raced by Michael Laverty.

Columbian team-mate Yonny Hernandez will continue with the full Aprilia 'ART' machine, as raced by James Ellison this year.
