Don't know how if you got to see the first race at Argentina but Johnathan Rea and Alex Lowes showed up with Retro Paintjobs are the ZX10s. Johnathan's bike looked like a ZX7 with Green, White, and blue paint while Alex Lowes bike looked like Tom Cruise's bike in Top Gun.

Cmon Ducati how about some retro paint jobs on the V4 Panigale. I sure could go for a GSE racing Ducati in Blue, Silver, and orange.
