Although quite shy by nature, Honda teammates Ryan Hampton and Hayden Fitzgerald are certainly expressive when they don their racing leathers and climb aboard their 1000cc superbikes.
Christchurch's Hampton and Hawera's Fitzgerald have taken a little time to warm to one another, but not because there's any friction in the Castrol Honda race team pits; quite the contrary.
"It's just taken us a bit of time to open up to one another because we're both very quiet," Fitzgerald explained. "But now we get on great and share bike settings and things like that.
"I guess we're both completely different characters on the bikes as we are when we're off them. When we put on out lids [helmets], it's an entirely different story.
