[igabiva28_imp]

Hello, according to someone, cross beam is used to express the placement of the 4-cylinder-in line engine whih was positioned accross the frame beam.
However most people say it does not mean nothing exactly.
I have asked to the boss of the communication for honda europ, Ian baker, I answered it was a question without solution, nobody now knows exactly what it means exactly.
Bye, enjoy your "galette des Rois" on sunday, my dictionary said cake eaten on the twelfth night (or is it only a french tradition ?)
