Given the option, it would be red for me. Saying that they look very proud of their bike, which is good enough for me :smile:
See quite a lot of the Polish lads on runs dressed up like that. Was often tempted to ask them if they want a hand extracting their fashion sense from their arseholes
Yellow for up to 750cc.... Red for larger and wear your mum's pudding basin if you want to look a complete prick
Eees simple. The smaller bikes should be yellow - the colour they were raced in. The bigger ones should be red. Black is more than acceptable alternative in both instances. White looks very classy on the 848 and later series. Custom colours are welcome, so long as they look tasty (but they often don't).
