Auburn, bay, cinnamon, puce, mahogany, umber, burnt sienna, chestnut, tan, ochre, chocolate or indeed snuff-coloured.

I was going to say turd-coloured too but I didn't want too lower the tone. And its not strictly an accurate description anyway. Many turds are white - Piers Morgan for example.
I have a 1098s and a Yamaha MT01. Bikes that are not produced anymore because they were made for guys with serious bollocks. You do not have many of them these days...
If that was a hernia you'd have the perfect depiction of the Harley rider, accurate in every particular man and machine.
