I personnaly bless each new bike I buy with beer from the country of origin, Sapporo or Ashii for Japanese bikes, Becks or St. Pauli girl for BMW's I've only bought used HD's but I guess I'd use Coor's for them, I plan on a Speed Triple next, so probably Boddingtons pub ale for that, I wait till the first full moon after purchase, pop a top, drink half myself, then pour the rest over the bike, A true infidel, I agree. but it keeps me safe and in good karma with the machine soooo. for an Italian bike I'd use Martini & Rossi, as Italian beer tastes like pee.
