This week's collection comes from Joe Day:

"Here are a few of my post vintage and vintage bikes. The1976 KX400 and 2006 KX450F are 30 years apart; what a difference! The 1983 RM500 is my ultimate 500 expert class holeshot machine. The 1977 RM250 is the bike I won the 250 historic expert class in 2006-'07, and the Maico is my first AHRMA racer that I will never give up."
