Las Vegas Motorcycle Auctions show strong results, easy access

Results are in for Bonhams fourth annual Las Vegas motorcycle auction, and the ancient British firm sold a whopping $3.3 million worth of motorcycles at its Thursday night event at Bally's on The Strip, with some fairly high-dollar bikes setting records.

Next-highest seller was a 1940 Harley-Davidson EL from the Pierce Family Museum Collection that sold for $159,000.
