Biker sisters are a competitive lot with Australian, British and now American women vying for world records at all-female motorcycle rallies and parades.
In 2014 the Babe Raid rally set the record when 284 women rode to the coastal NSW town of Ballina. Record Setter officially declared the record at 221 women on 190 bikes.
In 2015, their Brit sisters broke that record when 661 women rode to the famous Ace Cafe in London to set the world record for the largest female bike gathering with 246 women riding bikes in a parade.
Last year, 1002 Aussie women from as far as Western Australia and aged 16 to 74 took back to the record at Dubbo.
Just last month the Brits won it back with 1132 women at a biker meet in Shropshire.
