Carole Nash brand ambassador, British Superbike racer Leon Haslam, will select the 12 finalists who will star in the calendar, receive a certificate, a copy of the calendar and clothing vouchers.
The public will then be invited to vote for their favourite pictures, with the top three entrants winning an overnight stay in Birmingham and tickets to attend Motorcycle Live on November 19.
The winner with the most votes gets a modelling contract for a year, a makeover, professional photoshoot and a new biking jacket, second place scores a jacket and clothing vouchers, while third gets a £100 worth of clothing vouchers.
The competition closes at noon on August 31, the 12 finalists will be notified by September 2 and attend a photoshoot on September 15 or 16.
The Carole Nash survey of more than 1000 adults asked them to rate how attractive the opposite sex appears when dressed as motorcyclists, compared to plain driving attire.
