​Lucky Thumb Racing would like to welcome the Michigan Harley Davidson Dealers Association back as a major sponsor in 2023! When you ride into Lucky Thumb at any of our 8 races for the summer events, your gate fee is paid by the MHDDA.  Their sponsorship also allows us to have a minimum $1000 purse for the motorcycle combo class for all 8 of our summer races, paid back as $500 for 1st place, $300 for 2nd place and $200 for 3rd place.
