The next group of rippers just got underway today up here at Mammoth Mountain. Both days of the FMF Mini Days are reserved for, you guessed it, mini bikes. For the first time since the Mammoth Motocross began in the late ’60s, 50cc riders were allowed to compete along with the typical 65cc and 85cc classes. Some of the stars of the day were the Massachusets rider aboard his KTM 65SX machine, Jake Pinhacos, along with the scary fast Chris Alldredge, and holsehot artist Troy Graffunder. Here is a quick photo gallery of the events one of the most picturesqe tracks in the country.
