XR 75 & 80 RACING

The halftime XR Championship races are part of the rich tradition of the Grass Race, with two original classes for the ultimate old school mini racers:  Twin Shock  and Single Shock; minimum age 18 to enter.

*The newer class: “XR3”  If you’ve spent tons of hours and $ making your XR faster, this class isn’t for you!  If your bike is fairly stock and you haven’t touched it since last year’s grass race, or you spend as much effort on your outfit as your bike, it’s for you!  It should eliminate the need for qualifiers and give everyone a chance to ride their XR.  We’re not tearing down any motors here.  If you’re too serious about winning and your bike is too fast, we’ll bump you to the Single or Twin Shock class.  Minimum age 16 to enter XR3.

XR Class Rules:

  • Bike must be a production XR 75, or XR or CRF 80 with correct frame and motor.
  • Engine mods are legal.
  • Minibike wheels only. Due to limited availability of 16″ front tires, 17″ are legal.
  • Minimum age 18 to enter Twin and Single Shock classes; minimum age 16 to enter XR3 class.

XR Single Shock / XR Twin Shock – Prizes are Lisa’s famous custom trophies for the top 3, as well as prize money for the top 3.
XR3 – Custom trophies, no cash prizes.

All XR Classes: $25 Entry fee.  (No transponder needed.)[/vc_column_text][/vc_column][/vc_row][vc_row css=”.vc_custom_1632759963208{margin-top: 5px !important;margin-right: 5px !important;margin-bottom: 5px !important;margin-left: 5px !important;border-top-width: 20px !important;border-right-width: 20px !important;border-bottom-width: 50px !important;border-left-width: 20px !important;padding-top: 5px !important;padding-right: 5px !important;padding-bottom: 5px !important;padding-left: 5px !important;}”][vc_column][vc_separator][vc_column_text]
