Carolina Thunder Motorcycle Drag Racing

Pro Open

Pro Open  —  400 Pro Tree, All Run Field
This class will showcase the most diverse array of drag bikes the sport can provide!    Pro Open is open, actually WIDE open to ANY combination you want to bring out.    These purpose-built machines will attempt to put their massive amounts of horsepower to the ground and propel them through the 1/8th mile in search of a quick ET and high MPH.    All Retired to Present Day Funny Bikes, Pro Mod, Pro Comp, Pro Fuel Bikes, experimental Bikes, all are welcome.

If you can stuff a motor, any motor, into a chassis with two wheels in place, you can run it in the Pro Open Class. Any motor, any combination, any wheel base, any fuel, if you can build it, show up and run it. There are no special rules aside from the usual safety requirements.

There are many Older Pro Bikes including the AHDRA Pro Bikes parked since the demise of that sanction. A thundering performance from any combination is welcome here. We are hoping that a lot of the old Funny Bikes, Pro Comp Bikes and the like will come out and be part of this class. Any of them can kick some serious butt in Pro Open Class.

Remember  — These purpose-built machines will attempt to put their massive amounts of horsepower to the ground on a 1/8 mile track in search of a quick ET and high MPH.    This class will showcase the most diverse array of drag bikes the sport can provide!
