E Street MX is excited about introducing professional quality transponders to amateur Motocross.  The MyLaps MX Transponder is the premier brand in the world, used by AMA Motocross, AMA Supercross, MotoGP, NASCAR, Motocross of Nations, etc. 

Transponders are required to race at E Street MX races. Transponders can be rented on race day for $15.

• Website Posted Lap-times for your E Street/ Riverfront main track practices
• This technology will eliminate sandbagging by bumping per lap-times.

Sharing Transponders-  2 riders can share a transponder at a race, however it is the riders' responsibility to switch the transponder to the correct bike before the rider is called to the line for their moto.  (Ie:  it is impossible to share a transponder if your motos are back to back.  It is the riders' responsibility to check the moto order, and possibly rent a second transponder if this occurs.)
