Transponder for sale - $300.
I purchased this about 1 1/2 years ago and only used it for about 15 races. (I rented one for a while before purchasing one).
It's in perfect condition. Never crashed. Still blinks 4 green blinks at full charge.
Incidentally, if u need it this weekend for MSRH, I just fully charged it yesterday, so it's 100% ready to use.
Comes with the original box and everything that was initially included: Including wall charger, car cigarette lighter charger, and mounting hardware to secure to bike.
It's in Austin.
