XR50 WITH ELECTRIC START // SHOWN ON SLR.KART

Building on the success of the original package, the XR50 with electric start (ES) option adds a new dimension of practicality to competetive karting. Much like the popular TaG (touch-and-go) classes, the XR50ES allows drivers to simply reach over, touch the starter button, and go (or, in the case of the XR50Es: GO!).

RENNTECH recommends that two (2) sealed 12v batteries be used in series to help start the high-compression XR50ES. While it is true that the batteries add weight, the XR50ES hardly seems to notice - the XR50ES makes the same power as the "standard" XR50 (below) and made history by being the first 4 cycle engine to win an Open Class main at the 2007 Tulsa Shootout!

In addition to being a proven winner, the XR50ES is the engine of choice for the SLR.Club, and is used in all of that club's Safety and Speed Academy events.

XR50ES engine pkg starts at 5880 USD (does not incl. batteries or battery trays).
