This is the XRAY XB4 2WD 1/10 Scale Competition Electric Buggy Kit, specifically designed for high traction conditions. The XB4 2WD is a typical XRAY car – a premium, professional, high competition model racing car for the most demanding racers, developed and designed with attention to the smallest details. Manufactured from premium European materials, machined using state of the art Swiss and German machines and backed by premium service & support, the XB4 2WD is a typical XRAY, a luxury masterpiece.

One Platform. Two Worlds. 
One of the main advantages of the XB4 2WD is the almost full compatibility with the XB4 4WD. There are only a few parts which were specifically redesigned for the 2WD platform. As such, all the other regular spares you carry for XB4 can be used for the 2WD version as well.
