It appears a new 1/4 scale rc dirt bike has been released over in China/Asia markets by the name of Phantom 400. It is not so much new, but more of an updated version of the QRF400, hence the “400” in the name. The QRF400 was sold by HobbyKing about two years ago and was only available for about one year. This new Phantom 400 has some changes to the design including: e-gyro in back wheel, direct steering, and maybe some small changes to the frame maybe. The source information indicates scale is 1:5 but all measurements are consistent with 1:4 scale bikes. UPDATE: I have a PHANTOM400 page in the BIKES menu with more photos.
Here are a few videos of the bike demonstrating the e-gyro:
