From FREEing. The motorbike that completed the 2013 Isle of Man TT, the TT-Zero 13, has been further upgraded and made into the TT-Zero 13: Kai, which measures just over 7-1/2" long! Various parts have been upgraded in order for the bike to take part in the Pikes Peak Hillclimb and the design and paintwork of the bike has been redone with the 2014 design of Racing Miku (sold separately).
