Gallery: KTM RC4 leaked pictures
Last week KTM leaked official sketches of the RC8's little sibling, the RC4.
The motorcycle first broke cover in 2007, testing in Cagiva Mito bodywork. On track it was only two seconds slower than the latest inline four, 600cc supersport motorcycles.
The RC4 has so far reached a top speed of 142mph and the single cylinder engine churns out a rather impressive 78bhp. And with the motorcycle only weighing 132kg, it's easy to ride fast.
