MTV Yak 410

The MTV Yack 410 was a project for a 400 cc single-cylinder trail motorcycle drawn up by Mototrans in its last phase, after the Barcelona firm was relaunched in 1978 under the new MTV marque, short for Mototrans Virgili. It was meant to give the company models of its own, so that it no longer depended on the Italian Ducati designs it had built under licence for two decades. The design used a toothed belt to drive the camshaft and desmodromic valve actuation, a Ducati trademark that Mototrans had long known. It never reached production: the banks refused to finance the cost of tooling up such an expensive project, and the company fell into judicial administration in 1982 and closed in 1984. The name is spelled Yack in the Spanish Wikipedia and Yak 410 in the cybermotorcycle.com catalogue.
