Bultaco Frontera “Narcis Casas” 370cc prototype 1978
The Frontera, replacing the Matador series, were exceptionally successful bikes on the circuit and in the shops. This bike belonged to Narcis Casas, the most honoured Bultaco rider in endure. Any work carried out on his official bikes was always done with next year’s standard production bike in mind. It was on this sophisticated version of the Mk 11 that “O Rei” (the king) would achieve his seventh and last Spanish championship in 1978.
