Kawasaki GSX Episode: 1.01
Kaawsaki? (suggestion: GPX 750...) Confirmation: Link to "www.echappementmoto.com"
That isn't a GPX 750. I own GPX 750 '87. That bike may be a Suzuki GSX400 or GS450, or perhaps a Yamaha XS400... with an aftermarket fairing, surely of the spanish Puig barnd, very common in Spain in the '80s
