Turning a classic inline-four Japanese motorcycle into a modern custom doesn’t sound like the easiest task, but the results can be truly satisfying. Just take a look at this 1976 Kawasaki Z900 that Spanish custom builder La Perra Bikes recently finished.

At its base, the bike remains the same, so the low bars and black wire wheels, Ohlins inverted forks, Brembo radial brake calipers as well as the wavy Galfer brake rotors help bring it back through the living. Once there, the chopped exhaust should make sure everyone hears it roar.

All in all, this looks like a short way from classic to custom, but it is the black and gold combination that really makes a striking difference.
