A UK-market performance version of the 500 twin developed with importer Slater Brothers, named after the Barcelona endurance circuit. It used Formula-style S1 cams, high-compression pistons, a Sito exhaust, a small fork-mounted fairing and an orange finish. Looks and ride earned it a following, though the fork-mounted fairing was blamed for high-speed weave.
