Laverda Montjuic

The 1979-1981 Mk1 Montjuic was a raw-edged, minimalist, barely street-legal machine.

In 1979, Laverda’s U.K. importers, the ever-enterprising Slater Bros., decided to create a road-going version of the Formula 500. Named Montjuic to invoke Laverda’s win aboard a Formula 500 at the famed Spanish circuit, the first Montjuics were essentially Alpino/Zetas tuned to around 50 horsepower with the S1 cams, high-compression pistons, Sito sports exhaust, Jota adjustable handlebars and cast aluminum rearsets. They were shipped to the U.K. naked, where Slater Bros. fitted bodywork and a handlebar fairing from Screen and Plastics.

As a street legal production racer, the Montjuic was both a bear to ride slowly and a raging bull when given its head. Charles Deane tested one for the U.K.’s Road and Track magazine, noting that the idle was unpredictable, the suspension brutally firm, the riding position uncompromising and riding in traffic miserable as, below 3,000rpm, the “Monty” was “hunting and struggling for breath.” The engine was harsh, mechanically noisy and vibrated badly enough to destroy its headlight bulb.

But on the open road and on the track, the Montjuic’s performance was, according to Deane, “electrifying.” Power came in with a rush above 6,000rpm, running all the way to 9,000rpm and beyond (peak power came at 8,500rpm). Handling was “very well balanced and is extremely responsive to steering … changes in line are instantaneous and very positive.” The brakes required a lot of lever pressure but showed no sign of fade. Deane, as had other riders, noted some weaving in long, fast bends. This was blamed on the handlebar fairing, though the evidence is inconclusive.

A second version of the Montjuic appeared about 1982, with new bodywork and a larger, now frame-mounted fairing. Most Mk2s were also fitted with strengthened camshaft bearing caps, as were the big triples. The Mk2 was offered until about 1984.
