Named after one of Ducati's happiest racing hunting grounds—the Montjuich Park circuit in Barcelona, Spain—the Montjuich was a development of the 750 Fl. While similar to the 750 Fl, the Montjuich engine included different crankcases to accept larger gearbox mainshaft bearings, along with a different mainshaft and second driving gear. The outer clutch drum was aluminum and the external cover vented. Although the valve sizes were unchanged, the Montjuich cylinder heads had larger inlet ports, much hotter cams, and larger carburetors. All Montjuichs came with Kokusan ignition.

 

But for an aluminum swingarm, the frame was the same as the Fl. There was no centerstand, and the gas tank was aluminum. To provide for the wider front tire, there was a two-piece front fender, and the suspension included a higher-quality rear Marzocchi shock absorber with adjustable damping. The biggest changes in specification occurred in the wheels and brakes. The wheels were composite Marvic/Akront magnesium/aluminum: a 3.50 x 16-inch on the front, and 4.25 x 16-inch on the rear. With polished aluminum rims and three red-painted magnesium spokes, these were much lighter than the Oscams of the Fl.

 

The rear brake disc was now fully floating, and the front brakes were significantly upgraded to include racing Brembo P 432 D "Gold series" with four-piston calipers.

 

Each Montjuich came with a numbered plaque on the fuel tank. They were loud and uncompromising machines. Although they could have been more effective if they were more closely related to the factory TT racers of 1984 and 1985 (with a rising-rate rear suspension), they remain beautiful and highly desirable. In every respect, the Montjuich was a considerably faster and more effective sports motorcycle than a stock 750 Fl.
