Marco Lucchinelli's success in the Battle of the Twins at Laguna Seca in 1986 prompted Ducati to name the next series of limited edition 750 F1 the Laguna Seca. The Laguna Seca also came with a Marco Lucchinelli decal autograph on the gas tank.

Except for slightly different cylinder heads, the engine of the Laguna Seca was identical to that of the Montjuich. There was a steel, rather than aluminum, inner clutch drum, and small changes to the clutch actuation system. There was a new clutch slave cylinder and bearing, although the vented clutch cover was retained. In an effort to reduce noise levels, the Laguna Seca featured a new muffler, with larger canister and riveted aluminum cover. U.S. versions received a different muffler again; a Conti similar to that of the 1986 750 F1.



The frame was identical to that of the Montjuich, except for a revised footpeg and exhaust brackets, and a Verlicchi alloy swingarm that included a plastic rear fender. There as some evidence of cost cutting as the hand-beaten 'aluminium fuel tank made way for a normal 18-liter steel tank, and the wheels and brake discs came straight off the 750 Paso. These aluminum Oscam wheels had wider rims, he 3.75 x 16-inch on the front and 5.00 x 16-inch on the allowed the fitting of wider and lower-profile Pirelli tires. The same four-piston Brembo racing "Gold Series" front brake calipers as the Montjuich were fitted, but with a rectangular handlebar master cylinder. To go 'the Paso wheels, the rear P2108N brake caliper was so shared with the Paso. It was unfortunate that the Laguna Seca was burdened with these few Paso items, because they detracted from the purity of the Montjuich, and compromised the performance and handling.

The red and silver fairing, too, was revised slightly, with a narrower front oil cooler air intake and lower screen. While most Laguna Secas came with a solo seat, a number were also produced with a dual seat. All Laguna Secas came with a new front fender that was also shared with the 750 Paso.
