In the late 1980s, Italian engineer Roberto Gallina teamed up with Japanese investor Yoshiyuki Hayashi to build a limited run of high-performance motorcycles. The result was the Gallina 750 Sport, also known as the Hayashi Gallina Quattro 750 L.E. Only ten bikes were ever made.

The Team Behind It
Roberto Gallina was already well known in racing circles as an Italian Grand Prix racer and team owner. His best racing year was 1973 when he finished 8th in the 250cc world championship. Later, from his shop in La Spezia, Italy, he built a series of one-off superbikes and prototypes known for their clean design and race-level engineering.
Yoshiyuki Hayashi, based in Japan, was a motorsport enthusiast with serious resources. He owned Fuji Speedway, funded several racing teams, and collected Grand Prix motorcycles. But he wanted something more — a motorcycle of his own design. To make it happen, he turned to Gallina.
Hayashi summed up his approach simply:
“Everyone is free to have a dream, however big it can be. Once you speak of it in the presence of others, you must make it come true with your efforts.”

SELLER
1989 Gallina Quattro 750, a collaboration between Japanese investor Yoshiyuki Hayashi and Italian motorcycle racer and team owner Roberto Gallina.
The bike has a hybrid tubular trellis frame with aluminum side plates, with parts from all the foremost manufacturers like Marzocchi and Brembo. The engine was a heavily modified GSX-R750 unit, with most parts recast in magnesium and with gear-driven cams.
Power went up from 105 to 130hp. Marvic Wheels, the body was designed by Roberto Ugolini, who also did the Bimota Tesi 1D, which should come as no surprise. Built for the World Superbike championship, the Japanese economic bubble’s collapse meant that only ten Quattro 750 prototypes were finished, at a total cost of about $2.5 million.
The odometer on this bike shows 32,947 km – it has been recently serviced in including a new battery and the Carburetors cleaned. This bike has been in a private collection for over 20 years.
The Gallina has flat slide KeiHin Carbs. Recent service cleaned the carbs. New battery new plugs, Fresh hydraulic fluids, New metal dry break fuel line connections at the gas tank bulkhead.
Bike is from the A.S, Paul Collection. I’ve cared for this collection for 25 years – the attention and care for these motorcycles was incredible no expense spared. New tires in 2015, zero miles on them. Recently detailed to achieve a beautiful result

Building the Gallina 750
The goal was ambitious: create a bike that was “faster than the Japanese bikes and more fascinating than Italian motorcycles in old days.”
Gallina started with a Suzuki air-cooled 750 engine, but re-engineered it from the inside out. He recast the cases, cylinders, and head, and converted the camshaft drive from chain to gear drive — a major upgrade in both precision and durability. The frame was a trellis design, hand-built with billet-machined components throughout the steering assembly and chassis.
One detail that stands out to anyone who’s seen the bike in person: the low-mounted rear shock with a rising-rate spring setup, tucked away underneath. It’s one of those things you only notice when you’re really looking.
Every piece of the bike was hand-fabricated. Nothing about the Gallina 750 came off a production line.

A Project Cut Short
The timing couldn’t have been worse. Just as the project gained momentum, the Japanese economy collapsed during the 1990 recession. Hayashi lost his funding, and the program ended abruptly. Only ten motorcycles were finished before the lights went out.
Why It Matters
The 1989 Gallina 750 Sport never reached mass production, but that’s part of what makes it special. It’s a snapshot of what can happen when a racer’s engineering mind meets a collector’s dream — a motorcycle built with no compromises, just purpose.
For collectors and enthusiasts, these bikes represent more than rarity. They mark the end of an era when small builders could take big risks, and sometimes, even unfinished dreams left something worth remembering.
