-The brand-new 4-valve Daytona is as different from earlier Moto Guzzis as the 851 was from preceding Ducatis.- – Performance Bikes, April 1992.

There had been twin-cylinder Moto Guzzi roadsters with four valves per cylinder before in the shape of the middleweight V65 series, but the Daytona-s arrival towards the end of 1991 marked the first occasion the Italian firm had applied this technology to its big-bore superbike. Guzzi-s air-cooled transverse v-twin had been around in two-valves-per-cylinder form since the dawn of creation, so an eight-valve version represented nothing less than a revolutionary step forward.

The -Daytona- name was not chosen on a whim, but resulted from the success of American engineer, Dr John Wittner-s Moto Guzzis in AMA Battle of the Twins racing. Doug Brauneck had won the 1987 Pro-Twins Championship riding Wittner-s highly modified Guzzi Le Mans, so it was only natural that the factory would seek the Doctor-s assistance with the development of its new sports roadster.

Going down the four-valve route like rivals Ducati was the obvious means of extracting more power from the old pushrod v-twin, but switching to twin overhead camshafts would have resulted in an engine too tall, too wide and too top heavy. It wouldn-t have looked like a Guzzi either. So the factory adopted Wittner-s ingenious -cam in head- solution, employing two belt-driven camshafts positioned within the -V-, which acted on the valves via short pushrods and rockers.

Like Ducati, Guzzi switched from carburettors to Weber-Marelli fuel injection for its new leading-edge model, which produced 95bhp, an increase of around ten horsepower over the old Le Mans 1000. The eight-valve engine went into an entirely new monoshock chassis, while the Daytona-s styling recalled the looks of the original Le Mans of 1976.

To the disappointment of Guzzi enthusiasts everywhere, the eight-valve Daytona was soon dropped and the company returned to building a less exciting range of models powered by the old four-valve motor. Only this year, with the introduction of the Griso 8V, has it gone back to the future.

The example offered here is in fast road/race tune, featuring modified rear suspension, lightened flywheel and clutch, altered cams, stronger con-rods, re-chipped engine management system, and carbon fibre exhaust cans on direct pipes. -L238 GRO- was purchased from the then importer, Three Cross Motorcycles, which had developed it in conjunction with Guzzi racing specialists Raceco. Never raced, this unique Moto Guzzi Daytona comes complete with its original -chip-, air filters, exhaust system and spare cables.

The machine has covered a little over 5,000 kilometres from new and is presented in excellent condition. Offered with Swansea V5.
