Radical by identify radical by nature. If you wish to personal one of the crucial highly effective {custom} Moto Guzzis on the road there’s one man to speak to. His identify is Stefan Bronold, the proprietor of German workshop Radical Guzzi.
Upholding such a popularity takes a number of arduous work. So in an effort to retain his crown because the go-to high-powered Moto Guzzi man, Stefan has been competing within the Glemseck 101 and Sultans of Dash drag race collection. This bike named ‘Cento Anni’ has been in growth for the previous 2 years and on the latest Glemseck 101 races, he unleashed it on the 1/eighth mile observe the place it achieved some spectacular outcomes.

Essentially the most highly effective avenue bike to ever roll out of the Guzzi manufacturing facility is the brand new V100 Mandello. Powered by a 1042 cc, 4 valve per cylinder v-twin it produces 115 hp and 102 Nm of torque. Again in 2004, Guzzi launched a potent track-only bike named the MGS-01 Corsa. That bike made 122 hp and 112 Nm from its 1225cc motor. As compared, Radical Guzzi’s Cento Anni produces an unimaginable 165 hp and 200 Nm of torque…on the rear wheel.
The engine powering Cento Anni is a Frankenstein design of Stefan’s personal creation. “On the coronary heart of the efficiency upgrades is our self-made 1702 ccm 8V Motor,” he says. “It’s the most important air-cooled European 2-cylinder motor in existence.” Now that’s a title price declaring!
Beginning out with a set of modified California 1400 circumstances Stefan crammed them together with his personal formulation of {custom} efficiency elements. Contained in the beefy v-twin, you’ll discover a efficiency crankshaft, cast pistons and rods, and bespoke camshafts. Feeding every of the behemoth cylinders are FCR Keihin carburetors which inhale by open-mouthed velocity stacks. The exhaust is unsurprisingly {custom} too, the headers are constructed from titanium to maximise energy and decrease weight they usually put on an Italian-made Mass exhaust muffler.
With such an enormous v-twin sitting inside its rails it’ll come as no shock this bike’s body is {custom} too.
As soon as once more Stefan kicked issues off with a inventory Moto Guzzi Bellagio 940 chassis. In the beginning the roadster/cruiser body was modified to permit the 1702 cc engine to be shoehorned in. Stefan then centered on revising its geometry to swimsuit the mission’s trendy cafe racer theme. The outcome was a wholly new rear subframe which has established the extent bone line synonymous with cafe racer model.
With a lot energy on faucet Stefan’s put collectively a greater than satisfactory dealing with bundle. Smoothing out all of the bumps are premium suspension elements from Wilbers. The upside-down entrance finish sits in custom-made alloy triple clamps whereas absolutely adjustable mono-shock helps a mirror-polished single-sided shaft drive swingarm.
Slowing down isn’t one thing you need to disregard when drag racing and it actually hasn’t been missed right here. The {custom} brake bundle makes use of a single Brembo caliper on the rear and twin Beringer stoppers up entrance. The rotors are floating wave gadgets by Galfer and the controls and reservoirs hail from Beringer. As if all that wasn’t sufficient Stefan has additionally lowered unsprung weight drastically with the fitment of Rotobox cast carbon ‘Bullet’ rims.
Sitting atop the revised body is custom-made Radical Guzzi aluminium bodywork. The slender gasoline tank is quintessential cafe racer. Constructed lengthy and low it sits flat on the body and deep knee indents intensify the massive heads of the longitudinal v-twin. Behind the tank sits a {custom} wasps tail rear cowl reduce to observe the aggressive upward angle of the subframe.
Though constructed with Dash Racing in thoughts Cento Anni is provided for avenue using. For that purpose, the LSL clip-on handlebars put on a full set of Renard Speedshop switchgear. The bar finish mirrors and switch alerts are by Motogadget. The big tachometer sitting over the headlight incorporates a speedometer into its design and there’s a license plate holder and dual-function lighting within the rear. Impressively this custom-made beast is 100% street-legal. Making certain that their bikes might be registered is one thing Radical Guzzi pleasure themselves on – and it’s no imply feat contemplating Germany’s strict TÜV homologation legal guidelines.
Seeing as this mission kicked off in 2021, the 12 months of Moto Guzzi’s Centennial, Stefan determined to theme his mission in recognition of the event. So as soon as every little thing had been check match the bodywork was handed over to his good buddy Herbert Franz. Utilizing an airbrush and loads of gold leaf Franz hand-painted the bodywork. The completed design options portraits of well-known racers and engineers from Moto Guzzi’s historical past books together with an illustration of the corporate’s well-known Mandello del Lario headquarters.
On the 2022 Glemseck 101, Cento Anni took out 1st place within the Dash Beast class and 2nd within the Rocket class. In gentle of that, I believe it’s honest to say that Stefan and Radical Guzzi’s reputations stays intact.
