Lazareth LM 847: The Motorcycle Powered by a 4.7L Maserati V8 Engine

Mechanical Madness - When talking about motorcycles that blur the line between art, engineering, and insanity, it's impossible not to bring up creations that push every known limit of design and performance. In a world where customization often leans into subtlety and refinement, some builders choose instead to throw caution to the wind—and fuel on the fire. That’s exactly what French customizer Ludovic Lazareth did when he unveiled a machine that looked more like a concept from a dystopian sci-fi film than a street-legal motorcycle. Welcome to the world of the Lazareth LM 847, a vehicle that still turns heads nearly a decade after its jaw-dropping debut in 2016.

Built around the heart of a Maserati Quattroporte, the LM 847 is a monument to mechanical audacity. Lazareth didn't just borrow the spirit of a sports car—he transplanted its very soul. At the center of this beast roars a naturally aspirated 4.7-liter V8 engine, a 32-valve powerhouse capable of unleashing 470 horsepower at 7,000 rpm and 620 Nm of torque at 4,750 rpm. Originally designed for a luxury sedan, this massive engine now sits exposed, right beneath the rider, in a layout that defies conventional logic and aesthetics. It’s raw, it’s aggressive, and it doesn’t pretend to be anything less than outrageous.

With a build that stretches 2.6 meters in length and tips the scale at around 400 kg, the LM 847 is no lightweight. But despite its heft, it doesn’t sacrifice performance. Instead of opting for a traditional multi-gear transmission, Lazareth chose a single-speed gearbox paired with a hydraulic clutch, simplifying the drivetrain and focusing all that monstrous power through a chain to the twin rear wheels. Yes—twin. Because if one tire wasn’t enough to keep this machine grounded, two certainly make a bold statement.

From an engineering standpoint, the use of dual wheels both front and rear isn’t just for show. Stability and balance are essential when dealing with this level of power and weight. The front end features massive 420 mm Brembo discs with eight-piston Nissin calipers, while the rear relies on a 255 mm disc setup with four-piston Brembos. Suspension is handled by TFX at the back, ensuring the LM 847 can tame even the most uneven roads—should anyone be brave enough to ride it that far.

What truly sets the LM 847 apart isn’t just the numbers or its bold appearance, but the philosophy behind it. Ludovic Lazareth isn’t new to the world of wild builds. The French designer has built a reputation on his ability to merge automotive components with two-wheeled platforms in ways most wouldn’t dare. From flying motorcycles to military-inspired concepts, his workshop is a laboratory of bold experimentation. But the LM 847 was something else entirely. Revealed at the 2016 Geneva Motor Show, the bike quickly became a centerpiece—not just because of its specs, but because of its sheer presence.

And while questions remain about its roadworthiness, production plans, or even its test results, that was never really the point. The LM 847 wasn’t created to dominate racetracks or fill showroom floors. It was built to show what happens when imagination is allowed to run free, when performance is measured not just in horsepower but in sheer spectacle. It’s a rolling work of art, an engineering challenge brought to life, and a statement on the limitless possibilities of custom motorcycle culture.

Even today, long after its first appearance, the Lazareth LM 847 continues to inspire and provoke conversation. It’s proof that in a world full of safe, sensible choices, there’s still room for something truly wild.

Kept spur your adrenaline on the power of two-wheeled monster and stay alive with the true safety riding. May God will forgive Your sins and so does the cops..... *** *** [EKA [10062016] | FROM VARIOUS SOURCES | AUTOBLOG | MOTORCYCLE ]
