If you want to see what happens when an actual astrophysicist and Formula One engineer decides the motorcycle industry isn't pushing the envelope hard enough, you look directly at the Tularis 800. This isn't a factory prototype or a well-funded corporate racing program; it is the mad-scientist brainchild of Dr. Robin Tuluie. Built quite literally in a home garage, the Tularis is the ultimate expression of the two-stroke dark arts, a one-off track weapon designed to embarrass million-dollar factory superbikes with nothing but sheer, terrifying power-to-weight math and radical out-of-the-box thinking.
The absolute lunacy of this build starts right in the engine bay, where Tuluie bypassed traditional motorcycle powerplants entirely. Instead, he shoehorned in a heavily modified 792cc to 800cc liquid-cooled, two-stroke parallel-twin yanked straight out of a Polaris snowmobile. But he didn't just bolt it in; he completely re-engineered the engine to handle the unique stresses of asphalt racing. Breathing through massive, custom-fabricated expansion chambers, this snow-machine-turned-superbike motor produces a genuinely unhinged 165 to 185 horsepower. It delivers the kind of brutal, light-switch powerband that makes even a vintage Grand Prix machine feel a bit tame, delivering a massive wallop of torque completely devoid of the electronic safety nets that modern riders rely on.
Putting that much raw, violent two-stroke power into a standard frame would be a recipe for disaster, so Tuluie designed a chassis that was just as radical as the engine. Utilizing his background in aerospace and elite motorsport, he crafted a bespoke structure using advanced cast aluminum and carbon fiber components to keep the mass centralized and incredibly low. The result is a motorcycle that tips the scales at a featherweight 262 pounds. When you do the math, the Tularis 800 boasts a power-to-weight ratio that rivals or outright beats the legendary 500cc two-stroke GP machines of the era. It accelerates with the ferocity of an open-class superbike but flicks into a corner with the physical effort of a 250cc production racer.
The reality of the Tularis 800 is that it represents the absolute zenith of garage-built rebellion. It demands a pilot with the reflexes of a fighter pilot and the physical strength to wrestle a massive-displacement two-stroke that wants to spin the rear wheel out of every corner at 140 mph. For the hardcore gearhead who grew up worshiping the smell of premix and the screech of twin pipes, the Tularis stands as a mythical unicorn. It proves that with enough mechanical genius, a snowmobile engine, and a complete disregard for convention, one guy with a vision can build the ultimate analog widowmaker.

Pretty cool. Love the be different ingenuity along with the passion they put into this bike.

But....and there is always a but, to say the bike was built to also embarrass factory backed race bikes is an empty boast.

The reason...these guys are not limited to various race series restrictions on the bikes that can be run on track. These sanctioning race organizations have it down to even the tire pressures you can run in a race. Yes, I was a bit shocked when this happened to one race team in MotoGP.
