Polini Thor 202

The Polini Thor 202 is a compact, high-performance paramotor engine delivering 33 horsepower and weighing just 37 lbs (16.8 kg). Designed for balance, stability, and adaptability, the Thor 202 is now available with two carburetor options: the Dell’Orto VHST 28mm and the Tryton.

With an updated muffler geometry for improved ignition timing, optimized fuel performance, and smoother thermal control, the Thor 202 is built for consistent power delivery even under changing altitudes or weather conditions.

🔧 Engine Specifications

• Displacement: 205 cc

• Bore x Stroke: 2.60 x 2.36 in (66 x 60 mm)

• Weight: 37 lbs (including radiator)

• Horsepower: 33 HP @ 8000 RPM

• Static Thrust: Over 198 lbs (90 kg) with a 51-inch (130 cm) propeller

• Fuel Consumption:

  • Dell’Orto: ~0.63 gal/hr (2.4 L/hr) @ 5000 RPM

  • Tryton: ~0.66 gal/hr (2.5 L/hr) @ 5000 RPM

  • Both deliver ~66 lbs of static thrust at level flight

⚙️ Muffler & Exhaust System

Polini’s new 2-stroke muffler system uses a compact expansion chamber to deliver stable, progressive power throughout the RPM range. The system is mounted with a spherical coupling that allows full movement, reduces vibration, and prolongs muffler life. The revised geometry also improves scavenging and thermal performance.

🥇 Carburetor Options

Tryton Carburetor

• More stable performance in changing altitude and humidity

• Uniform fuel flow = smoother combustion and throttle response

• Built-in sealing prevents fuel leaks when the engine is tilted

Dell’Orto VHST 28mm Carburetor

• Refined fuel atomization for greater throttle control

• Lower fuel consumption through efficient Venturi effect

• Can be paired with Polini’s remote choke control for harness operation

• Ideal for precision pilots and long-distance cruising

🌬️ Airbox & Intake System

• Advanced airflow geometry reduces turbulence using an S-shaped internal duct

• 30 PPI open-cell foam filter for clean airflow

• Compact and 1.77 inches (45 mm) closer to the engine for reduced drag

• Easy-access filter cage with tool-less service design

❄️ Cooling System

• 16-core compact radiator (11.8 × 6.7 in / 300 × 170 mm)

• Eliminates need for expansion tank to save weight

• 1.4 bar (20 psi) pressure cap to regulate coolant volume

• Blue silicone hoses for improved durability and visibility

💨 Reed Valve System

• 6 carbon-fiber petals with calibrated elasticity

• Direct crankcase intake for optimized responsiveness

• Designed for consistent performance at all RPM levels

🧱 Crankcase & Build Quality

• Die-cast aluminum with high silicon content

• Precision CNC machining for stable long-term tolerances

• Reinforced zones in high-stress areas

• Expected TBO (Time Between Overhaul): 300 hours

🔁 Crankshaft & Clutch System

• Top-grade steel and thermal treatment

• Perfect centering to eliminate unbalanced vibration

• Housed centrifugal clutch allows the prop to idle at low RPM

• Oil bath gear reduction with helical teeth (reverses prop rotation and reduces torque kick)

• Built-in countershaft minimizes vibration for smooth flight

⚡ Ignition & Starter

• Inductive electronic ignition â lighter and more compact than Thor 200 HF

• Manual Flash Starter with reinforced internals

• Ergonomic pull-handle for easier grip

• Compact ignition system allows engine to sit 0.63 in (16 mm) closer to frame

🔩 Universal Mounting

All Thor engines, including the 202, share identical mounting points. This simplifies installation, frame compatibility, and future upgrades. The Thor 202 ships fully assembled with all necessary installation hardware.

Import Tariff Notice: Our engines do not normally incur a tariff; however, they may. If a tariff is incurred on the import of these engines, it will be billed to the end user — either by the shipper, or by us if we import the engine directly. These engines are not kept in stock and are usually shipped directly by the manufacturer.
