RETROL R32 4.2cc V-Twin OHV 4 Stroke Mini Gasoline Engine Model Shovelhead Style Gift
Hero Section: The Spirit of the Open Road on Your Desk
The 1960s were defined by the roar of the V-Twin engine—the heartbeat of the "Easy Rider" generation. The RETROL R32 is a stunning tribute to that golden era, specifically modeled after the legendary "Shovelhead" motorcycle engines. This isn't just a static display; it is a fully functional, 4.2cc gasoline-burning mechanical sculpture. Whether you are a biker missing the open road or a mechanical enthusiast who appreciates the rhythm of a true V-Twin, the R32 brings the thunder of the highway right to your workbench.
Why Choose the RETROL R32?
- A Tribute to the "Shovelhead": With its distinct rocker box shape and V-configuration, this model captures the iconic look of the classic American motorcycle engines. It evokes a sense of nostalgia and freedom that plastic models simply cannot replicate.
- Brass & Steel Craftsmanship: Weighing over 1kg, the R32 is machined from solid brass and stainless steel. The contrast between the golden brass and the silver steel creates a retro industrial aesthetic that feels substantial and premium in your hands.
- Ready-to-Run Experience: We understand the frustration of complex assembly. The R32 arrives pre-assembled on a handcrafted wooden base, complete with ignition and wiring. You focus on the joy of starting it, not the headache of building it.
- The Ultimate "Man Cave" Gift: This is the conversation piece every garage or office needs. It’s a bridge between generations—a perfect way for a father to explain the mechanics of a V-Twin to his son, creating memories over the smell of gasoline and the sound of an engine.
Technical Highlights: Engineering the V-Twin
- OHV (Overhead Valve) Precision: Just like its full-sized inspiration, the R32 features a complex Overhead Valve system. Watching the exposed pushrods and rocker arms dance in time with the engine's firing order is a mesmerizing lesson in mechanical timing.
- Upgraded Carburetion: The R32 features a newly designed carburetor with a dial-type throttle lever. This offers significantly improved throttle response and easier tuning, allowing you to find that perfect, slow "potato-potato" idle that V-Twin fans love.
- Dual Start Options: Versatility is key. You can start the engine manually using the included pull-cord for an authentic experience, or use an electric drill with the coupling shaft for a quick, effortless ignition.
- Efficient Air Cooling: The deep cooling fins on the cylinders aren't just for looks; they effectively dissipate heat, allowing the 4.2cc engine to run smoothly during demonstrations.

Usage Scenario: Sunday Morning Tuning
It’s a quiet Sunday. You place the R32 on your desk. You mix a small batch of fuel, carefully fill the tank, and prime the carburetor. You connect the battery box. With a quick pull of the cord, the engine coughs, then catches. The V-Twin settles into a rhythmic, thumping idle. The smell of exhaust, the vibration of the wood base, the movement of the rocker arms—it’s a sensory experience that transports you back to the garage days of the 60s.
Important Tips from the Workshop
- Tuning the Carburetor: If the engine struggles to start, the needle valve likely needs adjustment. A good baseline is to tighten the main oil needle gently, then loosen it about 1/4 of a turn. This usually provides a rich enough mixture for a cold start.
- Lubrication is Vital: This is a miniature engine with high internal stresses. Always use a 25:1 fuel-to-oil ratio (using high-quality 2T engine oil). Never run it on straight gasoline.
- Shutdown Procedure: To stop the engine, simply turn off the power switch on the base. This cuts the ignition immediately.
- Break-in: Run the engine at moderate speeds for the first few tanks to allow the piston rings to seat properly against the cylinder walls.
