Fan wheel HEIKOTUNING (04354) - Piaggio 2-stroke 125/150 AC - CNC solid material, HPI 2TEN compatible

The HEIKOTUNING high-performance fan wheel is the clean solution if you are looking for a powerful upgrade or a high-quality replacement for the Piaggio 2-stroke 125-150 cc AC engines - especially because the original Piaggio fan wheel(Piaggio 431110) is practically no longer available. Thanks to the optimized blade geometry, the wheel delivers significantly more cooling air and can thus help to keep the engine temperature more stable even in demanding setups.

CNC milled Solid material Piaggio 431110 replacement 172-200 cc suitable HPI 2TEN PnP

Why this fan wheel is more than "just a replacement"

More cooling reserve: large blades and optimized geometry for high displacement.
For powerful setups: useful for uprated 172-200cc engines if you want to keep the temperature under control.
Stability: significantly more resilient than many standard solutions - especially with a sporty riding style and permanently high loads.
Investment in stability: stable temperature helps to keep the engine healthy and powerful in the long term.

Production: CNC solid material, no 3D printing

The fan wheel is CNC-milled from solid plastic - not 3D printed and not a "lightweight" injection-molded part - and is manufactured at HEIKOTUNING in the Netherlands. Due to the high machine running time, the fan wheel is not cheap, but you get a part that is significantly above the series level in terms of strength and long-term quality.

Solid: CNC machined from solid material - robust structure, high stability.
Quality: Manufactured with a focus on dimensional accuracy and durability.

Plug and Play: HPI 2TEN compatible

Compatibility: Plug and Play compatible with HPI 2TEN internal rotor ignition.
Tip: After installation, check clearance and check screw connections after the first few kilometers.

Suitable for

Piaggio SKR 125 / 150 (2-stroke, AC)
Piaggio TPH 125 / 150 (2-stroke, AC)
Piaggio Skipper 125 / 150 (2-stroke, AC)
Aprilia SR 125 (2-stroke, AC - depending on engine version)

Note: Please check the engine type (Piaggio 2-stroke 125/150 AC) and the existing ignition system before ordering. For conversions or mixed combinations, a comparison with the installed fan wheel/pole wheel is advisable.

FAQ

Because it is CNC machined from solid material. This means a lot of machine time - but you get high stability and clean quality.
Especially with powerful setups (e.g. 172-200 cc), additional cooling reserves can help to reduce temperature peaks. This supports stability and constant pulling power.
Yes, it is designed as a plug and play solution for the HPI 2TEN internal rotor ignition.

Conclusion

The HEIKOTUNING fan wheel 04354 is the high-quality replacement for Piaggio 431110 - and at the same time a real upgrade: more cooling reserve, CNC solid material instead of 3D printing, high stability and plug and play for HPI 2TEN. Not cheap - but a sensible investment if you want a healthy, temperature-stable and permanently powerful engine.
