UMA RACING 34MM HIGH FLOW DUAL INJECTOR READY THROTTLE BODY KIT AEROX V2 / NVX / NMAX V2

The UMA Racing Throttle Body Kit (34mm) for the Yamaha Aerox 155 V2 (and NMAX V2) is a precision-engineered induction upgrade. By increasing the intake diameter to 34mm, it significantly boosts airflow compared to the smaller stock unit, making it an essential component for riders seeking maximum acceleration and top-end power.

Key Features & Benefits

• Massive Airflow Increase: The 34mm bore allows a higher volume of air to enter the engine, which is critical for improved combustion efficiency and higher peak horsepower.

• Sharper Throttle Response: Designed to eliminate throttle lag, this kit provides immediate acceleration and a more connected feel between your hand and the engine.

• Dual Injector Support: Like other UMA racing kits, this body features a fuel injection port that moves the injector upstream. This improves fuel atomization with the air for a more consistent power stroke.

• Premium Build: Constructed from high-quality cast alloy, it is lightweight, heat-resistant, and durable enough to withstand the demands of competitive racing or spirited street riding.

• Variable Tuning: Offers flexibility for tuners to adjust the setup to match other modifications like big-bore kits or racing exhausts.

Is this right for your Aerox?

• The “Sweet Spot” for Performance: The 34mm size is widely considered the ideal choice for “Street-Plus” builds. It provides a noticeable boost over the 32mm version without requiring the extreme engine modifications often needed for 36mm+ bodies.

• Required Support Mods: To fully realize the gains of a 34mm throttle body, you should ideally pair it with a Racing ECU (like the UMA M5) and a High-Flow Air Filter.

• Airbox Note: If you plan to keep your stock airbox, you will likely need to modify the box or use a larger intake hose to accommodate the increased diameter of the 34mm air funnel.

Expert Guide Note: Because this kit significantly changes the air-to-fuel ratio, ECU re-tuning is mandatory. Running this without a proper tune can cause the engine to run lean, leading to overheating or potential engine damage.

Are you planning to install this on a stock 155cc engine for better pickup, or are you pairing it with a 63mm big-bore kit?
