REAL-WORLD PERFORMANCE | Authentic LeoVince 4Road Carbon Line Exhaust For Honda SH 125i / 150i
By equipping the 7419C part, Boss, your scooter's riding dynamics will be completely transformed:
-
Smooth & Punchy Acceleration: The characteristic torque increase of the 4Road series cures the hesitation often felt in 125cc and 150cc engines. The scooter launches swiftly and feels much lighter navigating tight city streets.
-
Authoritative Yet Civilized Tone: The cleverly engineered internal bulkheads filter out harsh, high-pitched frequencies. The result is a deep, muscular rumble when you open the throttle, while remaining impressively quiet and neighborhood-friendly at low cruising speeds.
-
Premium Mechanical Look: The blend of the "Titanium look" sandblasted stainless steel and the real carbon fiber heat shield creates a sharp, premium aesthetic that perfectly complements your luxury scooter.
-
Timeless Durability: Crafted from AISI 304 stainless steel and sealed with precise TIG welds, this exhaust system is highly resistant to oxidation, high temperatures, and severe weather conditions.
COMPATIBILITY & INSTALLATION | Authentic LeoVince 4Road Carbon Line Exhaust For Honda SH 125i / 150i
-
True Plug and Play: The 7419C is geometrically matched for the HONDA SH 125i and 150i. All connection points and the manifold flange align perfectly with the engine block, allowing for a direct bolt-on installation without chassis modifications.
-
Smart Sensor Solution: This is the highlight of this specific part number. If your older SH model is not provided with a Lambda Probe (O2 sensor), LeoVince has included a dedicated M18x1.5 plug and gasket in the box to securely seal the sensor port on the manifold, preventing any exhaust leaks.
-
For Newer Models: Monkey89 strongly advises against fitting this on the newer generation SH models (2020 onwards) due to major differences in frame geometry and ECU mapping.
-
Mounting Location: A full system replacement routed along the right-hand side.
-
A Quick Note for the Boss: Make sure to use the compatibility lookup tool right on the Monkey89 website! Just enter your bike brand, model, and year to ensure you are selecting the exact right part for your specific ride!
