Engineered as a direct-fit replacement for worn or damaged exterior components, this aftermarket Up Thort Housing is specifically developed for the SYM Symphony 125I ST 125cc scooter, covering model years 2017 through 2020. Cross-reference OEM number: 53168-H09-000.
The upper throttle housing serves as the top cover of the throttle control assembly, incorporating the cable entry point and the throttle tube retention features. It works in conjunction with the lower housing to maintain proper throttle tube alignment and smooth rotation.
Technical specifications: Material: ABS plastic, 20% glass-filled | Color: black | Cable entry: integrated ferrule seat | Mounting: 2x M5 screw bosses | Weight: 38g | UV resistance: UV-8 rating per ASTM D4329 | Dimensional tolerance: ±0.15mm
Installation guidance: Position over the throttle tube with the cable ferrule seated in the entry channel. Align the screw bosses with the lower housing. Insert and tighten the M5 screws evenly to 4-5 Nm. Verify no interference with brake lever operation.
Replace when the cable seat is cracked, when the screw bosses are damaged, or when the housing no longer maintains proper alignment between the throttle tube and the grip.
This is an aftermarket replacement part, not an OEM genuine component. SKU: SYM-001114.
