The HENGJIAN water blocking rubber S7-Z300-13.1-09 (7) is an OEM sealing element designed for the Hengjian S8-Z300 rear fender front section, helping to direct water, mud and debris away from sensitive components around the rear of the motorcycle.
Key Features

Benefits in Use
- Supports more effective water and mud management around the rear wheel area, which is especially important in wet, muddy or rocky enduro conditions.
- Helps maintain cleaner operation of the rear shock and linkage region, which can contribute to more consistent suspension performance over time.
- Protects wiring, connectors and other small parts routed near the rear fender front section from direct spray and contamination.
- Maintains the original appearance and functional integrity of the S8-Z300 rear bodywork by restoring the designed sealing line between fender and frame components.
Typical Use Cases
- Replacement for a cracked, hardened, torn or missing original water blocking rubber on a Hengjian S8-Z300.
- Restoration projects where the motorcycle is being returned to factory specification after intensive off-road use.
- Preventive maintenance during rear fender, subframe or shock service, when access to the original seal is already available.
- Preparation of a race or training bike for riding in rain, deep mud or frequent water crossings where additional splash protection is beneficial.
Installation Notes
The water blocking rubber is shaped to follow the contours of the rear fender front section and the adjoining chassis typically follows the same routing and contact points as the original part, ensuring a snug fit and effective sealing once the rear fender assembly is correctly positioned and fastened.
