The TVS STAR HLX100 motorcycle is typically equipped with a rear shock absorber, also known as a rear suspension. However, I don't have access to specific information about the rear shock absorber model for the TVS STAR HLX100. Here is some general information about motorcycle rear shock absorbers:

Function: Rear shock absorbers are an integral part of the motorcycle's suspension system. They are designed to absorb and dampen the shocks and vibrations generated by uneven road surfaces. The primary function of the rear shock absorber is to provide stability, control, and a comfortable ride by minimizing the impact of bumps and road irregularities.

Design: Rear shock absorbers consist of a spring and a damper. The spring absorbs the energy of the impact by compressing and then releases it, while the damper dissipates the energy by controlling the speed of the spring's movement. This combination of spring and damper helps to maintain contact between the rear wheel and the road surface, ensuring traction and stability.

Adjustment: Some rear shock absorbers offer adjustability to fine-tune the suspension based on rider preferences and varying road conditions. Adjustments can include preload (to account for rider weight and load), damping (to control the rate of compression and rebound), and rebound (to control how quickly the shock returns to its original position).

Maintenance: Regular maintenance of the rear shock absorber is important to ensure optimal performance. This may include checking for leaks, inspecting the condition of the spring and damper, and lubricating moving parts as necessary. If the rear shock absorber is damaged or worn out, it should be replaced to maintain safe and effective suspension performance.

For specific details about the rear shock absorber model used in the TVS STAR HLX100 motorcycle, I recommend referring to the official TVS documentation, contacting authorized TVS dealers or service centers, or reaching out to TVS customer support for accurate and up-to-date information.
