16lbs SPRING – SOFT

Upgrade or replace your fork springs with this genuine set designed for A01 non-adjustable forks on Version 5 models.

• 700mm
• 770mm
(Same spring fits both sizes)

Fits the following models:
• TSX 125
• TSX 140

Spring Rate Info:
Most 2019–2024 Version 5 ThumpStars with non-adjustable forks (A01) come standard with 19lb (medium) springs.
• 16lb (Soft): Ideal for lighter riders or kids who want a smoother, softer setup
• 22lb (Hard): Not currently available for A01 forks

Note for Other Models:
For TSB 110 and TSB 125 models, there are currently no spring upgrade options available. If you’d like to adjust fork stiffness, we recommend changing the fork oil.
• Standard oil weight is approx. 10W
• For a firmer ride, try using 15W or 20W fork oil

Important:
These springs are only compatible with A01 non-adjustable forks. Please double check your fork type before ordering to ensure correct fitment.

Note:
These springs will fit both the standard coating and the blue titanium nitride (TiN) coated forks — the internal spring is the same.
