Racing-oriented brake stopper for Kyosho V One

This replacement pulley is engineered for use on Kyosho V One RRR and V One SIII chassis as the brake stopper in scale-model braking linkages. The 21T tooth count sets the engagement geometry used for repeatable brake response and fine setup at the track.

Fitment matches the original mounting pattern and requires only standard hobby hand tools. The component is intended as a tuning and indexing element rather than a structural load-bearing part, making it useful for precise adjustments to engagement point, return position and linkage free-play during setup and race maintenance.

When replacing the pulley, inspect adjacent linkage and any 走珠軸承 for wear, verify alignment, and confirm smooth return through full travel before high-power use. The part is supplied as an aftermarket racing accessory compatible with Kyosho V One RRR and V One SIII for model use only.

What tuning benefits does a 21T pulley give?

A 21-tooth profile refines the engagement arc, allowing tighter control of initial bite and improved consistency lap to lap when tuning brake bias and return.

Any special installation notes for track use?

Ensure precise alignment and check linkage wear points including any 走珠軸承. After fitment, validate travel and return with low-power checks before race runs.

Is this suited to competitive setups?

Yes, it is intended as a tuning item for competitive drivers who need repeatable brake engagement and fine adjustment capability on Kyosho V One RRR and V One SIII platforms.
