RacingBros Adjustable Front Fork Kit – Honda Grom 125 (2014-2025) & Monkey 125 (2019+)

RacingBros Adjustable Front Fork Kit – Honda Grom 125 & Monkey 125

Engineered for the Honda Grom 125 (2014–2025) and Monkey 125 (2019+), the RacingBros Adjustable Front Fork Kit delivers track-ready suspension control that the OEM setup simply can’t match. Independent ride-height tuning on both sides lets you dial in geometry for your weight and riding style, while split-side rebound and damping controls give you precision response tuning for any condition — track, street, or canyon.

Swap settings between circuits or riding conditions without tools. A massive step up from the OEM 3.9N/mm spring rate.
