Impaktech Adjustable Subcage Kit – Stark Varg MX & EX

Meet the world’s first adjustable subcage built specifically for the Stark Varg MX and EX platforms. We took our proven, decade‑strong adjustable subcage technology from streetbikes and engineered a solution that actually works with the Varg’s unique chassis. Because the Stark Varg subframe has no provisions for a stunt subcage, we start with a brand‑new OEM subframe, reinforce it for strength, and weld in custom 6061 billet aluminum mounting brackets at our Riverside, CA facility. That reinforced subframe is included in the kit — it’s the only way to run our subcage properly.

The Impaktech subcage arms are fully adjustable so you can fine‑tune angle and position to match your riding style, scrape point, or foot placement needs. Replaceable Delrin puck end caps take the hit in drops and low‑speed tip‑overs, helping protect the bike and saving you money down the road. When they wear, just grab new pucks on Impaktech.com and bolt them on.

Made in the USA. Built to take abuse. Tuned for riders who push electric moto progression.
