Bitubo XXT6 Rear Monoshock for 2020+ Aprilia RS/TUONO - A0050XXT61

The Bitubo XXT6 Rear Monoshock, part number A0050XXT61, is a rear-suspension replacement and upgrade for 2020+ Aprilia RS/TUONO. The setup combines spring preload, rebound, compression, length adjustment. It replaces aging factory damping with a purpose-built Bitubo component while adding the adjustment range specified for this exact part. That gives you a more useful setup window for matching the chassis to rider weight, load, and intended use instead of being locked into a one-setting stock suspension package.

About Bitubo XXT6 Racing Series:

The Bitubo XXT platform is a race-focused rear monoshock derived from the higher-spec XXZ program, using an external reservoir and a fully adjustable damping package. The XXT6 configuration combines manual spring preload with compression, rebound, and reduced-length geometry for riders who want a precise, track-oriented rear setup.
