Model Significance

The AMP Research B4 represents a defining milestone in full-suspension mountain bike history, engineered by the technical visionary Horst Leitner. This platform is built around AMP Research's brilliant four-bar linkage suspension layout (featuring the iconic Horst-link), which is specifically developed to isolate drivetrain torque and braking forces from the rear shock movement. Constructed from premium thin-walled aluminum tubing combined with precision CNC-machined yokes and pivots, this chassis minimizes overall frame mass to deliver top-tier cross-country (XC) performance.

Decal Set Features

The visual styling strictly follows the brand's clean, industrial identity. The core of the kit consists of the prominent AMP RESEARCH logotypes with a solid white fill and a sharp black outline. The package incorporates the model-specific B4 identifiers embedded within black oval backgrounds, independent oval AMP RESEARCH headtube logos, and rectangular American flag transfers carrying the corporate origin and patent texts across both black and white background variations (PAT# 5,462,302 and MADE IN U.S.A. Pat# 5,509,679).
