What stood out immediately isn’t just the GSX750S-inspired aesthetic—it’s the dual-axis geometry of the retractable unit. A simple single-pivot design would have pushed the H7 LED bucket too high, creating significant aerodynamic drag. Instead, they’ve developed a linkage that moves the assembly forward while lifting it at the same time.
I spent some time at the bench measuring actuator arm deflection, and the tolerances are extremely tight—clearly designed to avoid binding. The linear motor is reportedly tested to around 3,000 cycles, and based on feel alone, it comes across as very robust.
They’re also using an Arduino-based control board to manage DRL dimming and the auto-retract sequence. That said, having a microcontroller this close to the radiator’s heat soak area does raise some concerns about long-term thermal stability. I’m currently working on routing the wiring to improve shielding and reduce exposure.
Before final installation, I wanted to ask: for those working with dual-axis linkages exposed to direct wind load at highway speeds, what’s your preferred method to eliminate pivot chatter? Are phosphor bronze shims still the go-to, or have you found a better zero-clearance solution?
