DescriptionThe whole story▼
Built to outlast the factory sensor on your Ducati Panigale V4, the FSS Fast Shift Sensor from MCT Lohmann — distributed exclusively through TGP MotoRacing — is engineered from the ground up with a stainless steel V2A push rod and bronze bush, materials chosen precisely because they maintain their integrity under the sustained heat loads that routinely defeat OEM quickshifter sensors. At just 14 mm wide and approximately 20 g, the CNC-machined housing is a study in purpose-built racing precision.
Key Features
- Stainless steel V2A push rod with bronze bush — far more durable than original Ducati sensors, and fully serviceable after a crash
- Absolute heat resistance means the sensor remains reliable even at extreme engine temperatures where OEM units fail
- Micro-fine sensitivity for consistently clean, precise gear changes in both road and track conditions
- Shift direction freely selectable — tension or compression — with two matching connection cables included in the box
- Output signal configurable as normally open or normally closed (open collector), with a re-programmable Hall sensor for maximum flexibility
- Pre-tensioned travel of ± 3 mm / up to ± 25 kg for precise actuation feel
- Fully dismantleable construction — can typically be repaired rather than replaced following an incident
Materials and Build Quality
The FSS is where material selection becomes a competitive advantage. The V2A stainless steel push rod resists corrosion and fatigue far beyond what mild steel or alloy alternatives can offer, while the paired bronze bush provides the controlled, low-friction sliding action needed for repeatable Hall sensor triggering. The CNC-machined aluminium housing keeps the assembly to around 20 g without compromising rigidity — critical on a motorcycle where every component in the shift linkage contributes to the feel of the gear change.
Because the unit is fully dismantleable, a minor crash that bends a push rod is a repair job rather than a write-off. Replacement push rods and bushes can be fitted, making the FSS a genuinely long-term investment compared with sealed OEM sensors.
Performance on Road and Track
The re-programmable Hall sensor at the heart of the FSS allows the output to be set as a normally open or normally closed signal, meaning it integrates with the Panigale V4's existing quickshifter input without any signal-polarity compromise. Pre-tensioned spring travel of ± 3 mm and up to ± 25 kg actuation force gives the system the mechanical authority to reject false triggers from vibration while remaining responsive to genuine shift inputs — the balance that separates a race-grade sensor from a budget accessory. Part number FSS-DUV4 connects via M6 external / M6 internal threads as standard.
Fitment and Compatibility
The FSS Fast Shift Sensor (part number FSS-DUV4) is designed specifically for the following models:
- Ducati Panigale V4 (2018–2024)
- Ducati Panigale V4S (2018–2024)
