Rear shock FG Gubellini FSM31 for Aprilia Tuono V4 1000 R APRC 11-15

ADJUSTEMENT FEATURES:

- Hydraulic rebound register (40 click)
- Hydraulic compression (40 click)
- Adjustable lenght (9mm)
- Hydraulic spring preload

FG Gubellini FSM31 is a single hydraulic shock absorber with large expansion tank (pressurized by nitrogen) rigidly fixed to the body, dedicated to motorcycles with road, sport and naked characteristics.
Available for numerous motorcycle models including the most recent sports and hypersport models, for each of which a specific calibration has been developed, both in terms of hydraulics and springs. Depending on the weight and driving characteristics, everyone can further customize the basic set-up by replacing the spring with another one with a different resistance.
The hydraulically controlled spring preload via a convenient click knob allows you to adjust the spring preload at any time and without the need for tools, depending on the load conditions and driving style. The knob can be integrated into the body or connected via a flexible tube.
All the details of these suspensions are machined from solid aluminum 7075 (Ergal) or steel. This model combines compactness, highly technological features and an unparalleled quality / price ratio.

The whole range of suspensions produced by FG can be customized on request. At the time of purchase, specify your weight, height, the type of use you make of the bike and the characteristics of your riding. We will design the valves and hydraulic settings that best suit your characteristics. Remember: the best suspension is the one that suits your needs !!!

Technical content:

- Rear shock type FSM31 with 4 external adjuster: lenght (9mm), hydraulic rebound (40 click), hydraulic compression (40 click) and spring initial (hydraulic type).
- 3D design: Each shock absorber is carefully studied using 3D solid modeling software, thus allowing the simulation of performance under stress.
- Piston with calibrated band: The pistons of the rear shock absorbers are hot calibrated. thanks to this procedure it is possible to maintain optimal performance even after thousands of km of use. Furthermore, when the shock absorber overheats the calibrations do not decay.
- Processing: All the details that make up the suspensions are made using cutting-edge machining centers with strictly controlled materials.

- Modular system: The mono FSM11 and FSM31 are made using a modular system that allows installation on all motorcycles. Through this system, FG Gubellini uses the same structure for many motorcycle models, thus guaranteeing production continuity.
- Oversized tank: The oversized nitrogen tank guarantees better performance than smaller tanks. Furthermore, when the shock absorber heats up, the greater volume guarantees a lower increase in internal pressure.
