Bonamici Racing Race Rearsets with Quick Shifter – Aprilia RSV4 / Factory / R / RR / RF (2009–2016) A004R

Finding the perfect riding position is what separates a good track day from a great one. Bonamici Racing's A004R race rearsets bring millimetre-precise adjustment to the Aprilia RSV4, Factory, R, RR and RF (2009–2016), letting you dial in both the brake lever and gear pedal to exactly where your feet want to be — lap after lap, without fatigue. A quick-shifter rod is included as standard, and the entire assembly bolts on without modification.

Key Features

• Millimetre-precise position adjustment of both the brake lever and gear pedal for a truly personalised, all-day comfortable riding position
• Quick-shifter rod included — enables seamless clutchless upshifts and keeps your focus entirely on the track
• Designed exclusively for reverse shift pattern, delivering a purpose-built solution for track and performance riders
• Integrated return spring in the brake lever ensures consistent, predictable pedal feel and optimised braking response
• Anti-slip footpeg platforms maintain secure boot contact even in the most demanding cornering conditions
• Rubber-tipped gear pedal tip enhances grip and cushions shift inputs for improved comfort during long sessions
• CNC-machined aluminium construction with a black anodised finish for lasting durability and a race-ready aesthetic

Precision Engineering for the Track

Bonamici Racing machines the A004R from high-grade aluminium using CNC milling processes that guarantee exact tolerances across every component. Nothing flexes, nothing plays — each adjustment you set stays set. The black anodising does more than look sharp; it forms a hard protective layer that resists the abrasion, heat and road contamination a track bike is exposed to every session. The result is a rearset system that feels as purposeful on the fiftieth lap as it does on the first.

Integrated Quick-Shifter Compatibility

The A004R is engineered specifically to work with a quick shifter from the outset, not as an afterthought. The included quick-shifter rod integrates cleanly into the assembly, allowing lightning-fast upshifts without clutch input. Lap times tighten, corner exits improve, and the mechanical sympathy between rider and machine increases — which is exactly why this system has become a fixture on RSV4-based track bikes across Europe.

All-Day Ergonomic Comfort

A rearset that can only be set to one position is a rearset that fits nobody perfectly. Bonamici Racing's millimetre-step adjustment means riders of every build — whether you prefer a tucked, aggressive crouch or a slightly more upright stance for endurance events — can find their optimum. The anti-slip platforms lock your boots in place confidently, while the rubber-tipped gear pedal absorbs vibration and reduces foot fatigue over extended stints.
