DescriptionThe whole story▼
The JP ES 004 replaces the RSV4's rear light in the circuit so nothing is reported once the tail unit is removed.
Key Features
- Aprilia RSV4 (2021–2024)
- Replaces the rear light in the circuit
- No bulb failure warning on the panel
- Plugs into Aprilia's own connector
- Needed once the tail unit comes off
- Standard light refits at any time
What Happens Without It
The controller watches the rear lighting circuit and treats an absent assembly as a failed bulb. The warning stays on the panel until the circuit is satisfied.
Race Bodywork
An RSV4 prepared for a circuit gets a one-piece race tail with no provision for lights. It is among the first changes on any serious build.
A Load, Correctly Presented
The eliminator gives the circuit what it expects. Nothing is masked and nothing waits in memory for the next diagnostic session.
The Airbox Inside the Frame
Aprilia routes the intake through the twin spars, fed by ducts in the fairing nose. It is one reason the motorcycle is as narrow as it is.
A MotoGP Programme Behind It
Aprilia races a V4 at the highest level and the road bike benefits from the aerodynamic and electronics work in ways that are easy to see.
Scrutineering
A warning lamp on the panel reads as an unresolved fault whatever caused it. Satisfying the circuit properly avoids an argument at the gate.
Plugged In
Aprilia's own connector with no adapters. It takes minutes while the tail unit is already off the bike.
Nothing Spliced
The loom stays exactly as the factory built it, which protects the value of a motorcycle that will be sold on eventually.
Reversible
The standard light and tail unit refit at any time.
Track Only
Removing rear lighting ends road legality across Europe.
An Adjustable Chassis
Headstock angle, swingarm pivot height and engine position can all be moved on an RSV4, which is close to unheard of on a road motorcycle. It is a race chassis that happens to be sold with lights on it, and preparing one is mostly a matter of taking those off.
