DescriptionThe whole story▼
Every riding instructor comes back to the same point: at walking pace, the rear brake is the control that keeps a motorcycle steady. On an Aprilia RS4 125 that lesson is put into practice in car parks and side streets long before anyone worries about the front. Accossato's AGPA221 is a rear pad listed for the RS4 125 across a long run of years, from 2011 to 2020, and this product is the Organic version, the mixture the company describes as long-lasting and gentle on the disc.
Key Features
- Rear brake pads for the Aprilia RS4 125, listed by Accossato from 2011 to 2020
- Organic compound, drawn up for a long working life and a disc that lasts
- Well suited to the slow-speed work the rear brake actually does on the road
- The same shape is also offered in the ceramic racing mixture
- Two pads in the box, which is one caliper's set
- Further rear pads for this model: the AGPA82 and the AGPA258
- No German ABE on record; supplied for competition use
Construction and Material Quality
Accossato's case for this material rests on endurance rather than on drama: it goes on delivering for a long time, and it does not eat into the disc while doing so. At the back of a small motorcycle that suits the pattern of use exactly. The rear pads of an RS4 125 are pressed lightly and often, they seldom get hot, and they may well stay in the caliper for several seasons before anyone thinks about them. The AGPA221 is formed to the outline of that rear caliper and is designed to slide in its guides, which is what keeps a rear brake from binding as it ages.
The Pedal Your Instructor Keeps Mentioning
Slow-speed exercises all come down to the same technique: a steady trickle of drive, a slipping clutch and a light, constant pressure on the rear pedal. Tighten that combination and the bike walks round a full-lock turn without wobbling. Take the pedal away and the whole thing becomes a series of lurches. The same technique earns its keep long after the training ground, whenever an RS4 125 has to be turned round in a narrow lane or held on a slope in a queue. Because that use is gentle, riders forget the rear pads exist until the pedal starts feeling odd. Make a habit of looking into the caliper when the chain is being adjusted, and press the pedal several times after any pad change so it comes up firm before you set off.
Fitment and Compatibility
Accossato's application list gives the AGPA221 for the RS-4 125 with a span of 2011 to 2020. The catalogue also holds the AGPA82 and the AGPA258 as rear pads for this model, each with its own years, so compare the set in your caliper with what you intend to order. Front pads for the same bike are the AGPA32 and the AGPA142.
Road Approval
No German ABE and no test mark are on file here for the AGPA221, which means we can only supply it for racing and closed-course riding.
Scope of Delivery
One box with two Organic rear pads, the pair a single caliper takes.
