DescriptionThe whole story▼

There is a kind of Sunday riding that never goes near a circuit and still asks a great deal of a motorcycle: a hundred corners of moorland road, a group that pushes a little harder after lunch, and descents where the brakes work almost continuously. A Ducati Monster 821 Dark does that job very well. Accossato's EV1 street/track material is written for riders in exactly that position, and on the AGPA177 front shape it is sold as article AGPA177EV1. The company recommends the compound for street use and for amateur track work. Listed for 2015 and 2016.

Key Features

  • Front pads for the Ducati Monster 821 Dark, 2015 and 2016
  • AGPA177EV1: the AGPA177 shape carrying the EV1 street/track material
  • Accossato names road riding and amateur circuit use in equal measure
  • Aimed at riders who work the front end hard on public roads
  • One caliper per disc, two discs, therefore two boxes to order
  • Two pads inside each box
  • ST, EV2 and ZXC are pressed on the same shape
  • No German ABE provided; sold as a competition part

Construction and Material Quality

What Accossato describes here is a material with two jobs, and the interesting thing is that they are not as far apart as the names suggest. A demanding road descent and a modest track session make similar demands: sustained use, little time to cool, and a rider who wants the lever to stay where it was. Since the AGPA177 plate underneath is identical throughout the family, anyone moving from an everyday compound to this one is changing only what the friction layer does, never how the part sits.

Sunday Roads Ridden at a Serious Pace

Fast road riding punishes brakes in a way that quick riders often underestimate. There are no run-off areas and no marshals, so the front end is used earlier and more often than it would be on a circuit, and it is used from unfamiliar speeds on a surface that changes every few corners. Over a long day the Monster 821 Dark can easily see more braking events than it would in an afternoon of sessions, even if none of them is as severe.

Keep an eye on what that costs. Check the remaining material before a big ride and again afterwards, because a single hard day can take more than a month of commuting. Look at the disc faces for scoring while the wheel is out of the way, keep them free of anything oily, and bring new pads up to temperature gradually over the first miles rather than trusting them on the first steep descent of the day.

Fitment and Compatibility

The application entry for this version runs across 2015 and 2016 only, at the front wheel. Two calipers work that wheel and each one takes a box, making two the sensible quantity. Accossato lists the AGPA42 for the rear of the same two years, and the DKS053 is the disc offered for the machine. Because the AGPA177 shape reaches a good many models in this catalogue, always compare the article number rather than trusting a model name.

Road Approval

No test certificate and no German ABE for the AGPA177EV1 have reached our files, which is why the article is catalogued for racing and closed-course use.

Scope of Delivery

Two AGPA177 pads in the EV1 street/track material, one box, the set for a single front caliper of the Monster 821 Dark.
