DescriptionThe whole story▼
A dropped chain is one of the quieter dangers on a Yamaha YZF-R3, built between 2015 and 2020, running an Öhlins mono-shock: a snapped or jumped chain can whip back and strike the shock reservoir mounted close to the swingarm pivot. Melotti Racing's Öhlins Shock Reservoir Guard sits over that reservoir specifically to take a hit of that kind on this YZF-R3, rather than leaving the reservoir itself exposed.

Construction and Material Quality
The PSM.YA.1141 is machined from solid Delrin, a material Melotti favours for guards exposed to a sudden impact because it absorbs a hard knock without shattering. Its shape is built around the body of an Öhlins mono-shock reservoir as fitted to the YZF-R3, wrapping the vulnerable side facing the chain run while leaving the reservoir's own adjusters reachable. A stainless steel Murray clamp, included in the kit, secures the guard without needing to disturb the shock's own mounting hardware, so fitting it is a job on its own rather than part of a shock removal.
A Guard Built for One Specific Failure
Most reservoir guards in Melotti's range are built around a slide; this one is built around a different, more specific scenario, a chain that has snapped or come off its sprocket and is free to thrash against whatever is nearby, which on a YZF-R3 running an Öhlins shock often means the reservoir sitting close to the swingarm pivot. It is a failure that tends to happen without warning, usually under hard acceleration out of a corner, and a reservoir hit in that way can mean a shock sent away for repair rather than just a scuffed cover. Fitting the PSM.YA.1141 does not prevent a chain failure, but it gives the shock's own reservoir a sacrificial layer in exactly the spot a broken chain is most likely to reach.
Fitment and Compatibility
Melotti lists the PSM.YA.1141 for the Yamaha YZF-R3 built between 2015 and 2020, matching our listing, and it is specific to bikes running the Öhlins mono-shock on this chassis; it is not listed for the Yamaha YZF-R25 in Melotti's range. It is often ordered with the AIS valve cover and brake fluid reservoir guard for the same YZF-R3 as part of one order.
Road Approval
No ABE covers the PSM.YA.1141. It is supplied for racetrack and closed-circuit use, consistent with the kind of chain-failure risk it is built to guard against during competition riding.
