DescriptionThe whole story▼

A 250 SX-F that gets wheeled straight into the back of a van after every ride, rather than given even a quick look over, tends to build up swingarm wear that only becomes obvious once the chain starts rattling more than it used to. Accossato builds the GPM1 for the 250 SX-F from 2011 to 2015, a slider fitted along the swingarm so the chain runs across a surface meant to wear in place of the arm itself.

Key Features

  • Swingarm chain slider for the KTM 250 SX-F, 2011 to 2015
  • Accossato code GPM1, fitted along the top of the swingarm
  • Chain runs over the slider rather than the bare swingarm
  • Orange, blue or black
  • Also listed for a wide run of Husqvarna four-strokes sharing this swingarm
  • Pairs with Accossato's GCM1 chain guide and GSM1 floating slider for this bike
  • No German ABE on file; for off-road and competition use

Construction and Material Quality

The GPM1 runs the length of swingarm the chain actually crosses on the 250 SX-F, shaped to that specific run rather than cut to a generic length. Taking the ongoing wear so the swingarm itself does not have to is the entire point of the part, and Accossato offers it in orange, blue or black to suit the rest of the bike. A slider worn thin enough to feel the chain through it is overdue for replacing.

What Gets Missed Without a Proper Look

Riders who load the bike up and leave straight after a session, rather than giving the chain and swingarm even a quick glance, are the ones most likely to be surprised by how far a slider has worn by the time someone finally looks closely. A chain rattling louder than it used to, or visibly slack where it was not before, is often the first sign that the slider underneath has worn through further than expected. Building in a two-minute check after loading the bike, rather than skipping straight to packing up and leaving, catches this kind of wear while it is still a simple part swap rather than something that has already started marking the swingarm.

Fitment and Compatibility

Accossato's figures for the GPM1 on the 250 SX-F run from 2011 to 2015, a shorter window than the chain guide listed for the same bike. The slider also carries over to a group of Husqvarna four-strokes on the related platform. Given that narrower window, checking the actual frame year against the list is worth doing, whether ordering this slider on its own or alongside the GCM1 guide and either axle block for the same bike.

Road Approval

Accossato has no German ABE on file for the GPM1, so the slider is intended for off-road and competition riding rather than for use on public roads.
