DescriptionThe whole story▼

KTM's 125 EXC has stayed in the line-up for years as the smallest of its enduro two-strokes, a bike many riders cut their teeth on before moving to something bigger. Accossato lists the GCM1 chain guide for the 125 EXC built between 2012 and 2020, mounted ahead of the rear sprocket to hold the chain on a steady line regardless of how technical the trail gets.

Key Features

  • Chain guide for the KTM 125 EXC, 2012 to 2020
  • Accossato code GCM1, mounted ahead of the rear sprocket
  • Keeps the chain running on a steady line through technical ground
  • Available in orange, blue or black
  • Same part also listed for the Husqvarna TE 250, the Husqvarna FE 250 and the KTM 125 SX
  • Accossato also offers a swingarm slider, a floating slider and both styles of axle block for this bike
  • No German ABE on file; built for off-road and competition riding

Construction and Material Quality

Accossato's GCM1 is shaped around the 125 EXC's own swingarm rather than stretched from a design meant for several bikes, sitting ahead of the sprocket exactly where this chassis needs it. The colour, orange, blue or black, is a matter of preference only, with the guide working identically whichever is chosen. A guide that has taken a hard enough hit to look visibly out of position should be pulled and examined rather than trusted by eye for the next ride.

A Long-Running Model With a Long Production Run

Few bikes in this part of KTM's range have stayed in production across as many years as the 125 EXC, and Accossato's GCM1 application list reflects that, covering nearly a decade of the bike with the one part. For an owner buying a used example without knowing its exact history, that long production run means the guide is almost certainly still available and correctly sized, rather than being an obscure fit for a single short-lived model year. It also means riders running an older 125 EXC alongside a newer one have the option of a single guide design across both machines. Checking the exact model year against the application list is still the first step, since minor swingarm changes across a run this long are always possible even when Accossato lists one part for the whole span.

Fitment and Compatibility

Accossato's own list runs the 125 EXC from 2012 through 2020 for the GCM1. The same guide also covers a long run of Husqvarna's off-road range sharing this platform, including the TE 250 and the FE 250, plus the KTM 125 SX. A full chain-line set for this bike includes the GPM1 and GSM1 sliders and either style of axle block, all listed under this same model. Matching the bike's exact build year to Accossato's list remains worth doing before ordering.

Road Approval

No German ABE is on file for the GCM1, so Accossato lists it for off-road and competition use rather than for use on public roads.
