DescriptionThe whole story▼

The 125 SX has carried the same basic rear axle-block layout across a production run stretching from 2000 to 2018, and Accossato's RCM1 covers that whole span with a pair fitted at each end of the swingarm, a built-in screw on each side setting chain tension in fine, even steps.

Key Features

  • Rear axle blocks for the KTM 125 SX, 2000 to 2018
  • Accossato code RCM1, fitted at each end of the swingarm
  • Built-in adjusting screw for setting chain tension
  • Available in orange, black or silver
  • Same part also listed for the Husqvarna TE 125, the Husqvarna TE 250 and the Husqvarna TE 300
  • Accossato also offers a chain guide, two styles of swingarm slider and the screw-free version of this block for this bike
  • No German ABE on file; built for off-road and competition riding

Construction and Material Quality

Accossato sizes the RCM1 to the 125 SX's own axle diameter and swingarm slot, building the screw into the block as one piece rather than adding it separately. Orange, black and silver are offered purely as a colour choice, with the screw setting the wheel's position the same way in each. A block whose screw binds, or whose face carries a deep gouge from an impact, deserves close inspection before being trusted again.

Sprocket Changes for Every Track

Club racers who travel between different motocross tracks often carry a selection of sprockets to suit tighter or more open layouts, swapping gearing more often than a rider sticking to one local circuit ever would. Each sprocket change shifts how much chain slack is needed, and the RCM1's built-in screw turns that reset into a quick, repeatable job rather than a fresh guess every time, with both sides moved the same number of turns to keep the wheel square. Riders who change gearing this frequently tend to notice the difference a built-in screw makes most, simply because they are doing the job far more often than someone who sets tension once at the start of a season and leaves it there.

Fitment and Compatibility

Accossato covers the 125 SX from 2000 right through to 2018 on the RCM1's own list. That identical screw-equipped pair is shared with three Husqvarna enduros built on this swingarm: the TE 125, TE 250 and TE 300. An owner leaning toward the stock, no-screw method instead can switch to the RTM1 without any change in fitment, since it bolts into the same slot. Whichever is chosen, matching the 125 SX's real build year against the list is the sensible first step.

Road Approval

No German ABE is on file for the RCM1, so Accossato lists it for off-road and competition use rather than for use on public roads.
