DescriptionThe whole story▼
Lining up three or four wide at a local motocross gate puts a 150 SX hard against the wheel ruts and roost thrown up by every bike alongside it, and a fair share of that thrown dirt arcs straight toward the rear sprocket before the pack even reaches the first turn. Accossato lists the GCM1 for the 150 SX built from 2010 to 2020, a chain guide fitted ahead of the sprocket to keep the chain running where it should through exactly that kind of start.
Key Features
- Chain guide for the KTM 150 SX, 2010 to 2020
- Accossato code GCM1, mounts ahead of the rear sprocket
- Keeps the chain tracking on line rather than drifting off the sprocket teeth
- Orange, blue or black
- Same part also listed for the Husqvarna FC 450 and the KTM 125 EXC
- Accossato also lists swingarm sliders and axle blocks for this bike under GPM1, GSM1, RCM1 and RTM1
- No German ABE on file; built for off-road and competition riding
Construction and Material Quality
Accossato shapes the GCM1 specifically for the 150 SX swingarm rather than offering one guide bent to fit several frames, so it locates ahead of the sprocket in the position this bike actually needs. The three available finishes, orange, blue and black, are there for owners to pick whichever sits closest to the rest of the bike's plastics. A guide that has taken a solid hit and no longer sits flush against the sprocket is worth pulling off and checking before the next ride, the same as any other wear part near the chain.
Racing Wheel to Wheel at the Gate
A packed 150 SX gate is one of the harder tests a chain guide faces all season, because the dirt in the air at the start does not only come from the rider's own rear wheel; it comes from every bike alongside, thrown forward at odd angles as the whole row fights for the same line into turn one. Some of that debris lands on the sprocket area whether the rider chose a clean line or not, and a guide ahead of the sprocket gives the chain a defined path to hold even while dirt is still falling around it. Riders who race regularly in a full gate tend to check this area more often than trail riders do, simply because the exposure happens every single moto rather than once in a while.
Fitment and Compatibility
The 150 SX sits on Accossato's application list across the full 2010-to-2020 run for the GCM1, a span wide enough to cover more than one generation of the bike, so matching the exact year against that list before ordering is worth the extra minute. A shared platform underneath a string of Husqvarna four-strokes, including the FC 450 and the FE 350, means the same guide carries over to those bikes too, along with the smaller KTM 125 EXC. Riders who also own one of those models, or who buy a bike from that family later, can fit the identical part without hunting down a second code. For the 150 SX itself, Accossato rounds out the chain line with the GPM1 swingarm slider, the GSM1 floating slider and a choice of RCM1 or RTM1 axle blocks.
Road Approval
No German ABE is on file for the GCM1, so Accossato lists it for off-road and competition use rather than for a bike ridden on public roads.
