DescriptionThe whole story▼
Owners who move between a 350 EXC-F and one of the many related KTM or Husqvarna models over the years rarely have to learn a new part number for the floating swingarm slider, since Accossato lists the identical GSM1 across almost the whole family. On this bike it covers 2012 to 2020, mounted so the whole piece can move with the chain rather than being fixed to a single line.
Key Features
- Floating swingarm chain slider for the KTM 350 EXC-F, 2012 to 2020
- Accossato code GSM1, mounted so it can follow the chain's movement
- Orange, blue or black
- Also listed for a wide run of other KTM two-stroke and four-stroke off-road models
- Can be combined with Accossato's GCM1 chain guide and either axle block for this bike
- No German ABE on file; built for off-road and competition use
Construction and Material Quality
A fixed slider stays bolted in one place regardless of what the chain is doing; the GSM1 instead sits in a mount that lets it shift with the chain's own movement, which is the detail the floating name refers to. The same three finishes, orange, blue and black, run across Accossato's range for this bike. A mount with play beyond what feels normal is worth checking at the same time as the chain.
The Same Part Number for Years of Ownership
A rider who has owned a two-stroke from this family, then moved up to a four-stroke enduro bike, then perhaps added a motocross model alongside it, can keep buying the identical GSM1 at every stage rather than relearning a new code each time the garage changes. That continuity makes spares easier to manage for anyone running more than one bike from the range at once, since a slider bought for one machine fits straight onto the next without checking anything beyond the swingarm shape itself.
Fitment and Compatibility
Accossato names the 350 EXC-F across the full 2012-to-2020 run for the GSM1, matching the span given for the chain guide on the same bike. The identical part also appears against a long run of other KTM two-stroke and four-stroke off-road models sharing this swingarm. The GCM1 guide and either axle block round out the remaining chain parts listed for this bike.
Road Approval
Accossato lists no German ABE for the GSM1, so the part is intended for off-road and competition riding rather than public roads.
