DescriptionThe whole story▼
A rider still new to working on their own bike often finds the axle blocks one of the more confusing jobs on a 250 SX, mostly because getting the tension even on both sides takes a bit of practice before it becomes second nature. Accossato's RCM1 covers the 250 SX built from 2000 to 2018, a pair of rear axle blocks with their own adjusting screw, built to make that particular job more straightforward to get right.
Key Features
- Rear axle blocks for the KTM 250 SX, 2000 to 2018
- Accossato code RCM1, supplied as a pair, left and right
- Each block carries its own adjusting screw for chain tension
- Orange, black or silver
- Also listed for a wide run of Husqvarna four-strokes sharing this swingarm
- Accossato's RTM1 covers the same bike without the adjusting screw
- No German ABE on file; built for off-road and competition use
Construction and Material Quality
Each RCM1 block takes the place of the stock part at the swingarm end, with a screw built into its own body so chain tension is set from the same point on both sides. Orange, black or silver make up the available finishes, picked by most owners to suit the rest of the bike. A block that no longer sits flush, or shows a visible crack along its edge, is worth replacing rather than left on the bike out of convenience.
Learning to Set Up a Chain Properly
Getting chain tension right on a 250 SX is one of those jobs that looks simple written down and turns out fiddlier in practice, mainly because both sides need the same number of turns to keep the rear wheel pointing straight rather than drifting off at an angle. A built-in adjusting screw removes some of the guesswork for someone still learning, since each turn moves the block by a known amount rather than relying on levering the axle by feel. Riders who practise this job a few times on their own bike, checking the result by eye and by riding it afterward, tend to pick it up quickly once they have a part that makes the adjustment itself straightforward.
Fitment and Compatibility
Accossato's list for the RCM1 spans the 250 SX from 2000 to 2018, a long enough run that checking the exact frame year is worth doing before ordering. A string of Husqvarna four-strokes built on this swingarm takes the identical pair. Riders who would rather adjust the chain the stock way can fit Accossato's RTM1 instead, mounted in the same position.
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.
Scope of Delivery
This listing covers one pair of rear axle blocks, left and right, in the colour you choose.
