DescriptionThe whole story▼
A 150 SX bought second-hand often arrives with no real history of how the previous owner looked after the rear end, and the axle blocks are an easy place for that neglect to hide, tucked behind the chain guard where a quick glance rarely reaches. Accossato's RTM1 replaces those blocks on the 150 SX built between 2009 and 2018, a pair that follows the stock method of setting chain tension rather than adding a screw of its own.
Key Features
- Rear axle blocks for the KTM 150 SX, 2009 to 2018
- Accossato code RTM1, one pair, left and right
- Chain tension set the stock way, with no built-in adjusting screw
- Orange, black or silver
- Also listed for a wide run of Husqvarna four-strokes on this swingarm
- Accossato's RCM1 covers the same bike with an adjusting screw, for riders who prefer that method
- No German ABE on file; built for off-road and competition use
Construction and Material Quality
The RTM1 pair sits in the same slots as the stock axle blocks, holding the rear wheel's position at each end of the swingarm without changing how the chain is tensioned from the way the bike left the factory. Accossato offers the pair in orange, black or silver, a small enough choice that most owners pick whichever shade sits closest to the rest of the bike's plastics. A block that shows a deep scrape or a visible crack is worth replacing as a pair rather than only the one that looks worse.
Buying a Used Bike with No Service History
A 150 SX changing hands privately rarely comes with any record of when the chain was last adjusted properly, and axle blocks that have been nudged unevenly for years tend to leave the rear wheel sitting a touch off the frame's centreline without the new owner ever being told. Pulling the rear wheel on a bike with unknown history and giving both blocks a proper look, rather than trusting whatever setting the previous owner left behind, is one of the more useful first jobs on a bike bought this way. Fitting a fresh pair removes any doubt about hidden wear and gives a known starting point for every adjustment that follows.
Fitment and Compatibility
The application list for the RTM1 covers the same span as its screw-equipped sibling, the 150 SX from 2009 to 2018, and both pairs mount in the identical slot on the swingarm, so the choice between them comes down to adjustment method rather than fitment. Beyond the KTM itself, a number of Husqvarna four-strokes built on this swingarm take the same pair, among them the TE 125 and the FC 350. Whichever version is fitted, comparing the exact build year against Accossato's own list is still worth the few minutes it takes before ordering.
Road Approval
Accossato lists no German ABE for the RTM1, so the blocks are intended for off-road and competition use rather than for use on public roads.
Scope of Delivery
Supplied as one pair of rear axle blocks, left and right, in the colour you choose.
