The last of those jobs happens at the axle blocks, where the rear wheel's position along the swingarm sets how tight the chain runs and whether the wheel tracks straight behind the front. Accossato's RCM1 covers the EXC-F built between 2000 and 2018, a pair of rear axle blocks with their own adjusting screw built in.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRear axle blocks for the KTM 450 EXC-F, 2000 to 2018\u003c\/li\u003e\n\u003cli\u003eAccossato code RCM1, one pair, left and right\u003c\/li\u003e\n\u003cli\u003eEach block carries its own adjusting screw for setting chain tension\u003c\/li\u003e\n\u003cli\u003eOrange, black or silver\u003c\/li\u003e\n\u003cli\u003eAlso listed for a wide run of Husqvarna four-strokes sharing this swingarm\u003c\/li\u003e\n\u003cli\u003eAccossato's RTM1 covers the same bike without the adjusting screw, for riders who prefer the stock method\u003c\/li\u003e\n\u003cli\u003eNo German ABE on file; built for off-road and competition use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eThe RCM1 pair sits at the ends of the swingarm, in the slots the stock axle blocks occupy, and each one has an adjusting screw worked into its body so the rear wheel can be pushed back and forth without reaching for a separate tool to lever it into place. Both blocks come in the same finish, offered in orange, black or silver, which is worth matching to the swingarm or to the rest of the bike's colours since the blocks sit in plain view once the chain guard is off. Checking that the adjusting screw still turns smoothly, rather than assuming it always will, is worth doing at each service alongside the rest of the chain.\u003c\/p\u003e\n\u003ch2\u003eSetting Up Before the First Ride\u003c\/h2\u003e\n\u003cp\u003eChain tension that was correct in November rarely still is in March, after a winter of storage has let the chain settle, and an axle block with its own adjusting screw turns that job from guesswork into something repeatable. Loosen the axle nut, turn each screw the same number of turns on both sides, and the wheel moves back evenly rather than crabbing to one side as it would if only one block were adjusted. That evenness matters as much as the tension itself: adjusting the two sides unevenly leaves the rear wheel pointing slightly off the frame's centreline, which is exactly the kind of fault a rider notices as a bike that feels a touch sideways under power long before anyone traces it back to the axle blocks. Doing this properly once at the start of the season, and rechecking it after the first few rides bed the chain in, saves having to chase the same problem all year.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eAccossato lists the RCM1 for the EXC-F 450 across 2000 to 2018 on its own application list, and the identical pair also fits a long run of Husqvarna four-strokes built on the same swingarm, among them the FE 450 and the TE 250. Comparing your own frame against the application list is worth doing regardless, since the listed years span many seasons of the bike. Owners who prefer adjusting the chain the stock way, without a built-in screw, can fit Accossato's RTM1 instead; both pairs mount in exactly the same position on this bike.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eNo 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.\u003c\/p\u003e\n\u003ch2\u003eScope of Delivery\u003c\/h2\u003e\n\u003cp\u003eThis listing covers one pair of rear axle blocks, left and right, in the colour you choose.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Off-road rear axle blocks with adjusting screw\u003c\/li\u003e\n\u003cli\u003ePart number: RCM1\u003c\/li\u003e\n\u003cli\u003eColours: Black, silver, orange\u003c\/li\u003e\n\u003cli\u003eUse: Off-road (enduro, motocross)\u003c\/li\u003e\n\u003cli\u003eFitment: KTM 450EXC-F (2000–2018)\u003c\/li\u003e\n\u003cli\u003eCheck: Compare with the application list before ordering\u003c\/li\u003e\n\u003cli\u003eRoad approval: None documented, off-road and competition use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Accossato","offers":[{"title":"Black","offer_id":53856618873098,"sku":"RCM1N","price":77.11,"currency_code":"EUR","in_stock":true},{"title":"Silver","offer_id":53856618905866,"sku":"RCM1T","price":77.11,"currency_code":"EUR","in_stock":true},{"title":"Orange","offer_id":53856618938634,"sku":"RCM1A","price":77.11,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RCM1_black.png?v=1791144430","url":"https:\/\/inter-pace.com\/products\/accossato-offroad-rear-axle-blocks-with-adjusting-screw-ktm-450exc-f-2000-2018-rcm1","provider":"Inter-Pace","version":"1.0","type":"link"}
