DescriptionThe whole story▼
Accossato splits its YZ250F axle blocks into a newer code than the one used on the brand's older models, since the RCY3 covers a tighter, more recent window on this bike than codes like the RCY1 cover elsewhere in the range. Built between 2014 and 2018, the RCY3 is a pair of rear axle blocks with their own adjusting screw for the YZ250F.
Key Features
- Rear axle blocks for the Yamaha YZ250F, 2014 to 2018
- Accossato code RCY3, supplied as a pair, left and right
- Each block carries its own adjusting screw for chain tension
- Blue, black or silver
- Same pair also listed for the Yamaha YZ450F
- Accossato's RTY3 covers the same bike without the adjusting screw
- No German ABE on file; built for off-road and competition use
Construction and Material Quality
What sets the RCY3 apart from a stock block is the screw worked into its own body, letting tension be set from that single point rather than by levering the wheel back into place. The pair comes in blue, black or silver, blue being the pick that sits closest to the YZ250F's factory finish. Once either block shows a crack or has worn out of true, swapping the pair is the sensible course rather than running it further.
A Newer Part Number for a Newer Bike
Owners used to the older RCY1 code from a previous YZ250F, or from a different bike in the range entirely, should note that the newer, narrower-build YZ250F takes the RCY3 instead, a separate part number rather than an updated version of the same one. That distinction matters when ordering, since the two codes are not interchangeable even though they do the same job. Confirming which code applies to a given bike's build year avoids ending up with the wrong pair on the bench.
Fitment and Compatibility
Accossato's own list runs the RCY3 against the YZ250F from 2014 to 2018, and the identical pair also fits the Yamaha YZ450F. Checking the exact frame year against that list is worth doing before ordering, given how much narrower this window is than some other chain parts in the range. Riders who prefer the stock method of chain adjustment can fit the RTY3 instead, in the same position.
Road Approval
No German ABE is on file for the RCY3, so Accossato lists it for off-road and competition use rather than for use on public roads.
