DescriptionThe whole story▼
A WR250F taken out on a long trail ride rarely has a mechanic within easy reach if something needs adjusting halfway through the day, so chain tension is worth getting right before setting off rather than hoping to fix it later on the trail. Accossato's RCY1 fits that need on the WR250F built between 2009 and 2018, a pair of rear axle blocks with their own adjusting screw for a quick, repeatable check before heading out.
Key Features
- Rear axle blocks for the Yamaha WR250F, 2009 to 2018
- Accossato code RCY1, 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 Suzuki RM-Z 250, Suzuki RM-Z 450, Yamaha YZ125 and Yamaha YZ250
- No German ABE on file; built for off-road and competition use
Construction and Material Quality
The RCY1 block mounts where the stock part sits at the swingarm end, with its own screw for setting tension from that single point rather than levering the axle by hand. Blue, black and silver cover the finishes on offer, blue matching the WR250F's own factory look closely. A block that no longer sits flush, or shows a visible crack, is worth replacing before the next ride.
No Mechanic Waiting on the Trail
Trail riding on a WR250F usually means being well away from any workshop for hours at a stretch, so any check worth doing wants doing properly before leaving rather than left for later, when the only tools available are whatever fits in a tank bag. An adjusting screw built into each axle block turns chain tension from a job needing the bike on a stand into something that can be checked and corrected in the driveway in a few minutes. Riders who do their own pre-ride checks appreciate not needing to lever the axle by feel before a long day out.
Fitment and Compatibility
Accossato's list covers the WR250F from 2009 to 2018 for the RCY1, and the identical block also fits the Suzuki RM-Z 250 and RM-Z 450, plus the Yamaha YZ125 and YZ250. Checking the exact frame year against that list before ordering is worth doing regardless of how widely the part is shared.
Road Approval
Accossato lists no German ABE for the RCY1, so the blocks are intended 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.
