DescriptionThe whole story▼
A rear wheel change on a Yamaha YZF-R1, built between 2015 and 2021, usually comes with a chain adjustment in the same breath, and Melotti Racing's Corsa-line rear axle sliders were shaped around that routine rather than against it. The PR.YA.315P gives the rear axle the same one-piece, Ergal-built protection as its front counterpart, built to come off and go back on as part of a normal workshop job, not just after a crash.
Key Features
- Rear wheel axle sliders, Corsa line, for the Yamaha YZF-R1, 2015 to 2021
- Melotti part PR.YA.315P, available in black or natural
- Machined from Ergal, one piece per side
- One slider works as a nut-protector in place of the original axle nut
- Rear nut includes a self-locking feature, a first for aftermarket aluminium axle nuts according to Melotti
- The other slider clamps and turns the axle directly for a fast change
- Front version, the PR.YA.315A, available separately
Construction and Material Quality
Melotti machines the PR.YA.315P in Ergal for the same reason it uses that material on the front sliders: better resistance to abrasion than a plastic guard offers, in a part that still has to come off cleanly for a routine chain adjustment. The rear nut-protector carries a self-locking system that Melotti describes as a first in aftermarket aluminium axle nuts, a detail it added specifically because the rear axle sees that little bit more vibration during normal riding than the front. The second slider's all-in-one clamping lets the axle be gripped and turned directly rather than needing a separate spanner held against a conventional nut.
A Chain Job That Does Not Fight the Protector
Adjusting chain tension on a YZF-R1 means the rear axle comes loose and the wheel shifts in the swingarm slots every time, which is exactly the kind of repeated handling that makes a bolted-on axle protector annoying to work around. Because Melotti's nut-protector replaces the axle nut itself rather than sitting over it, there is nothing extra to remove before the axle can be loosened, and the self-locking feature on the rear nut means a mechanic is not second-guessing whether it has been torqued correctly after every adjustment. It is a detail aimed squarely at the YZF-R1's own workshop routine, not just at a day it falls over.
Fitment and Compatibility
Melotti's fitment window for the PR.YA.315P on the YZF-R1 is 2015 to 2021, which our listing mirrors. A separate part, the PR.YA.315A, covers the front axle and is not bundled with this rear set. The YZF-R6 takes this identical rear slider across its own 2017-to-2021 range. Order black or natural to suit your other chassis parts.
Road Approval
No ABE exists for the PR.YA.315P. It is supplied for racetrack and closed-circuit use, with race organisers applying their own rules on wheel-change procedures at a meeting.
Scope of Delivery
