What's Included
1 × replacement rear brake-disc rotor, as shown in the product photographs. A separate aluminium carrier, mounting bolts and ABS components are not stated as included.
Important Fitment Information
Some early R850R, R1100R and R1100RT cast-wheel versions use this rotor with a separate aluminium mounting carrier. The rotor-only reference does not include the carrier; compare your complete original assembly.
R1100RS is excluded. It uses a different rear-disc reference family; do not confuse it with the later R1150RS listed above.
Check the outer diameter, centre opening, mounting PCD, hole spacing, wheel/hub type, carrier and ABS equipment against the existing part. A dimension or mounting mismatch means this rotor should not be fitted.
Installation
Braking components are safety-critical. Have a competent mechanic inspect the fitment and test the rear brake after installation.
Delivery & Returns
Free UK delivery with an estimated 2–3 working-day service and 30-day returns, as stated in the existing store listing; applicable terms apply.
