Purchased this to fit on a 2024 BMW r1250 r which it does perfectly even though it's listed as the GS 1250 only, & note that the part is now different to what's shown on the website. The changed part which holds the horn no longer fits under the headstock but now attaches to the left hand side clutch cover using the 2 bolts supplied, & the compressor bracket fits behind the left side cylinder head again using the supplied bolts.
It makes a nice installation of the horn, comes with comprehensive fitting instructions, appears well made & looks unobtrusive.
As with most Denali products, it's not cheap & that's the reason for deducting one star from the rating, but as an overall purchase I'm very pleased with the fit & finish.
