Very good horn & very loud. Reasonably straightforward to fit (if using additional mount) & seems good quality. This was fitted to a 2024 BMW r1250 r , & I also purchased the horn mount kit ( item 772964) , note that the mount has been superseded from what's shown on the website & intended for a 1250 GS, but this fitted my bike perfectly. The compressor part is mounted behind the left hand side cylinder & the horn part is attached to the left side clutch cover with the 2 bolts supplied & then the compressor pipe neatly routed between the two. I also purchased the Denali can smart system ( 2368523) which is literally plug + play , & means the original loom remains untouched.
