โLoud pipes save livesโ. Weโve all heard it, but Iโm not totally convinced. Besides the Euro4-induced purr of most bikes now, if you have got a loud can, you need to be pretty antisocial with it to be heard in cities by cocooned car and lorry drivers.

The Sound Bombโs been around for a while, and while R&G also supply Denaliโs new, smaller version (producing 113dB), itโs the โbigโ one that pumps out 120dB. By splitting the originalโs compressor and sounder, itโs now easier to squeeze the Sound Bomb into tight spaces. I have the compressor behind the fairing on my Versys 650, and the horn down by the bottom of the radiator.
Fitting is relatively simple if youโre happy with electrics, and a separate wiring harness is available for ยฃ10.99. A relay comes with the horn, as it draws a hefty 20A in use, but you wonโt need to press it for long โ a quick blip ensures youโre noticed if things look like theyโre going pear-shaped even in the busiest parts of Londonโs city centre.
Thereโs no real lag or wait for the pressure to build โ Iโd say itโs hardly noticeable compared to the delay you get with CAN bus-equipped bikes. Itโs also still possible to do a light flick, though not quite as easy as with a standard (and much quieter) horn fitted to a bike with traditional wiring.
Combined with my Denali D2 spot lights, I feel confident that other road users are well aware of my presence โย I donโt need to use the Sound Bomb that much, but when I do, itโs extraordinarily effective!
