    Default noise management for DF50

    I would like to reduce the noise at cruising speed on my 2007 Suzuki DF50.

    Does anyone know if there is enough clearance under the cowl to add a layer of sound isolation panels?

    Thanks

    63 Hz 89.1
    125 Hz 93.9
    250 Hz 92.0
    500 Hz 87.0
    1000 Hz 81.7
    2000 Hz 71.5
    4000 Hz 66.3
    8000 Hz 61.9
    dBA 88.4
