sip speedo sensor mounting

[Dazza]

Where's the best / easiest/ neatest place to mount the sip speedo sensor? I've just had the sensor and bracket delivered but can't see a suitable mounting point ( front disc fitted)
I've seen a neat bracket to fit on the rear shock mount on the casing that picks up one of the rear wheel nuts but don't fancy drilling the casing there..

i made a bracket out of sheet steel that clamps behind the rear shock lower mounting and hold the sensor alongside the engine shock boss.. if I get a chance I will take a picture..
