I have been trying to get the time / distance settings reduced for ages as the default settings result in the indicators flashing too long before self cancelling.
At last I have found a dealer who actually knew how to make this adjustment - Well done Cotswold Motorrad in Cheltenham

The minimum setting is the greater of 300 metres or 10 seconds which works out much better than the default. Just a pity this is not available via the setup menu.
