Modern Vespa

In reverse mode, there's this sound, and it's loud I have not found any way of disabling this in the settings. Will it be possible with future software updates?

Instead on putting in reverse, I reverse the scooter manually before inserting the key. This is harmless to the engine?

Does anyone have a good tip for brake disc lock with alarm?

I bought a Xena XZZ6L disc lock with alarm for my GTS 300. It's a bit of a tight fit but the lock seems very strong.

However, I hate the alarm functionality (there are a lot of negative reviews on websites but I had hoped they would have fixed the problems). The alarm goes off piercingly whenever I take off and put on the lock. It really needs a longer delay before sounding. I don't know why the alarm goes off when I have the key in the lock.

I removed the battery and alarm problems solved! It's still a solid disc lock but no alarm.

I probably should have bought the ABUS Trigger 345 alarm.

The abus 345 will fit in on the disc brake?
Will every disk brake fit? Space between tyre and disc is not so big.

The Abus 345 is designed for small motorbikes and scooters, so it will probably fit. But I don't have one so I can't say for sure. You might have to buy it, try it, and return it if it doesn't fit.
