Been thinking about getting a xena disk lock myself. When the bike is here it lives in the garage and I feel fortunate to have the storage and peace of mind. But if my girlfriend or I go somewhere and need to lock it up for hours on end, the disk lock seems a good choice. As far as I can tell, we'll never need to leave it locked up overnight outside anywhere.
Newbie just make sure you get good insurance with the lowest deductible possible. No sense in having a $500 deductible for a $2700 scooter.
