@Zinji, welcome here!
Can you do some light touring on a Kymco Exciting 400i scooter?
The answer is absolutely YES!
Couple of days ago did some touring with two friends of mine here in nordern Italy.
One had a HONDA Africa Twin 1250 with automatic gear the other had a HONDA X-ADV 750 same features.
I drove my trusted XCiting 300R and didn't have any disappointments, neither from speed nor from performance.
Going twice a year to Croatia to tour islands, daily about 300 kms, relaxing on this scoot, with low fuel bill of 3.2 ltrs/100 kms.
Your 400 is even more agile handled right.
