Make the motorcycle cover out of silnylon or DWR nylon - light and packs small.

or less weight but less water proof https://ukfabricsonline.com/2oz-pu-nylon
Note that having the number plate visible is probably only a requirement in Europe, anywhere else and you can cover the entire thing.

No need for a torch .. use the head lamp.

...................
Weight this stuff up... the mole bags weight a ton.

Ditch the sandals - weight + bulk... aqua shoes will do - light and bunch up into nothing.

NO JEANS! - they are a pain to wash and take forever to dry. Get some pants that the lowers zip off - they will be light weight and are both pants and shorts -hiking shops have them .. they are not cheap but willlast longer than jeans will. Some thermal pants/long johns under these make for cold weather pants too.

Cutlery set - no. You already have a knife .. you only then need a spoon. No fork.

No knife sharpener .. the blade should keep for a year before requiring sharpening. You will be meeting HU communities along the way - they will have knife sharpeners and other things. Take what you need, not what you might possibly need to keep yourself comfortable.
---------------------
As shu says .. try to eliminate things that you already have something else that will do that job.

Take all the stuff and weight it individually and put it on a spread sheet. Then you can go through it and target the heavy stuff .. and then the stuff that can be substituted by something you already have.

You will get there. And it is a compromise... if you really really need something ... buy it along the way - it becomes a souvenir.

Be thoughtfull of leaving the bike with its luggage .. you want something to take off the bike that contains the important stuff - photos! id, money, camera, garmin inreach etc. I usually do this with a small tank bag. Call it a hand bag if you like.
