10Ah vs. 14Ah is not critical unless your bike is hard to start. Most important is that the battery gives high current without dropping the voltage too much. Then the bike starts easily.
A well known brand is a good choice, but you can try your luck with Biltema if you are on a budget. I have bought two batteries from them - one is still good after several years, but the other lasted only one year. I guess it depends how long the battery has been shelved before you get it, and maybe the quality is also not consistent.
If the spark plugs are expensive in Norway, as they are here, the cheapest place I could find in Europe was Mister Solutions in UK. Even with shipping a lot cheaper. However, expect to get spam from them if you buy from them. I had to tell them 3 times to stop it before they actually did.
