10 months no way. You can only have 90 days on a tourist visa.
I suggest you apply to one of the Shenghen signatory countries, that way you will be able to visit 27 countries across Europe but not the UK.
Costs will depend on where you go and you will still need to fly from Iran to your entry country. You will need to find a flight that will allow you to transport your bike as well.
The good news is that camping sites are common throught Europe but I suggest you buy a suitable guide book.
