CBR125 2007 general parts help

[definetlynotw...]

Hello, I have recently bought myself 2007 CBR125 with 18,000 miles on the clock. I can't yet drive it until October and until then I would like to do little fixes on it.

I would like to ask about general service parts for it, what oil, what spark plug, air filters, chain and sprockets you people out here suggest to use and where about can I get them (price does not matter, I am not wanting to go cheap on the bike).

Thank you, stay safe.

Buy the Haynes manual?

Edit: There's a "Sportsbikeshop" in Leeds, which should have service parts. Use their parts/prices for internet searches for other suppliers. Wemoto, Demon Tweaks, Fowler's, Motorcycleparts, eBay (care!) etc, etc. I would be inclined to keep your bike bog standard and not eff about with it!
