Lots of places to get service items from, I use Opie Oils for oil and some other fluids, also the likes of Tegiwa, Coxmotorparts etc.
Oil and fluids are personal preferance really, genuine Honda is fine, I always use genuine Honda MTF for gearbox, I've always used Castrol Edge for engine oil with HAMP oil filter although genuine is fine and Motul brake fluid and Motul coolant, I personally have never had any issues using these products.
