Seat – like I said, it’s ok for 80 -100 miles but after that you might want a break. An air hawk or gel seat will help.
Tyres give 8k and 5/6k depending on the compound. I found PR2’s good and the Roadsmarts seem to be well up to the task as well. They do take a bit of a beating and if they aren’t at the right pressure will wear badly and you will be able to tell immediately. Ensure they have metal caps with a rubber seal or fast riding can see pressure lost over a couple of days.
A Scott-oiler is a great investment. I have the touring mod with the reservoir behind the number plate. It is more than worth it and my chain with 22K varied miles on it in most conditions is still good for more.
Other things to consider are hand guards, even with the fairing your hands are exposed. I have seen some for motocross bikes for about £20 but haven’t got round to fitting them, mostly because I have barely been able to use the bike in the winter months. I can’t bring myself to put a pair of heated grips on it. I have stomp grips on the tank as they give great grip and stop the inside thigh getting cold in the winter.
The brakes like all Yamahas need to be maintained , not strip/ grease every month but dash of cleaning spray. The pipes are going to discolour whatever you do. I try and get oil changed every 4k. This can easily be done yourself. Coolant needs to be topped up because it does heat up quite fast in the summer.
And lastly, the 2007 bikes seem to have frames with slight weaknesses. Case in point being I dropped my bike last year on its side after getting new tyres in the pi**ing rain. The back just spun up and I had no choice in what happened then. The bike went down onto the crash bung and I later discovered a crack in the welding on the right hand side. A little digging on forums revealed this seemed to be a design/manufacturing issue and Yamaha(bless their little hearts) replaced my entire frame even though it was out of warranty, Gratis. The new frame is a revised item and the welding is different.
There are 2 unofficial clubs for Fazers
The UK one is http://fazerowners.yuku.com/directory and has an area dedicated to the litre versions both Gen 1 & 2. There is plenty of helpful tips on all things biking and you can get a foc-u (Fazer Owners Club UK) t-shirt for a tenner.
The US one is dedicated to the Gen2 http://fazerowners.yuku.com/directory but you need to sign in to see pictures etc.
