Welcome to the forums and to the mighty FZ6.
Of the dozen, or so, bikes I have owned, the FZ6 is my favourite!
As for tyres, Metzeler Z8 Interact, no question! Fantastic grip, dual compound so you'll get great commuting miles, and best in class wet-weather performance.
I saw Keith at Total Motorcycles in Pooraka for mine.
Have a look and see if KillerNoodle is still making his clutch slave levers - no question this is the single best mod you can do for your Fizzer.
Other than that, the Fizzer is a surprisingly capable yet forgiving bike. Keep 'er under 8000rpm 'til you get used to the power delivery, and she's absolutely polite and tame - wind 'er over 8000rpm and feel the rush!
That's one of the things I like most - perfectly fine for doodling around town, but maximum fun when dial is turned up past 8000!
LOL!
If you need any help/advice or have questions re. the Fizzer, just ask as I'll always help if I can.
One thing you'll notice is that the Fizzer has a soft front end, so you may want to have your shock-springs upgraded, and what do you have your rear shock pre-load set at?
Get decent rubber, check your chain tension (the Fizzer chain looks loose, at spec, but isn't! 45-55mm chain slack, as measured midway between the front and rear sprocket) and keep decent oil in 'er and she'll give you many miles of trouble-free motoring. (mine has over 55000kms, and still runs perfectly)
Cheers,
Rick
