Then run the best premium you can get. 98 should do it.

And for those who don't know, his 98 is a RON number and is roughly equivalent to the USA's 93 R+M/2.

Just keep in mind...the higher the ratio, the higher the octane. I would at least run 98(93). If you do strip/track days, I'd try to get ahold of some race fuel. Here it would be 101 or 103...not sure where you live.

Euro Super 98 is just fine.

I've used it for at least 8 years in my 1109 and with many many track days and dyno runs with base gasket removed and 0.2mm skimmed from the head.
No problems at all, and it is still pumping out 152bhp EC on Dynojet dynos.

The 1109 kit with a standard ZRX head and base gasket is nowhere near 12-1.
The 1109 kit was designed for a ZZR1100 (ZX11) and the 12-1 compression quoted is for that.

Hello Purgeraptor,

If the compresionratio with a standard zrxhead is nowhere near12-1 than i can stil run euro 95 right.
I have read some technical info about other bikes that have standerd ratio of 12-1 and they can run on euro 95.

[Purgeraptor]

You'll be OK on standard Euro 95 RON with a Wiseco 1109 kit.

I have done many miles touring in France on normal unleaded with no pinking or damage.

For trackdays or full throttle dyno runs, I'd recommend using Super.
