Which fuel to Use

[newguy9000]

I have a 2008 CBR125R (The fuel injected version).

What octane fuel (91, 95 or 98) should I use?

Thanks! :apint:

Whatever Honda recommend (should be in the user's manual, and if it's not, phone the dealer). Generally go for the lowest acceptable octane - anything else is costing you more and giving you no better performance.
Just bear in mind NZ petrol octane rating is RON.

As viffer said read the manual.

My guess is compression on that would be quite high.

So going on a hunch that it might not run very well on 91. 95 would be my guess?

How wrong was I heres a link...

11:1 compression, should run on 91 no problems. But check the manual to get a definite answer.

I use 91 generally. I have tried the higher octane stuff and whilst I notice very little difference in performance, I do get a few more Ks out of a tank.

Found on a Canadian forum...

Honda says: Use minimum 86 octane OR higher. It's a judgement call on your part to see if there is any noticeable difference in ride quality using Premium versus regular.
He got a response, too...


Thanks for the tip regarding the octane. I started using 87 in the cbr 125 for the last 2000km's and it seemed peppy-er. With the 91 and 94 Ultra stuff I found it bogged a bit. Also saved me a good chunk of money.

I think that'd be the same as the Mrkn octane ratings, where 87 is the equivalent of our 91RON.

your right. Their 86/87 is our 91. And they go upto 91 in 1 point steps so their 91 is about 96. And then their 94 is about 98-100 for us.
