91RON unleaded.

So then we can't really go on Honda's numbers either Stickshift or what do you think?

Honda's figure is as accurate as they want to report it.

Putting anything higher in than 91ron won't increase performance unless you've raised the compression or advanced the ignition to the point that it's detonating on 91ron.

Just a quick note from an engineer...

BHP is BRAKE horse power, the brake part refers to being at the crank;

HP is just horse power, ie referring to that produced at the rear wheel.

So, rear wheel power is stated in HP, while engine power is stated in BHP.

Hope that helps!

I use shell VPOWER 1 in 3 tank fulls, ive no idea why, but ive done it with all my bikes. I think its all personal preference.
