Very much enjoying my first season on my 2008 K1200 GT and headed for a two week trip to Northern Ontario at the end of July.

Done this before on other bikes and I know that I will be stretched for gas in several remote locations (e.g, Chapleau). I know that is not possible to get gas over 89 octane in several areas I plan to go through. At 13:1, I imagine this is hard on the engine, even if the spark adjust, ignition and combustion chamber are state of the art.

Any recommendations for an octane boost product that is safe and reliable?
Remarkable amounts of hype out there.
