My c50 seems to run OK on 87 octane but has a little better power on 89. It is equipped with cobra pipes and a power commander. The difference was noticeable when I switched. I had been running 87 octane for about a thousand miles. This is a "seat of the pants" observation tho.
In the US, the cheapest grade of gasoline is best. The owners manual calls for 87 octane and the 805cc engine has a low compression ratio, which has no use for higher octane fuels. I've done 34000 miles on my '05 C50 burning regular and it hasn't missed a beat.
The recommended octane rating for a 97 Suzuki King Quad 300 by the dealership is 87. However, it is found that the bike runs smoother on octane rating 89 with 10% ethanol.
An '85 Chevy Caprice Classic takes standard unleaded fuel (87 octane) unless if it is a Diesel engine. Higher octane is okay to use, however I am uncertain if it is okay to constantly use a higher octane.
What year bike? I use 87 in mine and I've looked into it like you are and everywhere I checked said 87 is the grade to go with.
