One might wonder how many of the Japanese contingent, by percentage, are Honda, Kaw, Suzuki? Are their riders similar in overall pecentage vs the HD riders? This would be relevent to the overall percentages by brand loyalty. Somewhat, anyway, not counting the difference caused by so much lower prices on Japanese products.
This might mitigate to some degree the overall metric vs sae vibe that won't seem to go away. Some might think it to be the entire reason for this exercise. But we all knew there were more metric than HD. I couldn't begin to understand why overall numbers would be important anyway, other than for the smugness factor, if I might be so brash as to suggest that.
