When it comes to mass, I do not use the bike mass only, but the bike plus 100 kilograms (for the rider and gear). Why? Extremely light bikes loose some of their power over mass coefficient advantage - and this is what models the real conditions better than just the machine mass. If I was ever to consider two-up touring, for such bikes it should probably be mass+180 kilograms.
My lists include the seat height and rake angle, but not the torque numbers. This is the list of things I need to know to find real contenders.
May I suggest that you put units in the column headers? If it was possible to generate (since the numbers are already sitting in a spreadsheet?) the output in SI units (for instance, power in Watts over mass in kilograms) this would be terrific (for us in the rest of the World
Good suggestions rotor. It's supposed to rain today and tomorrow so I'll continue to work on the spreadsheet. For me, low end torque (2000-3000 RPM) and a relatively flat torque curve is more important than peak HP.
