You had calculated in drive train loss for max speed, which isn't needed or correct. That was what I was referring too. I've tried to get the correct math, but I just can't seem to get it. Using my old formula's for my Mustang and Tundra (I did this to show the cruising and top speeds in all gears with different gear ratio's) it says you'll go 105mph in 1st on the WR. ha ha. I did get one formula to say 34mph in 1st at 11500 red line, but even that seemed to high. I don't have my bike in the garage this week, so I can't go and test it out. Are you using the standard rear tire to get these figures? 110/100/18, which is what I believe stock is. It's 26.6" diameter tire. Can you share the formula? I'm curious. here's what I did for my Tundra: http://3.8mustang.com/justang/Drivetrain/Tundra/Tundra%20gears.xls I'd like to do that with the WR as well.
