It's in stone.It is unchanged from previous years. Gearing commander says 5600rpm is an indicated 75.5mph which is actually 70mph.
I've made numerous unacknowleged posts about it over the years, pretty much anytime gearing commander was mentioned.I hadn't seen anything about the Gearing Commander figures before that I remember. The first thing I noticed were its figures were based on the stock instruments.
Gearing commander is supposedly speed vs rpm based on all gearing between the engine and rear tire, including tire diameters. This supposedly should give you accurate figures. Somehow they've managed to get it wrong. Are you not curious where the error is?I may very well never mentioned it before. It doesn't seem very important.
Which brings up a good question, is the digital speedo also ~8% optimistic, and of so how can it be corrected since you can't just throw a corrected gauge face from raceratb at it?
Agree with Ozart so long as clearance is OK and tire size available. Check the miati tire calculator:Just a note.
If you want fairly accurate results from Gearing Commander, change the tire circumference from 79.38 to 73.
Thanks, but one of us might be misunderstanding the other.Agree with Ozart so long as clearance is OK and tire size available.
got you ..thanksThanks, but one of us might be misunderstanding the other.
I was refering to this online calculator, called Gearing Commander.
The trouble is, it's inaccurate to the same extent our speedometers are.
What I meant in my previous post was to change the tire circumference value in the calculator, not physically on our bike, to get accurate speed values from it (the calculator).
