My motor peaks out at 9000rpm
my reduction box is 3:1
my final gearing is 6.5:1 (11/72)
so I make that 19.6:1 overall gearing
my rear tyre is 100/90/18 so circumference is 1.98m (yeah we are metric over here!)
So I get my 9000 reduced to 3000 at the box then 460rpm at the wheel for 911m/minute .... 55km/hour
Question is .... hows my math?
2nd question ... hows my torque gonna be?
All hail the gearing gurus!
