High speed motor wanted

[henrikga]

Hi All

I'am tuning my electric atv.

My problem is that the gear reduction is 1:8 and the wheel diameter is 1.32 meter, so i need a small 3-5Kw motor that runs 6600 rpms at 48Volt, then my topspeed will be 67Km/t


Anyone that now where i can get such motor

I'm there too, my express has like 12.5 to one ratio (& 20inch tires). I'm just gonna go with chain and sprockets though, since I already have the motors.

Is that ATV shaft driven? I'm having trouble understanding why you can't alter the ratio?
