Starter Motor Torque for Electric Motorcycle Propulsion

[MechatronO]

What is expected in stall torque from a regular car/small tractor starter motor?

I measured 7-9 Nm on a starter motor I had lying around, and I'm not sure if this motor is crappy or if such performance is expected.
It was fed with 12V battery and parallelled with a battery booster (basically a transformer with 12V ouput). I couldn't measure the current, but the boosters 40A current indicator looked like it was going to hurl its pointer through the glass.

The reason I ask is because if it seems to have a reasonable stall torque it will propel an electric motorcycle.

These guys specify around 200 Nm in starter torque. Relastic?

At last I found something.

These guys specify this:

Doesn't sound too far from the starter motor I have after all.

Hemmings forgot to mention the gearing in between it seems.
