I couldn't tell you what the average is, as I never let the level run down.

My reasoning for this is that on rare occasions, the oil pump drive shaft seal can become unseated, and slip down the shaft. This allows the 2T oil to drain into the gearbox.

Topping the 2T reservoir back up after every ride [and checking the level befpre every ride] ensures you spot the problem if it ever occurs.

However, I can tell you that a few years back I would regularly do a 206 mile "Devon TT" without fully emptying the tank.
