Whilst granted it amy not be much use concerning the Ten initially, bear with me here.
I fitted a cooler to the SR I built, and as space was short I placed it toward the back of the bike in front of the mud shield but in plenty of air.


It worked well, so placing one in an slightly unusual place on the Ten cold be an option? There's not much space around the headstock but what about on the side between the expansion tank and rear frame loop? Move the expansion tank somewhere?
