That watercooled engine is built for a load transporter not for funrides. With those things the asians move loads exceeding the payload of an US 1500series pickup truck. Slow, but it works.Just saw this and want to throw in my 2 cents on the original water cooled photo. I think its definitely overkill, people have been building big power air cooled 200-300cc Daytona's without cooling issues only running an oil cooler. Was talking with a guy on FB and he made a good point on the xr650 and how it was one of the best desert bikes ever created and was air cooled. I have always talked crap about air cooled motors but now im thinking its efficiency is a lot better than what i thought.
