The additional brake line was a joke by someone (or they've been misled).

The R1 model has another oil cooler plumbed inline with the original cooler and block.

Oil temperature is very important as it is the most direct method of regulating heat on the internal portions of the engine. The cooling system is a heat exchange process used to regulate and take away heat that is conducted through the walls of the housings. They both are very and equally important.

 

i agree w/ get the one in better condition.
then go buy an oil cooler.
