    if correctly installed it is part of a closed loop therefore no reduction in oil pressure, the oil just takes a longer passage via the oil cooler to get to the intended location

    Actually anytime you insert something that is not increasing pressure (like a pump) there is some pressure drop. Whether you can easily find a oil cooler that doesn't drop much pressure at rated flow rate ,I don't know. It would seem like the flow rate on the plain bearing engines would be lower so easier to find a cooler that can flow the lower required flow. On a roller bearing engine pressure is lower because of much larger bearing openings so flow will be higher. I would dare say of a cooler works on a roller bearing it will be ok for plain bearing engine.

      of course you can easily find a oil cooler that suits plain bearing cranks, eg honda fours are plain bearing and have been fitted with oil coolers since the 1970s
      the next generation of the gs plain bearing motors is the gsxr they had very large coolers for the SACS oil cooling system
      which featured high pressure and high volume oil flows
