    Two Questions!

    Will be picking up my 2016 RT in the next few weeks (still have over a foot of snow here!) and am curious about a few things! What is the capacity of the side cases (Panniers?) and does the wethead have an oil cooler in addition to the liquid cooling rads?

    Nope. Both sides are radiators for water based coolant, only one fan. Check the parts fiche:http://www.realoem.com/bmw/enUS/show...diagId=17_0671

    No oil cooler on the Wetheads.

    Panniers 33 liters each.

    Thanks for the correction and pannier info! I'm sure T6 meant well!

    Panniers on my 2015 RT seem about 20% larger than those on my 2008 RT. I'm using the RKA liners from my 2008 and there's still a lot of room in the hard cases.

    As to cooling, I find that there's a lot of heat which seems to come from the LH radiator (the one without a fan), but not as much from the RH radiator. Odd but not a problem.

    You're going to love it a lot Crusty.

    This shows the interconnections between the radiators, if anyone cares:

    John, I believe that is because coolant flows through the left rad first and then to the right-side rad (w/fan) from the left one, if I'm reading this BMW graphic correctly.

    Initially, I'd thought they were using the wrong orientation, but then it donned on me that what they are doing is allowing the passive cooling of both the left and right rads to do there work and only require the fan intervention after the passive capacity has been reached. At least, that's my take on things, and I like the design.

    Crusty, congrats on the new bike, I'll be picking my "new-to-me" (916km) RTW just west of Toronto once the weather gets away from the real possibility of snow between there and my ride home to Nova Scotia. ;-) I'm sure you're just like me and have very itchy feet right now.

    Great responses guys! GMan-the illustration shows hot coolant entering at the bottom of the left rad! Usually hot coolant enters at the top and exits from the bottom! Fanigly point but I am at work and very bored right now! Yes Alan-very excited about my first Beemer! Having an early spring here but so far only have the VIN# and the dealer said the bike should be in any time! Awsum weather here but the long range shows a bit of a cool down for the next 2 weeks so I think mother nature is messing with me!

    Alan - I like that graphic a lot. It does explain the greater heat on the LH side. Thanks - JG

    Interesting. I moved from a 1200RT to a '15 GSA in November. I have noticed additional heat on my boot with the wethead, but it's on the right side, not the left side.

    Had to take both left and right upper panels off to confirm
    NO oil cooler insight, I never would have thought

    Water is a more efficient cooling medium than oil so typically you'll only get an oil-cooler on a water-cooler engine that is doing "severe-duty beyond the ability of the water radiator capacity available. Normally a packaging problem in not being able to economically fit sufficient water-cooling.

    Not only does the RTW not have an oil-cooler, but by going to water-cooling (and larger rads/coolers) it has increased the "non-air" cooling by over 50% from the previous models 22% cooling by oil to the RTW's 35% cooling by water. Because water is a more efficient cooler, BMW was able to generate more power while reducing fuel consumption and reducing emissions. All good in my books. Some may not like it, but we've always got great Cam/Hex/Oil/Airheads to fall back on it we wish.

    We have five water cooled bikes of assorted brands. Not one has an oil cooler.
