Your thinking is correct. This is exactly what I spoke about earlier in this thread. Take a look at the pic I posted on post #22. That is why I used this example. It is the only shroud design that I have seen that guides the airflow towards the air fins and doesn't leave a gap for it to go beside the radiator.
those angled vertical fins across the frontal section of the radiator are old skool, dating back to the mid 80's from what i remember. i think there may be far better ways now days and we can learn from modern designs. every year ktm seems to be putting forth alot of effort to make their bikes the best and you can see theyre even adressing the little things like the fins across the front section of the radiator. by changing their shape they increased cooling efficiency 10% while mantaining the same coolant capacity and rad surface area. i have drawn red lines to represent what i believe is a close proximation of what their shape is but its hard to tell just from that one pic. it seems to me that rather than just a angled fin like whats been used for ages on nearly every mx bike, they have shaped the fins so the air turns back straight as it enters the cores. and those rad scoops that are angled outward at a rediculous angle, something tells me thats not the best idea. anyways heres a snippet from a article on these rad gaurds
KTM’s engineers put lots of thought into their radiator design. Rather than just put old-school plastic guards on the front of their radiators, KTM used wind tunnels to design a new radiator guard shape that flows more air (and is made from a stiffer plastic to help the flow and act as a radiator brace). The radiator shrouds also seal against the outer edge of the radiators to direct airflow into the radiator’s cores. There is a new filler cap and filler neck that seals better than last year’s design. The end result of all of this work is that the exact same capacity and surface area produces 10 percent better cooling efficiency
