It's not the fault of the manufacturer ... it's the fact that there is not enough room in front of the radiator for the filter section if there is a trans cooler sitting there. It's also not as easy to tip back the radiator. Basic fact I'll attach a shot of my engine bay so you can see what I mean ... look at the 2 x red brackets that extend the top two radiator mounts by about 80mm
Here's the thing ... you go Russo or Ramjet if you want the very best kw possible ... you can still get good results from Orssom, Ziggy or some of the other OTRs that sit above the cowling rather than in front of the radiator.
