My previous bike, an FZ8S, was a rock when it came to engine cooling etc. Never had any issues with it.
My V4 Tuono OTOH, hates August heat and stop and go traffic; temp just keeps rising... Might be engine packaging or fan efficiency etc, but I4s seem to do pretty well in those conditions while V4s, L-twins etc get f**king hot.
Yeah, Tuono has always run hot. I went on a ride once that had a KTM 390 and a Tuono competing for who would shutdown first in stop and go. KTM won.
