The oil moving rapidly

The Suzuki Gsxr hit all the critical points

The central idea in getting oil cooling to work properly is to force it onto the surface with sufficient energy to break through the boundary layer - that area where the oil movement tends to slow and heat builds up - and to keep it moving in sufficient quantity to move the heat out of the engine through an extra-large oil cooler.
The drainback tubes highlighted in the front of the engine help keep the oil moving rapidly back to the extralarge sump.
