Hi Mel, thanks for the photo and info on Dave. The reason this Kat has an oil cooler and 4-1 is because this Kat is the ED2 prototype by Target Design and not a production 1100 Katana. Why the sexy 4-1 pipes and oil cooler were never fitted as designed was a cost and time saving measure from Suzuki. The production Kat frame was designed and built with the oil cooler mounts, but as we know - no cooler. This photo also shows the flat ED1 seat compared to the sit into seat of the production Kat. The ED1 had no screen or anti-dive and not the larger rubber cowl fins as this photo shows.
Cheers.
