I'm not opposed to catch trays however I do question there relevance on bikes with dry sumps (a large number of the classic bikes), if there is an oil leak and the engine continues to run fine then most likley the oil is coming out as a fine mist at high pressure, something a catch tray will do little of nothing about.......... If there is a hole of a sufficient size to allow oil to run out then there isn't much in the engine to run out anyway and the rider would realise quickly that there is a SERIOUS problem.

As far as I am aware the oil containment rule was bought in the stop a wet sump bike (some of the classics) dumping several litres of oil onto the track following a "rod through the cases" type failure, as several litres suddenly dumped would be very difficult to clean up from the track. This oil containment system has done virtually nothing to stop oil getting on the track during general engine failures as demonstrated at virtually every BSB round wen at some point sessions are red flagged to clean up oil.

If it is concluded that a catch tray makes things safer then I will happily fit one, but the issue should be properly thought out and not just decided by a knee jerk reaction. For example removing the (new in 2005) double solid white lines that were a major contributing factor to my dad's crash on the mountain would have improved safety far more than the TT - course license imho........
