Half way between the two Brands Hatch junctions - 30 mins only wait for SOS Recovery.
Damage appears to be limited to snapped and bent Oberon clutch slave bolts, the metal 'chain fail' protection bracket (did it's job) and associated plastic clutch pushrod/pin restraint bracket, broken number plate, small chunk of crankcase next to the clutch oil jet and minor gouges to rear wheel hub (hopefully not enough to do a Maxime Berger once back on the road)- lucky, I guess.
All parts with me by Friday courtesy of Redline/Oberon.
