I think stuff will be kicked up at the motor regardless, because of my preferred high average legal speed, plus on my bike the motor isn't situated as far off the road, as would be on other bikes. Thanks for suggesting pond liner and shed roofing (felt?) - I'll get around to extending the mudflap with some sort of material. Seems I can secure using nuts and bolts.Why not just extend the mud flap ?
I did so on my Kona Ute, I have some old butyl pond liner /shed roof covering over and cut a pair of extra longer extensions for my mudguards.
Front one protects my down tube and TSDZ2 from damage and the rear one protects my trailer cargo contents from debris splatter.
