My trap was dispatched on the Monday morning, and it was with me on the Friday morning in the UK. 10/10!! The Zipper trap door is a lovely looking piece of kit. Pity that it's going to be hidden. For those of you aware of 4 speed Evo sportsters, the double width bearing should help our gearboxes become a bit more robust. Just waiting for a repair to my rotor and we'll be off............!
