You know, Gavuk, I never thought of that. Its not easy being on my own to stand the bike up, straight, to measure the seat height accurately, with it only having a side stand. I have the bike currently placed into one of those wheel chocks. It leans a bit (i haven't got used to a wheel chock, the bike doesn't seem to fit tight into it, and when I pit a yard spirit level across the handle bars, it feels as though it's going to fall over, but i've managed it and with these "lower" links fitted, the height is about 815mm. i think thats somewhere near the standard height for a 17 model. I've gone and ordered some Lust ones.
Normally i'm not keen on lowering, but i can touch the ground with (nearly) a flat foot, but it saps your confidence when you stop and there's a strong camber on the road, or a bloody pothole you dont see.
