Hi hope you can see the picture of the old and new seat its the low comfort seat from triumph part number A2304333 fitted today not had a chance to ride it yet but initial thoughts it does not look 20mm lower than the standard seat as hopefully you can see from the picture but when you sit on it the seat compresses more than the standard one which is were I think the 20mm lower comes in. I really like the way it looks but sadly I have a feeling that its not going to be any more comfortable than the original. Will let you all know how it goes for anyone that may be thinking of buying one for comfort.
