Had a lot of time to think yesterday and one of the things that sprung to mind was what was the ultimate bike modification? If I could have 1 thing added on or changed on my bike, what would it be?

For me personally, I would love an electronic mirror memory, like on my car - so that once set, every time I start the bike, the mirrors go back to their pre-set position as im forever nudging them when getting it in and out of the garage, washing it etc and I can never get them back where I want them afterwards! :-?

So, if you could have 1 modification on your bike wishlist, what would it be?
