That seat is gorgeous. I was considering dyeing my stock seat brown, but I like to stay stock with a classic too! The only downside I can see is if you get caught in a shower while you are in a pub you can't easily brush the water off as you can with a smooth seat!
I find the stock Magura grips to be top quality!
Now you need to make those mirrors your own, I like CRG, great quality, you can see and they fold for storage or if hit!
