I could try quoting multiple sources here but what it boils down to is this:
1. You can try doing the donor fork internals thing and keep the original brakes, triples etc
2. You take the plunge and do an entire front end change out.
No, you wont make the bike out perform you.
Yes, the bike will do the basics as standard with some simple cheap mods.
But doing it properly will make it so much better to ride that you'll start taking it places it really shouldn't go. Then doing things it really shouldn't do. You'll look at a track and think "Yeah...I can get up that".
That's when the adventure starts.
That's what's it's supposed to be all about. Giving yourself the best shot at getting out there and back in one piece and living the dream into the bargain.
With the F800, BMW got so close....I got closer.
