What do you mean - possible parts bike???
You've finally found the perfect candidate to customize and satisfy the cafe urge!
And along the way, you've also discovered why we all cringe when someone shows us a pic of a perfectly good beemer they're going to cafe.
It's not because we're purists or anything else - they're just so cool as they are, but take a little "getting used to". Looks like you've figured that all out. The best route is modifying a project bike - hopefully this one has a sound engine and transmission! And even though you don't believe it, it's quite possible the mileage is correct.
