I think a lot could be done using those ideas. A few small changes and that would make a great neo-XR bike.
I definitely agree with those that were wanting to see some interesting Harpoon paint schemes on it. Maybe a cream and black satin finish that harkens back to the look of the old single striped racing leathers.
If you haven't seen it I think it's the Motorcyclist this month that has the Mert Lawill flat tracker tested, said it will keep up with any sportbike on the back roads and makes about 90 HP. It also has a two page feature on the XR 750 dirt tracker that weighs 274 and has 100+ hp,. of course I will never be able to have either since the new version is $29,900 and you can't find a XR750 for sale ( or at least one that I could afford).
