I don't see any reason to lift the tail. The stock B12 already sits nose high, the 1.5in drop did not affect ground clearance at all. I have pushed the stock Michelins as far as I dare without any clearance issues under cornering or very heavy braking. The only caution is under lock-to-lock steering, as in parking, you have to be careful as the bars get close on the fairing. Actual riding is unaffected unless you are crashing.
I have been riding bikes with clip-ons for 20+ years, they feel natural on the B12. You counter steer easily and use rider weight to flick the bike side to side. It is not twichy at all, after coming off a TL1000S, it is rock solid. I do run Race Tech aftermarket springs as I like the front end stiff. But, this is not a commuter bike but a toy to blast around on.
I did not like the tubular bar at all- not only the bar but the way it mounted as well. It did not feel right and required too much steering imput. I got a smoking deal on my 2005 that justified making the changes ASAP. I could not be happier with the setup. Next plan is for Michelin Pilot or Dunlop 208's ,Mikuni RS carbs, and drop-in cams.
Ride On, Ed.
