Exactly! 8 bolts to change the plastics and it's a whole new bike
Thats a really nice looking bike JP
I would recommend Q3+ for the track and street. A Rosso III would be nice, and I hear the B22 is as well. The Q4 and Pirelli TD is even softer and won't last.
By 19mm "upgrade" do you mean a radial MC? You can use the OE EBR 1190 one, or any 19mm (3/4") for 7/8" bars. I have one if you need it.
The tech spec are expensive, but I really like them. They don't mark up my white leathers, but are still sticky enough to work.
I use Oxford grips and like them a lot. They also have a series of "Fat grips" that fill my clenched fist for dramatically better bar control.
Good luck and have fun with it!
