For those of you that read my pothole rondevoux, I am up and running again 330 for wheels 268 for metzler sportec M-1 mounted and balanced, for those of you who didn't I hit a pothole(2.5 ft long 1 ft deep straight down asphalt) in a curve 35-40 mph with a girlfriend on back ruined both wheels kept it up girlfriend is safe thats all that mattered, but back to bike, got them on last night went for a ride after a week I almost forgot how much I love the Busa. Now the metzler ? is the extra hum from the front the new metzler seems like it has more road noise? maybee from the deeper treads.
