Are you certain about the 130mm. I measured and it appeared to have plenty of space to handle the 140mm Metzler ME 880? Metzler states that the tire will fit on rims from 3.0 - 4.5 inches and the M90 front rim is approximatly 3.5 to 3.75 inches.
OK, well I think Im going try to make it work. By my calculations the 140/70 tire is 1.1 inches (0.55 inches on each side) taller then the stock 120/70. Currently I have about 1.25 inches of clearance between the top of the tire and the fender. this should leave me aprox 0.70 inches of clearance. Worst case I will send it back or adjust the fender slightly.
St. Louis, snow melt and rain yesterday morning. I went for a ride and as I crossed over a crack-fill (tar line) the front of the bike slipped. The front tire has about 12K miles on it and is due. I ordered a new tire as soon as I got home.
