Hey thats great! thanks!

Just one question whats the difference between front 120 (55w) and 120 (58w) ??

OR

Rear 190 (73w) and 190 (75w) tires?
Similar to a speed rating, correct? Higher # means greater speed I believe. Somebody correct me if I'm wrong here.

120/60 front tires have a 55w rating - "120" is the width of the tire, "60" is the tire profile (the profile height of the tire is 60% of its width) the "55" is a load index and "W" is a speed rating.
120/70 front tires have a 58w rating.
190/50 rear - 73w
190/55 rear - 75w.

Dont worry too much about the ratings. Just get a tire which is the right size for your bike.
