I've seen five or six magazine tests of the 12-13 which reported top speed - all are 124 mph +/- 1 or 2. This is probably without accessories, tucked in, sea level, etc. Assuming the average 8% error of the 12-13 speedo, this would be about 136 indicated. This is consistent with what you'd expect of a low-90's RWHP engine and a relatively tall/upright bike with a lot of frontal area.
