Not sure there is room for a 15T front sprocket, but that would be a big change anyway(13T to 15T). I think 13 to 14 would be about a 7.6% increase, or 60 becomes ~64.5mph at same rpm, right?

2T isn't too big of a change.
On my X-Pro 150, I swapped out the front 15T for a 19T.
I still can wheelie in 1st(with pulling handlebars), but no longer in 2nd or 3rd.

It did lower rpm from 8.7k rpm at 55mph top speed, to 7.5k rpm at 60mph. Top speed increased, and rpm lowered to peak HP of the engine.
