Thanks guys.
Rode it today - I am in shock as to how blisteringly fast it is for a 125. Feels like my old '98 RM250 with more over-rev. Bottom punch is still good, transitions to mid-range smoothly, and just goes Warp Factor 9 through the top without signing off. I've got to get to a track now and see how Enzo did.
I love this bike. Need your engine modified? Call Tom Morgan.
