well i dont know nothing about this, but when i bought my CEN CT5 Subaru they said 73.4 m/h and 35.000 rpm...
Since it was tuned up, it runs very very fast, at least for it size... but i cant have a true number just by look at it...
i never really found a space where i could push the second gear all the way to the top... Another problem is when it is at second gear it is very unstable, almost any little rock
makes it to go out of way... i can tell you that running with it at night it's pretty cool the sound is spectacular (since at night there are less noise around)...
