Yeah, I guess the question is two fold.
How do you have a super quick bike with a low top speed?
What does changing the gearing do to the life of the engine/crank?
Ken, I might just be doing that and putting that stuff on my Magnum. I did just order a circuit pipe to put on this Maxi. You can't spin the Maxi's pedals with this pipe without bending/extending/changing to a magnum pedal setup and spacer.
We will see what the circuit pipe does. If it's still too high a top speed, then I might change the front sprocket.
