Its my first prototype, and from my first 35km, i can say its designed for high rpm power.

Up to 37, 38km/h i dont notice a big improvement, but past 40km/h, it pulls like madness
 
Nice

Cool ride. Do you see or hear of others in your area who have MB's.
I had that same kickstand and seem to bend, now i got bi-pod kickstand from walmart $20 Me likee.
 
Stock is always a quite quieter, but is not very loud, i think the soud its perfect for a plenty ride :)
 
I like the left side mid mount and the zig zag under the seat... very innovative... I think ill have to try it.
