DYLs i think are simply assemblers... theyd import stuff or order to a vendor and simply fit it up.
They have only one 100cc 4stroke engine that they are putting it in each bike.... so they are dumb heads...
All Mini100 customers will be paying for in this bike would be the engine... and that too would have BIG PROBABILITY of quality issues due to improper handling while assembling it... thus 4 me... it buying a DYL is a Gamble.
If this engine would had been upgraded by simply increasing the bore - stroke(like adjsm did), modifying the gear ratios, and carb modified for better mileage then this bike could have been a 97/98cc econo engine with limited fuel input possible through thinner valves and better power - good enough for this frame...
But the nut heads did not have any brain... they simply fitted the same engine again.
