Answer:

Personally harley davidsons are the best you can get. If you treat them right they will last forever ad fun to drive
i'm 5'3 and i have a dr350i can touch ground with one foot and the dr350 has to be in 5th or 6th(top) gear just to reach 50mph.i think a 250 would be a waste of cash as it probably would'nt be too enjoyable.i believe the dr350 can reach up to 85mph(have't tried it yet) i would say just to get something that can do highway speeds comfortably and your height shouldn't be a issue on any bike
Fe2O3 or Iron (III) oxide is one mineral used as iron ore, it is preferred over magnetite, which though it carries a lower iron content, is easier to beneficiate process than magneite is. Iron ore mining companies prefer to work haematite than magnetite. Magnetite is within the Spinel group of minerals X2+(Y3+)2O4 which are all characterised by processing difficulties. A further iron ore mineral is SIDERITE, FeCO3 which is iron (II) carbonate. This mineral occurs in reduced environments within certain sandstones shales but more commonly in hydrothermal vein systems. As an iron ore mineral, it is far less important than hematite or magnetite.
