here are my builds, i have had the same bike the entire time, my bike is beat to crap, in these pics i will show you, this was my first build, had around 3000kms on it at time of picture.
this is my second,
and this is my curent build, so far the 4 stroke is better than any of the 2s, way more power and speed, and better on gas,
i have about 700kms on my 4 stroke, now do the math, my bicycle has so many kms on it, its beat to crap, the above pics where of it 700kms ago, my frame has snapped and was welded back together, my front tire has 2 inches of wobble back and forth, my back tires bearing has half an inch of play, i have no back break cables, or pads, so only front breaks, everything about this bike is falling apart, but i must say, for what i have done to it over the years its the best bike i ever had! and get this, my front tire has the same rim, tire and tube it did when i bought it 5 years ago, thats right, i have like 7000+kms on the same tube!! i have been through many back tires and rims, i used to go through a tube a week, , i have been through 3 back rims, but hey, its transportation!, and i love it,
