Thanks guys for the suggestions. the track is excellent, but being a middle east country its very dusty, the fine dust gets everywhere! the triple jump is the hardest and quite often we lawn dart the 3rd jump. (we run counter clockwise) By the end of the mains the track has a fine layer of lose dirt on most corners.
Most often front shock towers, front diffs, and front shock mounts are the common parts that break.
Hope we can pre-order a NB48 soon!
