Rear shock was replaced last summer. It was already discussed here.    
	Run time is unknown yet.  Will  update as soon as I have more data.  Need to fix few more things.  
	quality of these bikes is horrible so many things got replaced so far. 2 sets of lead batteries, motor, both sprockets, rear shock, 2 of original throttles, ignition switch failed and was bypassed.  
	need to do: throttle one more time, front fork, all brake calipers, will get hydraulic brakes.
