rear shock
 

I have a jonway 50cc 2t and it rides really stiff.im surprised cause im 175 pounds.it takes a 320mm rear shock or 12 5/8 eye to eye.i was on ebay looking for some adjustable ones but they look beefier than what I have on mine.has any one bought a after market shock they were happy with?some are $50.00 and some get up there in price

There is a company called Doppler that makes air shocks. You adjust the ride by adding or removing air.

thanks

I have a Tomos 50cc & the front has a noticible 'banging' noise when I hit a pothole. I don't think it's the front shock. Any suggestions?

The steering headset/handlebar/fork stem assembly might be loose. Usually you can loosen it up, snug everything back together, and tighten it up to get rid of the slop where the fork stem goes thru the frame.
