## Description

Product description

Review: These things work. - Brought my suspension up to a new level after greesing my front struts and upgrading these it made bumps feel smooth and nearly non existent. Highly recommend for a huge moped upgrade or for many other things these are made for, these worked fine out of the box for the puch maxi i jist had to adjust the spring load a bit and adjust my muffler height with a small extension bracket i made because these added about a half an inch of height from my tire to my back fender. Its a bit more than i needed but i figured better traction would be safer and it hugs corners and eats the potholes i dont have time to avoid way nicee now and makes me feel safer riding. Out the box their decent but i hear theyre even better if you rebuild them and refill with full amount of oil apparently the factory doesnt fill them all the way so sometime down the line one winter maybe ill try to rebuild them and see if they come out even better as they say.
Review: Perfect for Nighthawk 250 Project - These worked perfect for my Nighthawk 250 cafe project. Direct bolt-on
