  • Great for my cart
Color: Blue Size: 280mm
I have a 1997 Yamaha G16 golf cart with 4" lift. It had old shocks, so I bought these after I measured the eye to eye part. These were just a 1/4" longer. They worked precisely as wanted. They came with the shank for bolt to go through but only half the shank washer would fit my setup and I used some regular, flat washers to take up slack on other side. The cart drove great and feels more solid than it had before. These would be great for golf carts with a lift or any type of ATV or scooter. Obviously they won't work for a stock golf cart but since they're adjustable, I think they would fit anything with 3-5" lift. Update: you need to have the cart or whatever jacked up to take pressure off shocks if you want to adjust them. The tops tighten and loosen like a screw, so you can adjust where you want the coil and tighten the top. Also, I don't think the air valve is real. I tried to add some air into it and it doesn't do anything. Might be for looks or whatever, not sure. But overall they are doing good and drive my golf cart around quite a bit today. ... show more

  • Not strong enough
Color: Black Silver Size: 320mm
It fit but was not strong enough to hold the weight of my motorcycle. Even after turning the pre damper up all the way.

  • Perfect Bigniu BG-X Replacement Shocks
Color: Black Silver Size: 320mm
If you have a version 2 Bigniu BGX these are the shocks you want. The springs are lighter and way more cushy than stock plus the shocks are a little longer so at full travel the rear fender wont slam into your tailight. However don't just slap these babies on thinking it's going to completly solve all that bone jarring you've been experiencing you OR stop those gnarly creaking sounds when you hit a big bump or pothole. Take both of your stock shocks off first and make sure your swingarm is not bound up or locked solid from being over torqued at the factory with the wrong thrust washers on the swingarm bearings. Quick and easy fix is to loosen the swingarm nut until it moves free and just squirt some spray lube (not WD40) down into where the swingarm pivots. Then snug back up on the nut just enough that the arm still moves freely before installing your new shocks. The proper fix is to replace the thrust washers with shims that have the correct size ID and OD that only contacts the inner bearing race. ... show more

  • Ryker 900 front shocks
Color: Black Size: 400mm
I just recieved the shocks. I have a Ryker 900. On YouTube friends have told me the shock would improve my ride. When I install these I'll will post how they are? I will say they look good right out of the box. I wish the was detail on how to maintain and us them.

  • Used this for a similar sized motorcycle replacement shock
Color: Black Silver Size: 320mm
Good looking product, quality is not bad but I have not been able to dial in the right setting to make these right just yet so they bottom out a bit easily. Working on it though. The looks are great though and it is a fair shock overall in performance.

  • Great shocks!!!
Color: Black Silver Size: 340mm
I put them on my 1969 Honda CT90. The original shocks were shot!!!! I am 250 lbs and these barely compress when I sit on the bike. I even have them at the lowest adjustment. They will definitely hold up to me and whatever I need to carry.
