If it’s good enough for surronster it’ll be good enough for you
What can I say that the title doesn’t already i bought the 30mm & the grey colorway the grey is way more shiney than the picture shows which is nice if you like more shiney parts or bad if you prefer more matte look personally the shiney is cool catches the light nicely, 30mm was suggested by the manufacturer for a surron this will fit a talaria mx4 &/or talaria XXX those are the only bikes I have to test but obviously works with surron as well i cant speak to something like a throne srpent or anything like those. But overall i like how much space there is in the middle if you have a large display or a phone mount, additionally they feel great nice & durable the machining feels superb & not to heavy & not to light just perfect now I don't take this off road it is a pavement princess but i know surronster has taken these offroad many times so im sure these will hold up just fine they wouldn’t make a special size if they werent confident it wouldnt hold up

Worked out perfectly
Bought this to replace the stock stem on my Sur-Ron X electric dirt bike. The stock one kept twisting when the bike went down out on the trails. (It happens) It was easy to remove the stock one and replace it with this one. Great fit and finish. Seems well made and looks good. I bought the one with the 30mm rise so it would keep about the same height I had with the stock one and a Protaper Handlebar with the 3" Rise that I had previously installed. It also didn't interfere with the Sur-Ron headlight.
