Update on my motor cut off issue. Sondors support sent me a new display but it did not resolve the issue. Support was then very quick to offer to send me a change out battery (I have to return my original) when I told them some of the details of the issue. I told them the display and the motor always went off together. I told them I was able to restart the motor using the display ON button most of the time, but other times I had to us the downtube on/off switch to turn the motor back on. Wondering if others have had similar issues? I will update when I get my new change out battery and have time to test it.
 
Update on the motor cut off issues after testing the bike with the new battery. I did one 3 mile ride, then a 5 mile ride with no motor issues. Before the new battery the motor would turn off around 10 times in 3 miles. So, looks like new battery was the fix. Sondors Support was great. Don't know how it could have been any better?
 
Actually I sent this to Lightning 1 2 3 because I remembered he had talked about the Fork upgrade to his Rockstar. Thought I would send it to all:
I still have my original fork but am thinking of upgrading to a Yari or a Lyrik. First, was the difference really noticeable for, I will say, medium rough single track? I think I read that the Yari and maybe Lyrik really smoothed out the rough stuff. At times I do ride in somewhat messy single track with roots and some rocks. Anyway I was looking back at the previous posts and thought I was touch base on your overall thoughts on the new forks. Thanks r.lee

If you are considering a new fork, before you buy a Rockshox take a look at the Wren Inverted forks. Go to the factory web site not a reseller. Direct from factory is often cheaper.

I think it’s 15 x 110mm,
might be this fork https://www.srsuntour.com/ga/products/fork/AURON-6800.html
although I forgot how the original looks.
Hi, I had the same issue with my front fork. I've pretty much been able to determine that the fork conforms to "Boost" dimensions which are 15 x 110. However, the stock front axle is 165 mm long and every boost front axle that I've seen is only 158 mm. Not sure about the Thread but suspect it's 1.5.

I was forced to order a stock front axle from Sondors. Still waiting. I'd like to replace that with a "Stealth" axle. I'm not fond of the Quick Release.

Onto the front axle.
my lever pivot broke today and searching the web for a 15mm x 162mm axle turns up nothing.
Has anyone found a replacement front axle?

A bit more ... I've ordered a Wolf Boost 15X110 with a length158 mm and a Thread Spec of 1.5. Since the threads and length of original axle are quite bit longer than seem necessary to tighten it, I'm gonna give this a try. I post the results.

Rockstar Axle Update. The Wolf Boost Axle, while shorter than the stock axle, is working temporarily - at least until Sondors sends me the replacement axle. It only threads about ⅔ of the way into the locking bolt on the left side, but when tightened, holds everything in place. I will likely do what was suggested by a fellow on the Sondors Rockstar Owners Facebook Group, which is to purchase a longer 15mm axle, cut it to 164mm, and use a thread-cutting die to extend the threads to the 21mm as they are on my original axle. Otherwise I DID find a 15X100x163 axle on modernbike.com, but it's $114 and Out Of Stock.
