SX would be much easier on the stark, as the tracks are tighter and it's more about momentum and rhythm, usually on a hard pack track, so it's not being held wide the whole time and as long as the races aren't more than 12 mins. plus the help of the factory stark team doing everything to keep it...

I don't know, whys that?

Wow, so it goes to show its not just sand riding but anything where it is getting put through its paces. How long is a flat track race?

How long did it take to do 7-8 laps?

Yeah that's the issue, at 18.06 mins in the video, it was ment to be set at 80hp but you can hear and see the bike has thermal limited its self to be slow as hell. Looks like it only took a few laps for these boys.

Read it for yourself emails from stark. Thank you for contacting Stark. Sand tracks offer very little traction thus greatly impacting efficiency, as the wheel spins constantly. What you are describing is consistent with derating. That means the operating temperature is reaching the limits and...

The tesla performance battery's are water cooled, I think if your going to produce a electric motocross bike it has to be built like this in the future, finger crossed honda or ktm capitalise on starks mistake. Not the review I wanted to give the stark, but that's my honest experience and...

Yeah there is lots of people around the world much faster than me, I can't be the only one having this problem. Great bike, alot of fun to ride but when it comes to a race bike it's more of a toy than a tool.

It's the middle of winter here in New Zealand and the sand is pretty wet, so it will only get worse as the sand gets softer in the summer and the temperature gets warmer

I found that to get the bike to steer with the rear wheel like a gas bike in sand it had to be on 65hp or 67hp anything less it would get to much drive and push high and or go over the berm. Engine braking I found about 35% was good as it settled the chassis in the corner better and carried more...

I have a different power issue, I'm riding motos on a sand track. The stark is thermal limiting itself at 7 minutes and by 10 mins is going so slow. The battery is getting hot and putting itself into a limp mode. After a month of testing and lots of emails back and forth with stark. stark admits...
