Altis rattling noise when driving

Hi all, when driving the Altis I’m getting a rattling noise. I think it’s my chain guard lower but I also noticed this little metal ball near the shock that moves around like a bobble head. What is it and could it be making the noise I’m hearing?

Altis Sigma MX Upgrades?

Just picked up an Altis Sigma MX and looking to start upgrading it. Wanted to get some REAL user feedback before I start throwing money at random parts

Curious what you guys are running for:

Handlebars (brand, rise, width, size, etc.)
Aftermarket seats (if any exist yet specifically for the Sigma MX)
Grips, especially throttle-side compatibility
Preferred supermoto tires/setup
License plate mount
Chain/sprocket setups
Better phone mounts

Trying to focus mostly on comfort, handling, reliability, and overall ride feel right now — power mods can come later.

Would love:

pictures of your setup
what worked vs what didn’t
links to parts/vendors
any “must-do” upgrades for the Sigma MX platform

Thanks guys
