Features

  • COMPATIBILITY: This Warp 9 Stem Lock is compatible with a variety of E-Motos including Talaria Sting, Talaria XXX, Surron Light Bee, E-Ride ProSS, 79Bike Falcon M (with Warp 9 direct mount stem), and Segway x260.
  • VERSATILITY: includes 5 steering tube height spacers in 20mm, 15mm, 10mm, 5mm, and 3mm sizes.
  • NO MORE LOOSE HEAD BEARINGS: Tired of fighting your head bearings coming loose? Chances are the OEM star nut keeps walking up the steering tube. The Warp 9 Stem Lock kit includes a threaded rod that runs the full length of the steering tube, compressing the lower triple clamp to the upper triple clamp ensuring your head bearings stay tight.
  • MULTIPLE COLOR OPTIONS: Match your bike style with one of our many color options. Color options include black, blue, red, gold, purple, and magnesium.
  • SMOOTH RIDING EXPERIENCE: If your bearings become loose or damaged you will notice the steering and handling of your bike will be greatly impacted, possibly resulting in your bike becoming dangerous to ride. The Warp 9 Stem lock fixes this issue and ensures you have a safe, smooth, and enjoyable ride.

  • good quality, looks good on my mx3
Color: Magnesium
Arrived fast, and was just what I needed to get my headset to tighten up. I replaced both bearings thinking that was what was making my headset loose and was pretty disappointed when it was still loose. Turns out my star nut was just worn out. The stem lock fixed my issue, and i think it adds a cool look of personality to the bike. 10/10 would recommend. easy install even with the stock bar mount. ... show more

  • Stem lock
Color: Black
This should have been the first thing I did to my eride pro ss 2.0. It makes your head set feel really snug and smooth.

  • Works great for a Light Bee
Color: Purple
It's as described. There's cheaper stem locks and there's nothing particularly special about this stem lock.

  • Works much better than the Star Nut
Color: Black
If you are buying this, I assume you already know what it does and how it works. We replaced our traditional stem lock (star nut) with this one. We find these to be more solid and easier to work with when doing repairs or tinkering with your fork and handlebars. Tightens up very well. Don't over tighten though. Not clear on what this is made of but it is super lightweight. ... show more

  • Fits perfectly on my Talaria.
Color: Red
Fits my Talaria MX3 with Fastace Forks perfectly with the smaller adapter. Handlebars/stem feel solidly locked in for hard riding.

  • Warp9 Quality! Stem Lock is Mandatory! Dont wait until there's damage
Color: Black
One of the must do Mods for the average EBike. Keeps the steering stem Bearings tight and the steering head tight and correct. Otherwise damage can happen if it gets loose without this Stem Lock. Comes with Anti Sieze/Copper Never-Seize for the long main bolt so there's no corrosion down the road
