Please Note:

*The 20MAXX  and 20MAXX VIBE phone cradles are part of our "MAXX" series and offer Heavy-Duty spring tension. This level of tension is specifically engineered for Motorcycle, Extreme Off-Road, SXS, ATV, Open Top Driving, and other demanding applications.


  • Unlimited M8 Bolt Mounting Options: Our innovative Riser Bolt Mount allows you the flexibility to swap an M8 bolt on your Motorcycle with a new M8 bolt that accommodates a 20mm ball head. We understand that different Motorcycle manufacturers and models require different length M8 bolts. To accommodate your specific application, we include (3) M8 bolts measuring M8 x 55mm, M8 x 60mm, and M8 x 65mm.
  • Universal Phone Compatibility: Our phone holder is designed to seamlessly work with nearly all smartphone models, cases, and sizes. While you're on the go, it ensures a secure fit for any device, whether or not it's in a case. Capable of securely holding devices up to 3.7" wide and 0.6" thick. Please check your device for proper fitment.
  • (Optional) Vibration Dampening Phone Holder: Motorcycle vibrations have been known to adversely affect the image stabilization mechanism in some new smartphones. Our Enduro 20MAXX VIBE cradle reduces high frequency vibrations transferred from your motorcycle to your phone, reducing the chance of damaging your camera.
  • Innovative Cradle Design: Experience the difference with our specially designed cradle. Unlike standard spring cradles, our octagon-shaped grips minimize heat transfer by pulling the phone away from the cradle's back on hot days. The spring mechanism is perfectly calibrated, allowing for effortless single-handed insertion & removal of mobile device without straining the mount base.
  • Clip-In Grips: Traditionally, our previous generation phone cradle utilized double-sided 3M tape to secure the grips onto the cradle, a method commonly employed by other brands with similar-looking holders. However, in high temperatures, the double-sided tape could loosen, causing the grips to peel away. Our Clip-In Grips address this issue.
  • Cradle Pin Sleeves Eliminate Cradle Buzz: Cradle buzz is a common issue in many of our competitors' current products. These metal cradles feature steel pins that run through them to support internal compression springs. However, the metal-on-metal contact, combined with vibrations from vehicles or motorcycles, can result in an irritating buzzing sound. We've eliminated this problem in our Enduro cradles by 'sleeving' the pins, ensuring quiet operation.
  • Premium Materials: Real CNC Machined Black Anodized Aluminum. Glass Filled Resin Knob Molded over Stainless steel threaded inserts. Stainless Steel and Aluminum Internal supports.
  • Dual Socket Perfection: Although we have shorter arms available, the 3.5" metal arm provides solid support while minimizing vibration. Dual thumbscrews allow you to quickly loosen/tighten the ball and socket joints which allows for unlimited positioning. This arm will not break, bend, or boogie on you. It will stay right where you left it.
  • Optional Anti-Theft Knob: (PATENT PENDING) This arm, although not always necessary, has optional anti-theft features. This can (A) help prevent snatch and grab situations on your motorcycle, SXS, or other similar environments. (B) The ball cannot slip from the socket if properly tightened.
  • Color Swap Compatible: Tackform offers a wide range of anodized billet aluminum knobs. This DuraLock arm is compatible with Tackform's DuraLock knobs, allowing you to customize your setup to match your vehicle. Black knobs are included.
  • Tackform 20 Series: Specifically designed for compatibility with Tackform’s 20 Series Platform, revolving around the 20mm ball and socket system. While compatible with other 20mm products, our parts stand out for their tested durability and engineered load capacities, featuring a safety factor not guaranteed by other manufacturers. Please Note: Not suitable for 25.4mm / 1” / B-Sized balls.

    Awesome product

    I am very pleased with this phone mount for the BMW K1600 GTL. The Chrome does really look good. The phone is safely held by the mount. I am posting a couple pictures which will speak for themselves.

    Super Impressed

    I just installed this mount on my 2023 BMW R1250RT. I'm very impressed with the kit. For my install I wanted my phone as close to the handlebar as possible. I called tackform customer service and a very helpful guy named Nick helped me to understand that in addition to the ball mount there is a dovetail mount the can also attach to the handlebar screw. This allows you to effectively use just 1/2 of the 3.5" arm kit. This is exactly what I wanted. Also, I'd note that the handlebar screw has a recessed hole that the dovetail or ball mount will engage to lessen the risk of anything coming loose if you move the arm around. Overall this is well thought out and the components look great. The kit also comes with one of these rubber "surrounds" (I've seen them on other phone mounts, it's roughly rectangular and can go around the corners of your phone) if you want the phone to be connected with additional security.

    Excellent for my 19 BMW R 1250 RT-P

    Solid kit. This is my third TF mount. I have one on my FLHTP and my Springfield DH as well and I'm a fan. They're so solid and the instructions are always simple enough to follow
