Upgrading your motorcycle with a smart screen is one of the easiest ways to bring wireless Apple CarPlay, Android Auto, and GPS navigation to your ride. However, securing your screen safely and stably requires the right hardware.

Because motorcycle handlebars come in various diameters, shapes, and mounting locations, there is no single "one-size-fits-all" bracket. Whether you ride a classic cruiser, a naked streetfighter, or an adventure touring bike with a 12mm GPS bar, this guide will help you choose the ideal bracket for your setup.

📏 Step 1: Identify Your Handlebar Diameter & Mounting Spot

Before picking a bracket, measure the outer diameter of the bar where you plan to install your screen:

• 12mm Thin Crossbars / Accessory Bars:

Commonly found above the instrument cluster on ADV and touring motorcycles (such as the BMW GS series) for GPS placement.

• 22mm (7/8"), 25.4mm (1"), & 28mm (1-1/8") Standard Handlebars:

The standard sizes used on most naked bikes, cruisers, and street motorcycles.

• 31mm Oversized / Fat Bars:

Thicker handlebar sections found on heavy adventure bikes and custom setups.

🔩 Step 2: The 4 Primary Carpuride Brackets Explained

Carpuride offers four primary mounting brackets. Each is engineered for specific handlebar sizes, clearance needs, and security preferences.

🔐 1. BM05 Quick-Release Bracket (BMW-Style Key Lock Security)

The BM05 is Carpuride’s flagship quick-release mounting system designed for universal fitment across all motorcycle brands.

• Key Features:

BMW-style plug-and-play quick-mount system with an included metal security key. It features an anti-vibration design and weather-resistant coating against rain and UV exposure.

• Anti-Theft Protection:

The metal key locks your screen directly onto the bracket. When parked in public areas, you can unlock and detach the screen in seconds to prevent theft.

• Important Compatibility Note:

The BM05 is a standalone mounting solution and cannot be used with BMW's original factory navigation bracket.

⭕ 2. Ring Bracket (12mm – 28mm Handlebar Range)

The Ring Bracket is a versatile, high-value option for standard round handlebars.

• Handlebar Fit:

Fits pipe diameters from 12mm to 28mm using included stackable silicone pads (12mm, 22mm, 25.4mm, and 28mm).

• Dual Installation Modes:

Mode 1 (360° Ball & Extension Rod): Uses an extension rod and dual ball joints to give you full 360° angle flexibility, making it easy to raise the screen above your stock dash.

Mode 2 (Direct Low-Profile Mount): Removes the ball tip and connects the ring clamp directly to the back of the screen, creating a sleek, flush fit close to the handlebar for reduced wind resistance.

🧲 3. U-Shaped Bracket (12mm – 31mm Wide-Range Coverage)

The U-shaped Bracket is designed for maximum adjustment range and oversized handlebars.

• Rubber Cap Rule:

With Rubber Cap: Fits 12mm to 18mm thin bars while providing rubberized anti-slip grip and scratch protection.

Without Rubber Cap: Expands to fit 12mm to 31mm bars, making it the only bracket capable of clamping onto 31mm fat bars.

• Dual 360° Adjustment:

Features a 360° rotatable extension arm and ball head, giving you maximum freedom to position the screen away from brake reservoirs, mirrors, or windshields.

⬛ 4. Square Bracket (12mm – 18mm Thin Bar & Adapter Base)

The Square Bracket is a compact solution built specifically for narrow crossbars.

• Handlebar Fit:

Fits 12mm to 18mm bars using stackable 12mm silicone pads.

• Dual Functionality:

Direct Fixed Mount: Clamps onto a 12mm GPS bar and bolts directly to the back slot of standard Carpuride screens for a solid, shake-free setup.

BM05 Quick-Release Adapter: Serves as the dedicated mounting base to install the BM05 quick-release bracket onto a 12mm thin windshield bar.

🎯 Step 3: Quick Buyer's Decision Guide

Find your riding style and setup below to select the right setup from our Carpuride motorcycle accessories line-up:

🗺️ If you have a 12mm ADV windshield GPS bar:

• Choose the Square Bracket for a fixed, low-profile installation.

• Choose the BM05 + Square Bracket setup if you want key-lock quick-release security on your 12mm bar.

🏍️ If you have standard 22mm, 25.4mm, or 28mm handlebars:

• Choose the Ring Bracket for versatile positioning or flush low-profile mounting.

• Choose the BM05 + Ring Bracket if you frequently park in public and need quick anti-theft screen removal.

🛠️ If you have an oversized 31mm fat bar or complex dash layout:

• Choose the U-shaped Bracket for maximum bar diameter compatibility and wide-angle arm rotation.

⚠️ Step 4: Wire Configurations & Money-Saving Bundle Tips

🔌 Matching Your BM05 Wire Version

If you choose the BM05 quick-release bracket, make sure to select the correct wire configuration to match your screen model:

• 1-wire version: Compatible with W702BS, W502BS, and W602BS.

• 2-wire version: Compatible with W702S Pro, W502S Pro, and W602S Pro.

• 3-wire version: Compatible with W702RS Pro.

⚠️ Note on Cables: BM05 brackets do not include power cables, USB cables, or handlebar controllers by default. The only exception is the 1-wire BM05 bracket for BS models, which includes a USB power cable in the box.

💡 The Bundle Savings Strategy

If you want quick-release convenience, consider the BM05 + Ring Bracket Bundle. In addition to the BM05 quick-release head and Ring Bracket, this bundle includes a FREE Square Bracket. This gives you all the hardware needed to mount your quick-release system on both 22mm–28mm handlebars and 12mm thin GPS bars without buying extra adapters later.
