Product Overview
Evotech Performance Front Wheel Axle Sliders are designed to provide protection for your motorcycle's front fork bottoms and brake calipers in the event of a fall or slide. This innovative system features a bobbin head that rotates on impact, enhancing durability and impact resistance. The kit includes high-performance engineering materials and is secured by roll-threaded stainless steel spindles for increased strength.
These sliders are compatible with various BMW S1000 and M1000 models. Please refer to the compatibility list in the specifications section to ensure proper fitment for your motorcycle.

Setup and Installation
Installation of the Evotech Performance Front Wheel Axle Sliders is designed to be straightforward. It is recommended to have basic mechanical knowledge and appropriate tools before beginning. Always ensure the motorcycle is stable and secure on a stand before performing any work.
Tools Required:
- Appropriate size Allen keys or sockets for axle nut removal/tightening.
- Torque wrench.
- Thread-locking compound (medium strength, e.g., Loctite 243) - optional but recommended for critical fasteners.
Installation Steps:
- Prepare the Motorcycle: Place the motorcycle on a suitable stand to lift the front wheel off the ground, ensuring stability.
- Remove Existing Axle Nut (if applicable): If your motorcycle has an existing axle nut or cap on the side where the slider will be installed, carefully remove it according to your motorcycle's service manual.
- Insert Spindle: Slide the stainless steel spindle through the front axle from one side. Ensure the correct aluminum spacer and nylon bobbin are placed on each end of the spindle as it passes through the axle.
- Assemble Bobbins: Attach the remaining nylon bobbin and aluminum spacer to the exposed end of the spindle. Secure with the provided nuts and washers. If a hollow spindle nut is included, use it as per the specific instructions for your model.
- Tighten Fasteners: Hand-tighten all components to ensure proper alignment. Then, using a torque wrench, tighten the nuts to the torque specifications provided in the online instructions or your motorcycle's service manual. Apply thread-locking compound if desired.
- Verify Installation: Gently attempt to rotate the bobbins to confirm they are securely fastened but can still rotate on impact as designed. Ensure no components interfere with the wheel's rotation or brake system.

Operating Principles
Evotech Performance Front Wheel Axle Sliders are passive safety components. Their primary function is to absorb and dissipate impact energy during a fall or slide, thereby minimizing damage to critical motorcycle components such as the front forks, brake calipers, and swingarm. The unique design allows the nylon bobbin head to rotate upon impact, reducing the likelihood of the slider snagging on the ground and potentially causing further damage or flipping the motorcycle.
Once installed, no active operation is required. The sliders are designed to perform their protective function automatically in the event of an incident.
Maintenance
To ensure the longevity and effectiveness of your Evotech Performance Front Wheel Axle Sliders, regular inspection and basic maintenance are recommended:
- Regular Inspection: Periodically check the sliders for any signs of damage, cracks, or excessive wear. Inspect the mounting bolts and nuts to ensure they remain tight.
- Cleaning: Clean the bobbins and surrounding components with a mild soap and water solution. Avoid harsh chemicals that could degrade the nylon material.
- Post-Incident Check: After any fall or impact, thoroughly inspect the sliders. Even if they appear undamaged, the internal structure or mounting hardware may be compromised. It is highly recommended to replace any slider that has sustained an impact to ensure continued protection.
- Fastener Torque Check: Annually, or after significant mileage, re-check the torque of the mounting fasteners using a torque wrench to ensure they meet the manufacturer's specifications.
Troubleshooting
Most issues related to axle sliders are installation-related or occur after an impact. Here are some common scenarios:
- Slider Feels Loose:
- Cause: Mounting nuts/bolts are not sufficiently tightened.
- Solution: Re-tighten fasteners to the specified torque. Consider using a medium-strength thread-locking compound.
- Slider is Damaged After a Fall:
- Cause: Product performed its intended function during an impact.
- Solution: Replace the damaged slider and any compromised mounting hardware immediately. Do not reuse damaged components.
- Difficulty During Installation:
- Cause: Incorrect part for model, or improper alignment.
- Solution: Double-check product compatibility with your motorcycle model and year. Refer to the detailed online installation instructions provided by Evotech Performance. Ensure all components are correctly oriented before tightening.
