Motorcycle Suit Knee Sliders: What Are They and Why Do You Need Them?
Introduction
If you’ve ever watched professional motorcycle racers lean into sharp turns at high speeds, you’ve probably noticed the sparks flying from their knees. Those sparks come from knee sliders, a small but crucial part of a motorcycle racing suit. But what exactly are knee sliders, and why are they important for riders—whether you're a racer or just love spirited riding?
In this blog post, we’ll break down everything you need to know about motorcycle suit knee sliders, including how they work, why they’re essential for safety, and how to choose the right ones for your riding style.
What Are Knee Sliders?
Knee sliders are small, replaceable pads attached to the knees of a motorcycle racing suit. They are usually made from durable, low-friction materials like hard plastic or composite compounds designed to slide smoothly against the pavement.
When a rider leans their bike into a corner, their knee naturally comes close to the ground. The knee slider makes contact with the road, allowing the rider to:
-
Maintain balance by acting as an additional point of contact.
-
Gauge lean angle—if the slider touches, they know how far they can push their bike.
-
Protect the suit and knees from abrasion in case of a slide.
Without knee sliders, riders risk grinding their actual suit (or worse, their skin) against the road, leading to costly damage or injury.
Why Are Knee Sliders Important?
1. Safety First
The primary purpose of knee sliders is protection. In case of a fall, they help reduce friction between the rider’s knee and the road, preventing severe burns or injuries. A good slider can mean the difference between walking away from a slide and a painful road rash.
2. Better Control & Confidence
Experienced riders use knee sliders to judge their lean angle. When the slider touches the ground, it gives feedback on how far the bike is tilted, helping riders push their limits safely.
3. Extends the Life of Your Suit
Constantly dragging knees without sliders would wear out the suit’s knee padding quickly. Sliders take the abrasion instead, making them a cost-effective way to protect your gear.
Types of Knee Sliders
Not all knee sliders are the same. Depending on your riding style, you’ll need different types:
1. Plastic Sliders
-
Best for: Track days and casual riders.
-
Pros: Affordable, lightweight, and good for beginners.
-
Cons: Wear out faster than advanced materials.
2. Composite Sliders
-
Best for: Frequent racers and aggressive riders.
-
Pros: More durable, heat-resistant, and longer-lasting.
-
Cons: Slightly more expensive.
3. Metal-Reinforced Sliders
-
Best for: Professional racers.
-
Pros: Extremely durable, can handle high-speed slides.
-
Cons: Heavy and not necessary for casual riders.
How to Choose the Right Knee Sliders
Picking the right knee sliders depends on:
-
Your riding style (street riding vs. track racing).
-
Material preference (plastic for beginners, composite for advanced riders).
-
Compatibility with your motorcycle suit (check attachment mechanisms).
If you’re new to knee dragging, start with basic plastic sliders and upgrade as you gain experience.
When Should You Replace Knee Sliders?
Knee sliders don’t last forever. Replace them when:
-
They’re visibly worn down (less than 50% thickness left).
-
They have deep grooves or cracks.
-
They start feeling uneven or unstable.
Regular inspection ensures you’re always protected.
Conclusion
Knee sliders might seem like a small part of a motorcycle racing suit, but they play a big role in safety, control, and performance. Whether you’re hitting the track or just enjoy aggressive street riding, having the right sliders can make your ride smoother and safer.
