2Pcs Swing Arm Chain Guide Slider
These two swing-arm sliders provide a low-profile shield for the chain path on compact dirt bikes. With a compact footprint measuring 80 mm long and 23 mm wide, they fit neatly against the swing arm while leaving sufficient clearance for the chain and sprockets. The dual-pack is suitable for XR50, CRF50, SSR, and other 110–125cc pit bikes, offering an affordable upgrade to reduce chain derailment and swing-arm wear during aggressive riding. Installation typically requires basic fasteners and alignment checks. Regular inspection helps maintain proper fit and optimal protection under heavy use.

The chain roller tensioner helps maintain correct tension, while the chain slider prevents derailment and wear on the swingarm, and the iron guard guards the gearbox and sprockets. Ensure model compatibility before installation; basic tools are typically sufficient for mounting.

This slider protects the swing arm, sprockets, and chain path under rough riding and jumps while enabling customization in color or finish.
Buying Guide
When choosing a dirt bike chain slider, riders should assess several factors to ensure proper fit, performance, and value. The following considerations cover multiple perspectives, from entry-level maintenance to performance-focused upgrades.
- Compatibility and model mapping: Confirm engine size and model compatibility (50cc–212cc ranges are common). Some products list specific models (XR50, CRF50, SSR, TaoTao, Coolster); verify your bike’s make and year before purchase.
- Material and construction: Sliders come in nylon, plastic, rubber, metal guards, or combinations. Nylon and plastic options are lightweight and flexible; rubber offers impact resistance; metal guards provide rugged durability but may add weight.
- Size and fitment: Pay attention to dimensions (for example, 80 mm length and 23 mm width) and mounting points on the swing arm. A poor fit can cause chain interference or insufficient protection.
- Protection scope: Consider whether the slider protects only the swing arm or also guards the chain path and rear sprocket area. Some sets include chain tensioners or guards for extra coverage.
- Installation and tools: Some items require only basic tools, while others may need drilling or alignment adjustments. Check whether hardware is included and if professional installation is advisable.
- Maintenance and inspection: Regularly inspect sliders for wear, cracks, or loosened fasteners. Misalignment can lead to chain rub or sprocket damage.
- Performance impact: A well-installed slider can reduce derailment, chain slap, and swing-arm wear, contributing to longer drive train life and smoother operation on rough terrains.
- Aesthetic and color options: Some models offer color choices to match bike schemes, which can be a consideration for riders prioritizing appearance as well as function.
- Availability and price: Availability may vary by brand and region. Compare total cost, including any required hardware or upgrade components, to ensure good value over time.
- Future maintenance: If your riding includes frequent jumps or aggressive riding, prioritize sturdier options with proven wear resistance and easier replacement parts.
Across these options, buyers should balance the need for effective chain protection with ease of installation and model compatibility. No single product fits every bike, so use the buying guide to identify which features matter most for your particular dirt bike setup and riding style.
