Suzuki Savage LS650 Rear Suspension Replacement Part Guide

The Suzuki Savage LS650 (also known as the Boulevard S40) is a popular budget-friendly cruiser. Its rear suspension, however, is often criticized for being too soft and inadequate for heavier riders or two-up riding. If you're looking to replace the rear suspension on your Savage, there are several aftermarket options to improve ride quality and handling. This guide covers the key considerations, available part types, and factors to help you choose the right replacement.

Understanding the LS650 Rear Suspension

Stock Shock Specs and Limitations

The stock rear shock on the Suzuki Savage LS650 is a single coil-over unit with minimal adjustability. It has a spring preload adjustment but no adjustable damping. The spring rate is relatively light, optimized for a lightweight rider. Many owners find the stock shock bottoms out easily, leading to poor handling and comfort. The stock shock length is approximately 13.5 inches (343 mm) eye-to-eye.

Signs You Need a Replacement

Common indicators that your rear suspension needs replacement include: sagging, excessive bottoming on bumps, a bouncy ride, oil leaking from the shock, or inability to adjust preload to achieve proper ride height. If the shock is more than 10-15 years old, internal wear is likely.

Types of Rear Suspension Replacement Parts

OEM Replacement Shocks

Genuine Suzuki replacement shocks are available, but they replicate the same soft performance. Unless you want to maintain original specs, OEM is not recommended for improved ride quality.

Aftermarket Progressive Rate Shocks

Progressive rate springs provide a softer initial compression for small bumps and a stiffer rate for larger impacts. Many riders opt for shocks from brands like Progressive Suspension, Bursig, or Hagon. These offer better damping and often have adjustable preload and rebound damping.

Coilover Conversion Kits

Some aftermarket kits allow you to convert the LS650 to a dual shock setup, but this is less common and requires fabrication. Most stick with single shock replacements.

Air Shocks

Air shocks are an option for adjustable ride height and spring rate. However, they require an air pump and can be less reliable. They are not common on the Savage.

Key Factors When Choosing a Replacement

Rider Weight and Riding Style

Your weight and how you ride (solo, two-up, touring, or aggressive cornering) determine the spring rate needed. Most aftermarket shocks come in different spring rates – select one matched to your weight plus gear. Some brands offer custom spring rates.

Shock Length and Ride Height

Aftermarket shocks may vary in length. A longer shock raises the rear, affecting handling and seat height. Standard eye-to-eye length is 13.5 inches, but some prefer 13.0 or 13.75 inches. Measure your current shock clearance before ordering.

Adjustability

Basic replacements have only preload adjustment. Higher end shocks add rebound damping adjustment, and some also offer compression damping. For street riding, preload and rebound are sufficient. If you ride aggressively, consider a shock with both rebound and compression.

Build Quality and Materials

Look for shocks with a polished or chrome body for durability. Internal components should use quality seals and oil. Shocks from reputable brands like Progressive, Hagon, and Ohlins (though expensive) are proven.

Popular Aftermarket Options for LS650

Progressive Suspension 12-1110

This is a direct replacement with progressive rate spring and preload adjustability. It is a popular upgrade for its improved comfort and handling. It maintains stock ride height. Price is moderate.

Hagon Shocks

Hagon offers a custom-made shock for the LS650. You specify your weight and riding style, and they set spring rate and damping accordingly. They offer both standard and remote reservoir versions. They are known for quality and reasonable pricing.

YSS Shocks

YSS makes an affordable line of shocks with adjustable preload and rebound. Models like the MZ series are available for the Savage. They are a good budget option.

Ohlins S46 Series

For top-tier performance, Ohlins makes a rear shock for the LS650 (S46DR1). It features adjustable preload, rebound, and compression. Expensive but excellent for spirited riding.

Installation Tips

Tools Needed

Basic tools: socket set, wrenches, torque wrench, and a jack or stands to lift the rear wheel. The shock is secured with one bolt at the top and one at the bottom.

Steps

1. Place the bike on a center stand or lift so the rear wheel is off the ground.
2. Remove the seat and side covers for access.
3. Unbolt the top and bottom shock mounts. Support the swingarm if necessary.
4. Remove the old shock.
5. Install the new shock with new bushings if provided. Torque bolts to manufacturer specs (usually around 30-35 ft-lbs).
6. Adjust preload to your desired sag.
7. Test ride and adjust damping if applicable.

Final Recommendation

For most LS650 riders seeking a significant improvement over stock, a Progressive Suspension 12-1110 offers the best balance of cost, performance, and ease of installation. For riders who want a custom-tailored experience, Hagon shocks are an excellent choice with their personalized spring rates. The stock shock is underdamped and undersprung, so any quality aftermarket replacement will be a noticeable upgrade. Always ensure the shock length matches your intended ride height and that the spring rate suits your weight. Avoid cheap unbranded shocks, as they often fail quickly. Invest in a trusted brand and enjoy a more compliant and stable ride.
