What does the 105/150 spring ratio mean?

The 105/150 spring ratio indicates a progressive rate. This means the spring starts softer (105) for initial comfort and then becomes stiffer (150) as it compresses, providing better support for heavier loads and preventing bottoming out.

What is the benefit of progressive rate springs?

Progressive rate springs offer a more versatile ride. They provide a comfortable feel during normal riding conditions and then stiffen up to handle bumps, heavy loads, or aggressive riding, improving stability and preventing the suspension from bottoming out.

Are these springs a direct replacement for stock?

These springs are designed to fit a wide range of motorcycles and are often a direct replacement for stock units. It's always a good idea to compare the specifications and dimensions to your original springs to ensure compatibility.

Product Details

When you're looking to improve the ride on your motorcycle, especially if you're carrying extra weight or riding on rougher roads, a good set of rear springs can make a big difference. These black Progressive Rear Springs feature a 105/150 spring ratio, meaning they offer a softer initial rate for a more comfortable ride and then stiffen up as they compress to handle heavier loads and prevent bottoming out.

These springs are designed to provide a plush performance feel while maintaining stability. The progressive rate design is a smart way to get a spring that works well for a variety of conditions, from everyday cruising to carrying a passenger or luggage. They are a well-built option for many BMW, Honda, Kawasaki, and Suzuki models from the 70s, 80s, and 90s, offering an improved ride without a harsh feel.

If your current rear springs feel worn out or you're looking for a more versatile setup, these Progressive springs are a solid choice. They are a direct replacement for many stock springs, making installation straightforward if you're comfortable working on your suspension.
