Lowering spring kit – the optimal lowering solution

This is a complete spring kit that includes lowering springs for both the front fork and rear shock. It is the best and most comfortable way to lower a motorcycle, as Hyperpro's progressively built springs ensure harmonious balance between the front and rear and improved suspension in all riding conditions.

Important things to know about lowering with a spring kit:
When lowering with a spring kit, the seat height does not change in an unloaded state, as the springs must have the same length as OEM in order not to sit loosely on the shock absorber. However, in a loaded state – when the rider is sitting on the motorcycle – the seat height will be the specified 20 mm lower. The progressively constructed Hyperpro spring thus provides both better comfort and an effective, controlled lowering while riding.

This system is superior to traditional lowering methods because it preserves the motorcycle's geometry and suspension characteristics, while giving you the desired lowering exactly when it matters – when you're on the machine.
