Harley Davidson FLSL Slim 18-20 – lowering kit

Do you want your Harley Davidson FLSL Slim 18-20 closer to the asphalt? This lowering kit from Hyperpro gives you exactly the improvement you're looking for - with 15 mm of effective lowering and the comfort and control that only progressive springs can deliver.

Lowering spring kit – the optimal solution

This kit includes lowering springs for both the front fork and rear shock and is the best and most comfortable way to lower a motorcycle. Hyperpro's progressive suspension ensures harmonious balance between the front and rear, giving you better control and a more consistent riding experience.

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 15 mm lower. The progressively constructed Hyperpro spring thus provides both better comfort and an effective, controlled lowering while riding.

This system is superior in both comfort and stability because it preserves the full range of suspension travel and avoids the compromises that mechanical lowering often entails. You get a bike that both feels lower and rides better.
