20mm lower front and rear springs in black for models with ESA. 

A spring is an essential part of the motorcycle. It has to keep the motorcycle, with rider, passenger, luggage in the correct riding position and keep the wheels in contact with the road, while shifting up, while braking, while cornering, on the straight, in short, in every circumstance.

During those circumstances, the need of the rate of the spring in ideal situation is changing continuously.

Therefore Hyperpro designed the rising rate progressive springs. Not only for the front fork, but also for the rear suspension. Using the correct springs gives you better a balance and control, a shorter and more controlled braking distance, an improved bump absorption, better load capacity and the possibility to adjust the ride height of the bike.
