[Description]
Hyperpro's unique low down spring that lowers the vehicle height by changing the rate and adjusting the oil level without changing the free length of the spring. No need to shorten the side stand because it is designed not to sink under the vehicle weight (1G) but to be lowered firmly under the riding condition (1G').
HYPERPRO Suspension Spring
Suspension springs with Constant Rising Rate"" designed by Hyperpro. " The spring rate constantly changes to follow the movement of the suspension.It is not too soft and not too hard, and has the power to hold on even under heavy cornering and emergency braking.
●The change of the caster at the time of braking before a corner is optimized, and it makes it easy to move to the next operation. It absorbs small gaps during cornering and eliminates vibrations that interfere with the rider. ●Unlike normal springs, these springs do not have a constant spring rate and therefore do not resonate. ●The springs are wound by a computer-controlled machine tool and then shot to remove minute surface scratches that can degrade performance. In addition, after the completion, the performance of each unit is inspected by a tester. ●In the Netherlands, the home of Hyperpro, all emergency bikes are equipped with Hyperpro springs.
Performance Comparison by Spring Type
Link System Curved Spring (Hyper Pro) The rate always changes and rises in accordance with the suspension movement (stroke) to support the comfort in the early stage of the stroke and the stepping at the end.It is not too hard and not too soft.
Linear Rate Spring As the rate of the spring does not change during the whole suspension stroke, the spring is prone to be too hard or too soft.It is suitable for stable conditions such as a circuit.
Two-Step Progressive Spring It has two rates that vary with the suspension stroke and compensate for the shortcomings of linear rate springs.The gradual rate change causes discomfort in handling.
■HyperPro The fine (soft) part absorbs small gaps in the road surface and improves the ride comfort. ■Linear rate Stiff springs are uncomfortable to ride, and soft springs cause problems such as bottoming out under heavy load as described in (3).
■HyperPro It gradually increases the resilience and sinks smoothly, which makes sense for riding. ■Linear rate Because it sinks with a constant repulsive force instead of gradually, it does not follow the changing road surface.
■HyperPro Unlike linear-rate springs, these springs can flexibly combine softness and stiffness, so they can hold their ground to the end under high loads. ■Linear rate The reverse of (1).Since it is impossible to combine softness and hardness, the properties of the material tend to be one or the other. The Hyperpro spring is wound at an unequal pitch and has a "constant rising rate", which means that the spring reacts softly to the road in the early stages of the stroke to maintain comfort.The spring rate increases at the end of the stroke for full braking and high speed cornering. In addition, the safety margin at the end of the rate prevents the tire from bottoming out and locking.This "constant rising rate" is set for each model, and the seamless spring rate realizes a smooth ride.

* The image is only for reference. The image shown may differ from the actual product.
Caution
*If the bike is lowered by more than 30mm, a short side stand may be required depending on the condition of the bike.If your vehicle is equipped with a preload adjuster, adjust the lowering to a level where the side stand can be used. *The product in the image may differ from the actual product. *When using the side stand, stop the vehicle on a level surface in first gear.(Because of the lowering, the body will be raised more than stock) *After installation, the balance of the vehicle body will be greatly changed.Be sure to to set the front and rear settings before riding.
*There may be changes in product specifications due to the manufacturer's reasons.
