Rear spring DR-Z400SM

【HYPERPRO Hyperpro 22053031 Rear Spring DR-Z400SM Suspension】
■Rear Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in accordance with the suspension's movement.
This maintains a state that is neither too soft nor too hard, and also provides the necessary resilience during high-load cornering and sudden braking.
●Front springs come with the required amount of fork oil.
●Optimizes changes in caster during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering and eliminates vibrations that interfere with the rider.
●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that can lead to performance degradation. Furthermore, each spring undergoes a performance inspection by a tester after completion.
●In the Netherlands, Hyperpro's home country, Hyperpro springs are installed on all emergency motorcycles.
