Following the exchange of Rear suspension, Front suspension also up dating.
Purchase SR400 initial disc compatible Oil attached product.
Clean with all Rose - When trying to assemble it,
Discovery that SpringLength is different.
Initial disc : Spring 445 mm + Color 75 mm = 520 mm
Hyper pro : Spring 490 mm
Although it was assembled as it is in Manual,
Spring + Color thinks Pre-road is too high, in No Color
When assembled, it can be installed with a little pre-road.
The stationary sag also becomes correct as 30 mm according to the Manual value.
The impression of trying on the ride was that the subduction was reduced to the Large width, but the thrust at the time of getting over the step was a little tight.
The attached Oil is # 20 and it is rather stiff and the damping force is high.
Scheduled to lower to # 10 to # 15 at the next Maintenance.

Aufhängungsfedern mit konstanter Steiggeschwindigkeit entworfen von Hyperpro.
Ständig wechselnde Federraten, um der Bewegung der Aufhängung zu folgen. Nicht zu weich und nicht zu hart, und es hat die Kraft, sich in Kurven und beim Bremsen unter schwerer Last auf der Straße festzuhalten..
Es hilft, den Nachlaufwechsel beim Bremsen vor einer Kurve anzupassen, um den Übergang zur nächsten Bewegung zu erleichtern.. Absorbiert kleine Lücken bei der Kurvenfahrt und eliminiert Vibrationen, die den Fahrer stören können..
Im Gegensatz zu einer normalen Feder gibt es keine konstante Federrate, so dass es keine Resonanz gibt..
Mit einer computergesteuerten Werkzeugmaschine wird ein Schussverfahren auf gewickelte Federn angewendet, um winzige Oberflächenkratzer zu entfernen, die zu einer Verschlechterung der Leistung führen können.. Nach der Fertigstellung wird jede einzelne von einem Tester getestet..
In den Niederlanden sind alle Ambulanzfahrräder mit Hyperpro-Federn ausgestattet..

A Fantastic Upgrade for My Honda PC800
I installed these fork springs into my 1994 Honda PC800 Pacific Coast. Due to the large amount of body work that has to be removed it is a lot of work to replace the fork springs. The final results are worth it the Hyperpro fork springs greatly improved both the ride and the handling of the Pacific Coast. These motorcycles are really heavy and if you have one I highly recomend these springs. One caveat to remember if you live somewhere that requires shipment by air the fork oil is not included.

Finally parcel recevied, waited almost 3 months. Spring coils sure thicker & stronger. Especially over hump & uneven road, they just clear smoothly. Great!
