DescriptionThe whole story▼
Derselbe Force-Evo-Dämpfer, 400 statt 350 mm Gehäuse. Diese fünfzig Millimeter gibt es aus einem Grund: den Dezibelwert so weit zu senken, dass er auf Strecken mit harter Grenze durch die Abnahme kommt. Wenn Deine Trackdays regelmäßig am Lärmmessgerät enden, ist das die Artikelnummer, die das löst.
Key Features
- Force-Evo-Dämpfer im längeren 400-mm-Gehäuse, als Gruppe mit Hitzeschutz.
- Die zusätzliche Gehäuselänge ist eine Lärmmaßnahme, keine Stilfrage – mehr Volumen heißt mehr Dämpfung.
- Titangehäuse mit der charakteristischen Sicke, die in die Carbon-Endkappe ausläuft.
- Titanhülle, perforiertes Innenrohr und innere Endkappe.
- Passt an Sparks R9-Krümmer GYA8801 und GYA8802.
- Gefertigt von Spark in Mantua, Italien.
Verarbeitung & Material
Konstruktiv ist das der 350-mm-Force-Evo mit längerem Körper: derselbe Titanaufbau, dieselbe ins Gehäuse geprägte Sicke, dieselbe Carbon-Endkappe. Die Sicke ist da, weil eine dünne Titanhülle Versteifung braucht – und fünfzig Millimeter mehr Gehäuse vergrößern die Spannweite, die sie überbrücken muss. Einer der stillen Gründe, warum Spark das Merkmal behält, statt es für eine glattere Fläche fallen zu lassen.
Der Hitzeschutz gehört zur Gruppe. Am längeren Gehäuse deckt er mehr Rohr ab, was zählt, wenn Deine Rasten hoch sitzen.
Leistung & Klang
Mehr Länge kauft Dämpfung. Für das 400-mm-Gehäuse an der R9 nennt Spark keinen Wert, aber das Muster über das Programm hinweg ist eindeutig: An der Kawasaki ZX-4RR bringt der Wechsel vom Standard-Force-Evo zur längeren Version den Wert von 105 dB auf 98 dB bei 7.500 U/min. Erwarte hier ein vergleichbares Verhältnis – und frag uns nach der R9-Messung, wenn eine konkrete Zahl darüber entscheidet, ob Du fahren darfst.
Passform & Kompatibilität
Für Sparks R9-Krümmer GYA8801 und GYA8802. Prüfe vor der Bestellung, ob Verkleidung und Rasten am längeren Gehäuse frei gehen – bei manchen Trackday-Aufbauten liegt genau dort ein Halter. Die kürzere Version desselben Dämpfers ist GYA8801ST.
Straßenzulassung
Keine. Leiser heißt nicht legal: Diese Dämpfergruppe hat keine EG-Betriebserlaubnis und gehört auf die Rennstrecke.
