DescriptionThe whole story▼
Ausschließlich für den Renn- und Streckeneinsatz konzipiert, verwandelt der Arrow 71639MI Edelstahl-Krümmer den Abgasstrom der Yamaha YZF-R3 (2021-2026) in ein spürbar schärferes Ansprechverhalten und echte Leistungsgewinne dort, wo es zählt – auf der Rennstrecke.
Wichtige Merkmale
- Renn-entwickelte Geometrie, optimiert für ein verbessertes Ansprechverhalten und messbare Leistungsgewinne an der Yamaha YZF-R3
- Gefertigt aus hochwertigem Edelstahl für herausragende Hitzebeständigkeit und langfristige Haltbarkeit unter dauerhaften Rennbedingungen
- Auslassdurchmesser von 45 mm, exakt auf die Arrow-Slip-on-Endtopfreihe abgestimmt, für eine perfekte Abdichtung und ungehinderten Durchfluss
- Wiegt nur 1,92 kg und reduziert so ungefederte sowie Gesamtmasse des Motorrads für verbessertes Handling und mehr Agilität
- Entwickelt und hergestellt von Arrow, einem der angesehensten Auspuffspezialisten im Motorsport
Verarbeitungsqualität & Leistung
Der Krümmer 71639MI ist so konstruiert, dass er den thermischen und mechanischen Belastungen wiederholter Trackdays standhält. Die Edelstahlkonstruktion widersteht Korrosion, verträgt extreme Abgastemperaturen ohne Verformung und behält ihre strukturelle Integrität über eine komplette Rennsaison hinweg. Die präzisionsgeformte Rohrgeometrie wurde entwickelt, um die Spüleffizienz zu maximieren, und liefert eine breitere, ansprechfreudigere Leistungskurve im Vergleich zum Serienkrümmer.
Um den vollen Nutzen des Arrow-Krümmers auszuschöpfen und das Motormanagementsystem zu schützen, wird nach dem Einbau dringend ein eigens abgestimmtes ECU-Remap empfohlen.
Kompatibilität & wichtige Hinweise
Dieser Krümmer ist ausschließlich für den Rennstreckeneinsatz freigegeben und verfügt über keine Straßenhomologation. Er kann nicht mit dem originalen Yamaha-Slip-on-Endtopf kombiniert werden – für ein komplettes Auspuffsystem muss ein kompatibler Arrow-Slip-on aus der Serie 71831 verbaut werden. Kombinieren Sie diesen Krümmer keinesfalls mit einer Endkappe eines anderen Herstellers.
