Super Ware, endlich erreiche ich mühelos die eingetragene Endgeschwindigkeit, ausserdem habe ich eine etwas höherer Reichweite pro Tankfüllung. Fazit: Sehr zu Empfehlen.

Shipping was very quick. Didn't have to tune bike. Just replaced the stock filiter. I like that it still uses the stock cover because I park my bike outside in a parking lot. Nobody will unbolt my filiter and run away with it. Bike sounds slightly cooler. I think it runs a bit hotter, but hard to tell.

Bike performs better with this filter fitted. Breathes easier, smoother ride through all the gears, better pick up from the throttle. Glad I put it on, and of course it doesn't change the aesthetics of the bike, hidden under the original cowling.
