Description
Low-Mount Exhaust Stage6 R/T 70 – 80 Derbi – Orange
Low-mount Stage6 R/T 70 – 80 exhaust for Derbi, a high-end exhaust from the 2-stroke tuning specialist Stage6 R/T, specifically designed for tuned Derbi models with 70cc to 80cc displacement such as Derbi Senda, Aprilia SX, Gilera SMT, and many other 50cc geared bikes with Derbi engines.
Stage6 R/T 70 – 80cc Exhaust – Design and Performance
It is a classic racing exhaust made of carefully hand-welded thin 0,8mm steel sheet cones. As is normal for high-end systems, the exhaust has a so-called racing finish, which means the body is unpainted and untreated. We recommend to apply grease spray regularly to avoid premature rusting.
Stage6 R/T designed this exhaust specifically for the Stage6 R/T 70cc cylinder kit for Derbi to exploit the full potential of 70 – 80cc setups. Dyno testing confirms strong performance throughout the entire rpm range, with peak power delivered at high to very high RPM. Ideal for engines designed to rev high and achieve maximum top speed.
The exhaust is the ideal complement for 70cc to 80cc racing and high-end cylinders such as the Stage6 BigRacing 77, Malossi MHR Team, or Metrakit Pro Race.
Stage6 R/T 70cc Silencer
The Stage6 R/T 70 silencer matches the exhaust perfectly, both visually and technically. Brushed aluminum body, CNC-machined anodized end caps, and precise “S6 R/T” laser engraving provide high-quality workmanship and a great racing look. Its optimized internal construction also offers a noticeable performance gain compared to the previous version of the Stage6 R/T silencer.
For a clean installation, the combination with the Stage6 exhaust clamp is recommended.
