RAISCH TUNING for Street Twin, Street Cup 900cc engine. Our tuning and performance diagrams were all determined on a Dynojet test bench of the latest generation. Triumph indicates its performance on the clutch. However, the performance diagrams are based on the rear wheel performance and therefore cannot be compared 1:1. Between the clutch and the rear wheel, approx. 5 hp and 6 Nm are lost. You can simply add these to the performance diagrams. To make it simple, we have simply stated the effective PLUS power to the standard engine in PS and NM in the descriptions. Triumph states a torque of 80NM and 55 hp at the clutch in the brochure. Our measurements showed 83.8 NM and 58.6 hp. Our Stage 1 KIT offers an immediately noticeable increase in performance. Each additional stage brings a certain increase. But things get really interesting from Stage 3 KIT onwards, where our Raisch Racing cam is used. Our tuning stages have a modular structure. If you want an upgrade at any time, we will install the appropriate mapping free of charge. (Provided the Powercommander was purchased from us).
Our self-developed racing camshafts are "Made in Germany" and are produced from a blank on state-of-the-art CNC machines. (Not to be confused with cheaply manufactured camshafts made from cast material)
A special nitriding steel is used, which is then refined by a hardening process to Rockwell HRC 60 to ensure durability.
