One of the few Riva brand new ride plates and close loop cooling systems was fit in Greece on an RXT-X along with a Stage III kit and the results were superb. According to tuner Tasos Zisis of Marine Service Kavalas the particular set up resulted on a top speed of 80.5mph A figure that was shown repeatedly on GPS screen. Riva stated that the open loop system is not recommended for the stock engine set up since the intercooler runs too cool therefore it alters a lot the A/FR. Though, it works fine with the stage III kit on the engine. Well, done for the guys in Kavala that made RXT-X owner Nikos very happy with the overall result.
