Recently we had the opportunity to test three R&D parts specifically designed to enhance the overall performance of Ultra 300X. Initially we tested and made two speed runs of a Kawasaki Ultra 300X and we recorded a top speed of 67.8mph at 7.750rpm (on GPS) although the impeller had a mild damage as well as the one static vein of the pump. Then we replaced the stock ride plate, intake grate with the new R&D ones and additionally we fit an R&D Speed-up module. When we tested the craft we recorded consistently a top speed of 72.7mph at 8.280rpm half an hour after we tested the complete stock craft. The R&D equipped Ultra 300X was faster in acceleration and clocked always 72.7mph at 8.280rpm consistently without keeping the throttle wide open for long time. It is amazing what you can do with a few good bolt-on parts in the first place nowadays. The particular test would have been able to be performed without the valuable help and support of Champions store in Athens, Greece and the cooperation of R&D USA.
