Due to the problems commonly associated with tuning Rotax Max Engines, Motronix has created the JetSpeed range of products to help. The JetSpeed eliminates the need for a PC or Weather Station as it is an all-in-one portable device designed to quickly and accurately calculate the carburetion needs of the Rotax Engine. All you literally need to do is turn it on and it will calculate the correct jet size for both the K27 and K98 needles in seconds displaying it simply with an LED.

Available for Rotax Max Junior and Rotax Max Senior engines.

After testing done by the Kiwi Kart Factory Team throughout the 2011 Rotax Max Challenge Series,
it has been concluded that the team could no longer do without the Motronix Jetspeed System.
After using this unit the team said "gone are the days of chasing your tail trying to find the right tune,
now we just flick the switch, select the jet, and get on with racing. Since we started using this unit we have had no more popping or banging, it really is amazing that such a simple to use device could be so reliable. We won't be going rotax racing without it."
