The GTYR motor package ‰ÛÒ head, cams and piston ‰ÛÒ are exactly the style of power Kirk likes in his bikes. There is an increase in power but just as importantly, it keeps it in the same delivery as a standard motor. With the GYTR motor package, the power is broadened right across the rev range that allows Kirk to run that higher gear and pull that low rpm now the motor has the grunt and torque to take it.
The use of the Vortex ECU gives the team some adjustability in the power delivery. Using the low, mid and high rpm clicker adjustments, the team can fine tune the power and they can also program maps that increase or decrease the rev limit as Kirk or the conditions require. Many people would think that riders chase as much power as possible and as aggressive as they can make it, but those days are long gone and often teams will reduce the rpm limit and add fuel to give the power give a nice, fat feel and ensure traction is optimised.
The CDR Yamaha Monster Energy Team also have a long relationship with Pro Circuit and have been the exhaust of choice for the team for nearly 30 years now. The relationship is so tight that special exhausts can and have been built for the team in the past, but with a motor package that is readily available, the PC exhaust is now an off the shelf unit and one that works perfectly the GYTR motor combination.
