While that move is important to both makers, the bigger news is that Cat will make its own 600cc dual-stage direct-injected motor and it looks to be both simple and clever in design, plus more powerful than Team Arctic’s former 600 (discontinued in 2011), and much more fuel efficient.
In addition to the new 2-stroke and Yamaha’s 4-stroke, Cat has a new naming convention for its engines, implying more power the greater the series number. Plus performance models also get new names too, F is gone and ZR are the new initials.
Here’s how the engines will be listed:- 5000 Series C-TEC4 1100 – this is the older 1056cc naturally aspirated Suzuki 4-stroke that creates roughly 120 horses.- 6000 Series C-TEC2 600 w/dual-stage injection – this is Cat’s new 599cc 2-stroke that creates roughly 123 horses, up from 118 hp in the former 600.- 7000 Series C-TEC4 1049 – this is the Yamaha 4-stroke formerly used only in Yamaha’s Nytro and creating 135+ horses.- 8000 Series 800 H.O. – this is the Suzuki EFI 2-stroke that Cat has used for several years and makes roughly 160 horses.- 9000 Series C-TEC4 1100 Turbo – this is the turbocharged version of the Suzuki 4-stroke 1100. With the turbo added it creates roughly 180 horses. Note: Cat still has two other Suzuki engines, a 499cc liquid for its 500 Sno Pro and F5, plus the venerable 2-stroke 570 fan.How can you get hold of one of the spiffy new Cat 2-strokes?
The El Tigre uses the C-TEC2 600 in its ProCross chassis, but with some major improvements.
