Been a lot of speculation over the last year, especially since the announcement that Cat will be phasing out the Suzuki motors. But now Cat has added their in-house C-TEC2 dual stage direct injection 2-stroke motor to the lineup. Built in their Minnesota plant with domestic parts. A unique new motor design, but take note of the long stroke and all the "extra room" around the cylinders. This motor will no doubt be the basis of an in-house 800cc for next year as all they have to do is bore it out about a cm to get there. Should be interesting to see how this performs. Good to see a 600 class back in the lineup.
They also added a Yamaha 1100 4-stroke to some of their models. So the rumors of a Yamaha deal are also true.
