Ok, I have good news for the Doo faithful. Non-Doo riders are saying that they have seen the STOCK 600 HO in action and they say it is unbelievable. I guess it runs with the 800s with no problem. These were not Doo guys. They said the 600 HO REV is flat out quick. This is good news! Now it will be Doo and Polaris battling it out for top honors. Those 600 twin motors just keep getting better and better. Now if they do the same thing to the 800 and make it available in all of the models.... that would be awesome. Oh, I'm still waiting on my 1000cc SDFI Twin REV. Are you listening Doo????
