Most of the issues that those earlier models had, like the crappy antifreeze and poor quality thermal switches in the 2015 models was resolved by replaced both parts with better quality parts, so I like that CF Moto has acted to replace a problematic part. Even the shocks that are somewhat of a selling point for the model are being replaced with upgraded ones that are slowly trickling into owners hands. Other main issues are just poor assembly by the dealers, missing a properly torqued A-arm bolt or loose lug nuts as an example.
Up until a week ago, I was a huge fan of the model, and had pretty much eliminated Arctic Cat and Polaris (the others offering a 50" trail model) from my list, and focused squarely on the Zforce 800. I even had one picked out at a nearby dealer and was saving my pennies, waiting for it to be declared a 'leftover' model with the subsequent price drop to accompany that. But after doing some maintenance on my current ride, a King Quad 700, I had forgotten just how much I hate to work on a quad. I was replacing the skid plate and also the front diff fluid, and I just really don't like working on 'em.
So when we have the CF Moto forum veterans that are getting tired of correcting the deficiencies that come with buying a CF Moto, you have to weigh just how much time and effort you want to devote to doing not just the PM work, but other 'fixes' that may not be required by a Rzr or Wildact Trail. I find that my leanings are now in line with Jason, our site admin, who sold his CF Moto for a Rzr 900 due to its refinements. So I did a lot of research on what those 'refinements' were, and let me tell you, he is right. The airbox is tucked up on top of the bed, where it is easy to both service and access. The spark plugs and oil filter both accessible by a panel between the seats ... the list goes on and on, and it shows why they are selling so well. But ... that price !!! Ughh .... so I now have started looking closely at the Wildcat Trail, and it too offers a level of refinement above what you will receive with the CF Moto. Price-wise, its lower than the Rzr 900, so I am going to test fit one next weekend. It is a smaller cockpit than the Rzr, but I can justify that for a cheaper price.
