DBO 850 M 2016 Outlander, Max, Renegade, XMR 850 4X4
This kit is specific to extra large tires. 29.5” diameter and larger. The clutch requirements for tires of this size is different. Most often used for mud, soft terrain, and/or ground clearance, it is a different shift calibration requirement. The extra large tires not only have more rotating weight, but a even larger gearing issue resulting from the tires.
This kit includes similar components, but also includes a different secondary spring.
There are instructions in the kit that show you how to set it up for different tire sizes in this range.
The instruction in this kit also show you how to set up the clutches for smaller tire sizes with the stock secondary spring if you ever install smaller tires on the vehicle.
FAQ: I’m a heavy rider and have some heavy 28” tires. I do some mud and want the best performance. I had a different ATV before that needed a secondary spring for heavy 28” tires. Should I order the “M” kit ?
Answer: No, you should not. It is better with the stock secondary spring. Our best test results are shown in the above description of the kits. This new 850 has different engine characteristics than some previous models, as well as very different stock clutch calibration. The optional secondary spring is very sensitive. If you use it when you do not need to it has negative side effects including high rpm and speed loss.
