This is the standard adjustable clutch kit that is used for stock and oversized tires up to and including all 28” tires and applications. This kit offers improved acceleration and response, as well as adjustability for tires within the range specified. There is no loss of top speed from the kit. The included “set up guide” shows you how to set up the kit for your application.
There are instructions in the kit, as well as the part number for the optional secondary spring (DPSS-B/V) to convert this kit to the “M” kit if you ever install 29.5” or larger mud tires.
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.
