Never raced and never rode hard just leisurely drove on the highway and around the farm. Comes with a full HMF exhaust and HMF Optimizer for high quality performance with a mean sound. Bought it 6 years ago and thought i would use it more but she just sits and gets drove a couple times a year is all. Figured someone else could find a better use for this high performance quad. Could use a set of new front tires but other than that its a solid 4 wheeler. Never had any problems with it. Very snappy/fast quad with plenty of horsepower!
