Have had my m70 since February 2017. Handles great no apreshable yaw on breaking or acceleration. Fairly good mpg at 31 to 38, no oil Consumption between oil changes. Just over 11,000 on clock. No warranty issues have come up. Replaced 1 pusher tire,1 e brake cable.installed 2 seven inch spots, and police seat. Raised handlebars 2 in. I learned the way to minimize yawning is proper e brake, and sidecar brake adj, assuming proper assembly at dealer. I also changed lean out from 3 degrees to 0 degrees to fit my riding preference.
