MMM “B Line” 3in Swingarm Kit

*PLEASE READ*

We are very proud to introduce our newest swingarm to the legendary MMM swingarm lineup; the B Line.  Still made right here in Minnesota from locally sourced 6061 Aluminum stock.  Our goal was to offer a full swingarm upgrade kit for $150 not just an extension kit and we were able to do so by trimming down some of the features available on our flagship line of swingarm kits.  

 First off, we are using raw aluminum stock so the finish with be unmilled, this compromises nothing and cuts down on machining time. Second, it’s only available in the 3in version which still allows you to run a set of 10in super motos (12in wheels will not fit).  Currently it’s only designed to fit the MY1020, KR5V, and theOne.  Our next batch with have the sprocket area milled to fit other motors.

As with all of our other swingarm kits we will include a new rear axle, bottom shock bolt, rear brake bracket, our newest single tool axle tensioners, and our MY1020, theOne, KR5V motor mount kit along with the necessary installation hardware.  

All the same rules apply to this swingarm as with all of our others:  the stock rear shock will not work with this swingarm, you will need to purchase a new rear shock, we have plenty in stock.
