Quad Skate Chassis




BOSS PRO is the ultimate quad plate: Performance, simplicity and unprecedented warranty.  Designed and tested by skaters for skaters…Top it off by picking a custom colors that fit your style… BE- A-BOSS!

BOSS packs a punch on all levels…By design – Lighter, Faster and Stronger. We have created a plate that has an attitude both in performance and in aesthetics. MOTA Skates is 100% owned and operated by skaters, our philosophy is “There is always room for improvement” as world champions we know this is imperative both at the athlete and product levels.

The BOSS rivals any plate on the market, (size 5.50 194 g. base plate and kingpins, 418g. completely assembled w/out stoppers) Weight has never been our first priority but we were able to achieve arguably the lightest extruded plate in the world while maintaining its integrity. 16 degree trucks make it one of the fastest plates in the world. Speed is measured and generated in different ways. Two of the most important are quickness and power, both very important for all styles of skating. 16 degree plates/trucks allows for unparalleled maneuverability, agility, response, and reaction.  As well 16 degrees trucks enhance power to generate more speed. Both of these significant features allow for better control…be in control–be your own BOSS!
Having confidence in your product comes from quality as well as trusting what product is capable of doing. We have extensively tested BOSS plates for stress fractures, breaking, bending and even malfunctioning. As we said before, there’s always room for improvement, but we go the extra mile to ensure our customer are confident with BOSS plates. Although we are certain you won’t need it we have given our base plate a one year warranty and trucks a lifetime warranty. The warranty is to provide you with unprecedented confidence.

Advantages over its competitors:

  1. 7075 Alloy base plate to prevent twisting or flexing which causes kingpin and tuck issues/breaking.  7075 gives better response and control.
  2. Overall design of the plate is for strength, making the center area square and adding bridges allowed us to reduce weight and retain strength.
  3. BOSS Cast bushings & high performance quad wheels are made the same way. Cast bushing have ultimate return and last longer. It’s important bushings return to their original position with each push.  See our Mota bushings product page for more details.
