Millennium Technologies Introduces Polaris 570 Big Bore Kits

Plymouth, WI – June, 2017 – Millennium Technologies, the world leader in Advanced Engine Solutions, is proud to introduce two, brand new, M-Spec bolt-on big bore kit solutions for the extremely popular Polaris 570 models: RZR, Ranger, Sportsman, and Ace. Both Repair and Performance bolt-on kits come complete with everything you need to improve the Polaris 570 engine for an amazing price.

The M-Spec 625 bolt-on big bore kit turns the Polaris 570cc engine into a monster 625cc powerhouse. The 625 M-Spec Kit includes a brand-new Nickel Silicon Carbide (NSC) plated cylinder, an M-Spec design forged +5mm piston kit, and a complete Cometic gasket kit. Power gains of over 10% are typically seen by just bolting on the M-Spec 625 Kit and even more power is available with our M-Spec CNC Ported Head option for an additional $595.95. The NSC plated M-Spec 625 cylinder is extensively modified to not only make it lighter than stock, but also to increase longevity, heat dissipation and power. The M-Spec design forged 625 piston is designed specifically for this application, with special skirt coatings, gas ports, state of the art ring pack, tool steel wrist pins and locks. The M-Spec 625 Kit comes ready to install for a retail price of $599.95.

If a simple repair is required, the M-Spec 578 bolt-on big bore kit is a huge improvement over the stock cylinder and piston at only a small premium over the stock parts. The M-Spec 578 Kit includes a new, slightly modified + 1mm over cylinder, complete Cometic gasket kit and a proprietary M-Spec design forged 578cc piston with special skirt coatings, gas ports, state of the art ring pack, tool steel wrist pins, and locks. The M-Spec 578 Kit comes ready to install for a retail price of $499.95
