Yokomo is introducing the all-new YZ-2, a state-of-the-art 1/10th-scale EP 2WD offroad competition mid-motor chassis kit, engineered from the ground-up for today’s racing environment and designed to deliver leading-edge developments to offroad enthusiasts, all while offering a luxurious feel by featuring black-anodized aluminum parts with chamfered edges for select components.

In recent days, offroad racing has seen a shift toward high-grip surfaces; use of artificial turf, carpet and even high-grip dirt has become more and more prevalent. Last year’s World Championships was held on a dirt track where the surface was covered with sugar water to increase the grip.

With these developments in the offroad racing scene, the YZ-2 was designed from the ground-up to perform its best in today’s high-speed, high-grip race tracks.

By employing a super-low center-of-gravity motor mount and gearbox, the YZ-2 has realized an unprecedented weight balance never seen before in offroad racing cars, resulting in dramatically reduction of traction rolls on high- grip surfaces, and improved overall stability of the car.

An innovative steering design where the wiper swing action is directed toward the rear of the car affords a more direct steering response compared to conventional designs. The hard-coated, low-friction anodized aluminum cylinders leads to smoother shock absorbing movements which allows better driving characteristics.

Also, quick alignment adjustments can be made without the need of optional parts by replacing the bushings of the front hub carrier and rear suspension mounts, a quality that can be an advantage in adapting quickly to various track conditions.
