In a rather surprise and low key announcement, Mugen Seiki’s North American presence (Mugen Seiki Racing), let the cat out of the bag this morning with the release of the MBX7R buggy, an updated and refined version of their Worlds winning MBX7 platform.

The MBX7R kit is based off the World Champion MBX7 platform with many high end improvements in suspension, steering and other areas to create the ultimate 1/8 nitro off road buggy.

Expect firmer details of whats new on the MBX7R, and pay close attention as well to Mugen’s continued strategy of using the Worlds to debut new cars, last time around the MBX7 in 2012.

Update: Mugen concentrated on the making the suspension on the MBX7R even better with new 16mm bodied front and rear racing shocks. These new shocks will improve stability in both bumps and jumps greatly. The bigger bodies’ shocks will make the 7R have less fade during longer runs which means you can drive even harder than ever before. The rear shocks are 4mm shorter and with the use of a new rear shock tower will keep the back of the 7R hooked up and on the ground. The 7R gets a chassis change with the side angle of the chassis changed which creates more strength and a better feeling on all racing surfaces.

The MBX7R gets a re-designed front hub carrier in which the position of the front axle has been changed to a trailing axle position. This will improve overall steering and feeling of the 7R. A new steering ackerman plate with additional steering tie rod holes to have maximum steering adjustability. The front upper suspension arm has been shorten 1.6mm to allow for more camber adjustability and the use of the E0161 spacer between the pillar ball and upper arm.

The drive train of the MBX7R has been changed and improved with the use of a new universal style drive shaft for both the front and rear drive shafts. This will greatly improve the feel of the buggy on bumpy surfaces. The use of the universal will make the overall drive train much smoother and will spin with less friction. New wings mount which will allow the wing to be moved closer to the shock tower to allow for better traction and jumping abilities. The fuel tank gets a re-designed baffle system to increase fuel pick up and to keep the fuel clunk positioned correctly.
