Mugen MBX7R
 
This is it. It is officially in stock!
Lets have this thread started.:tire:


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.

I love how the instruction manual is just as bad as the manual for the MBX4 back in 1998!

Looking forward to the 7r, got a good feeling about this one. Hopefully see mine in the next couple of days.

Why is there such a discrepancy between the front and rear ride height? 22/28 on the 7r.

It works. The 7t is the same way. Helps weight shift and steering.

The rear arms are different to allow for the clearance the Universals need.
