The Serpent 750 Evo Natrix is the evolution of the ultra-successful 750. To improve the car we left no stone unturned and tried our ultimate best to make an even better car.
The chassis is made from 3mm 7075-T6 aluminium and has been improved regarding the flex characteristics
It features a new weight bridge, vibration isolated as already used in the big brother, the 989.
For the front we can also use a small adjustable weight, especially useful under high-grip circumstances
In the rear we now have 2 options for the pivot-width. The default position is the same as in the 750, while the wider option is similar to the 748
The new rear suspension is completely new. It features the possibility of a toe change during suspension travel.
Due to the unique design, there is zero binding as well under all circumstances
In the neutral position the toe-change is absolute zero. In this position the rear end acts like the regular 750 rear end.
The higher the link on the upright, the more toe-gain is achieved under compression, resulting in more rear traction under acceleration
The new front arms are open style for aerodynamic reasons. They feature mounting points for an optional heave damper
The 2-speed gearbox is completely new. It is based on the 989 gearbox and bullet-proofed
A much longer ramp for the roller avoiding locking of the second gear even with excessive wear on the shoes
M4 setscrews for gap adjustment to help keeping the gap constant
2 bearings in the second gear bell for better truth of rotation and balance
2nd gear adapter is locked in position to avoid binding and deliver constant performance of engine and gearbox
Newly designed flex cover provides a force free stiffener rod
New shocks and shock towers. These shocks are taken from the 989 and provide trouble-free, low friction action for increased traction
The piston is fixed onto the shaft with a nut. No clipses or shims.
On top of that we payed a lot of attention to the bottom seal. 2 X-rings and a long bushing provide that extra bit of low-friction sealing that keeps the oil inside and the dirt outside
Hard anodized bushings provide a 100% secure positioning of the front upper suspension brackets
As an option the 989 offers a heave-damper setup in the front as well as the rear.
In this way it is possible to change heave adjustments more or less independent of roll adjustments.
As an example it is possible to have a very light roll damping combined with a very high heave damping, something which is not possible with a classic suspension.
The third damper can be used to only alter the damping characteristics without a third spring, but also to add a spring to alter spring rates for heave
The front and rear heave sets are available as an option.
Another option is a side-guard/stiffener for the bodyshell
