Maxiscoot and MXS Racing proudly present the result of many years of development: the MXS 90cc Cylinder Kit GP2 (46mm stroke) Derbi Euro 3! And, as a matter of course, available for a very good price!

The MXS 90cc Cylinder Kit GP2 (46mm stroke) Derbi Euro 3 has an original patented design and includes a 90cc cylinder (d=50mm / stroke=46mm).

Among the new developments for version GP2 - differently shaped exhaust ports and a newly designed combustion chamber for the cylinder head to boost the performance of the MXS cylinder kit even more. In combination with the right components, but without any additional modification, this kit can reach between 29 and 31hp. The special transfer port design will give you phenomenal torque of 18N·m - even in the low rpm range!

The MXS GP2 90cc cylinder is very powerful at take-off, has impressive acceleration and top speed. Thanks to well-thought-out design and the use of top quality materials this kit is also top-of-the-line regarding reliability and durability (manufactured in Europe).

The kit has to be combined with the MXS crankshaft GP 46mm stroke, the MXS exhaust GP90, a 30mm carburetor (38mm would be ideal), a high-end racing clutch with as many discs as possible, a racing transmission (Bidalot) and a digital inner rotor ignition (Stage6 R/T or Bidalot).

Note:

  • You'll have to mill in the front of your crankcase a little to make room for the connecting rod and the piston base (manual included).
  • It is possible to get even more power out of this kit by using a racing combustion chamber for the cylinder head that is sold separately (can only be run with high-octane fuel); the kit can now easily reach 31 / 32hp.

Improved Transfer Port Design

Forme des transferts optimiséeGas flow volume and speed depend on size and shape of the transfer ports which is usually limited by the stud bolts holding the cylinder in place. With the MXS GP90 90, this limitation was overcome by using a (patented) screw fastening instead of bolts; the transfer ports can now be shaped in the best possible way.
 

3-Part Exhaust Port

Conduit d’échappement en 3 partiesThe MXS GP90 90 has an exhaust port that is divided into 3 ducts, 2 of them usually called boost ports. This increases the port surface and gas emission significantly when compared to "normal" exhaust ports. The 2 bridges forming the boost ports reduce pressure on the piston ring and consequently ensure maximum reliability.
 

Elaborate Cooling System

Un refroidissement étudié avec minutieAn aluminium liner redirecting the flow of the liquid coolant leads to an optimum dissipation of the heat generated by the cylinder. Special attention was paid to the exhaust duct by designing a "water chamber" encircling it. The temperature of the exhaust gases is lowered, and performance consequently improved.
 

Special Combustion Chamber

Plot de culasse exclusifThe MXS GP90 90 cylinder kit includes a standard cylinder head combustion chamber offering a good compromise between acceleration and top speed. In order to increase power, the MXS Racing team developed a special racing combustion chamber for the cylinder head. To avoid rotation when tightening / loosening the spark plug, the cover was equipped with a pin to block it properly during installation.
 

Aluminium Cylinder Head Cover
Original CNC-Milled Design

Couvercle de culasse aluminium fraisé CNC totalement inéditPerfect finishing of even the smallest details thanks to a cylinder head cover cut from one piece and painted a beautiful anodized green. CNC-milling guarantees optimum results.
 

New Patented Fastening System

Système de fixation inédit brevetéThe fastening of the cylinder has been patented and allows for a change in the transfer ports' shape and size never accomplished before. This results in complete freedom in designing the cylinder canals.
