Details

We proudly present the result of many years of development: the MXS Racing Twin Cylinder Crankcase "Evo", a high-end product designed by MAXISCOOT's racing division MXS Racing – only for specialists and insiders!

We followed a "Zero Compromise" policy when designing this piece. This CNC-machined billet aluminium case (AW6082) contains a 180° twin cylinder crankshaft with 49mm stroke and 95mm connecting rods, balanced by Tungsten counterweights. The crankshaft has larger than standard 25mm journals, the crankwebs are 3mm thicker than standard webs. Together they result in maximum torsion rigidity and stability.

The case was designed for Maxiscoot's flagship cylinder, the MXS GP 90cc.

The kit complementing this MXS Racing twin cylinder crankcase includes 2 CNC-cut anodized green intake spacers that are also made from aluminium AW6062. They allow mounting V-Force 3 reed valves that are meant to be used with this crankcase (not included, order separately). Also included are 2 "3D" intake manifolds with 34.5 - 35mm diameter for 40mm connection plus corresponding adapters.

Installing this twin cylinder case requires some modifications to your engine case to ensure stability and rigidity. Moreover, there has to be made room for the larger than standard crankwebs and main bearings. A detailed machining plan is included.

This product was specifically and exclusively designed for racing; it comes pre-assembled including the following parts:

  • installation guide / machining plan
  • twin cylinder centerpiece MXS Racing, billet aluminium
  • twin cylinder crankshafts MXS Racing 49mm stroke 95mm conrods
  • crankshaft bearings SKF 6005-2RSLTN9/C3VT162
  • intake spacers MXS Racing, billet aluminium, anodized green
  • intake manifolds 3D 34.5 - 35mm / 40mm connection
  • intake adapters d = 40mm
  • small parts and screws
  • gasket kit
