Description

Details

Thanks to its unique patented construction, the MXS Racing GP2 90cc achieves a displacement of 90cc (50mm diameter and 45mm stroke). The GP2 version features a revised exhaust port shape and a new two-part head design, which once again improves power.
With the right parts and set-up, the MXS Racing GP2 90cc is capable of about 26–28 hp, without any modification. The unique transfer port layout makes for an amazing 18Nm torque, already at low revs!
The MXS GP2 90 offers excellent acceleration, also from stand-still, and great top speed. The workmanship is of course also first rate, e.g. because of the use of premium raw materials and the production in Europe.

The MXS GP2 90 cylinder has to be used in conjunction with the matching MXS GP crankshaft, the MXS GP 90 exhaust system, at least a 30mm carburettor (38mm would be ideal), a high-end clutch, a longer transmission and a digital internal rotor ignition (preferably Stage6 R/T).

NOTE:
In order to provide sufficient space for crankshaft and cylinder base, you will have to modify the engine case (machining plan is included). If you want to squeeze even more power (up to 28–29hp!) out of your cylinder, you can add the competition head cap (available separately), which requires the use of racing fuel, though.
