It is finally here! The 50,8 CC twin from MTC and BodySax - the inventor of twin motors in our Bajas.
This motor is a true beast with more that twice the power of a standard RCMK 25,4 CC. Its water cooled billet case allowing the 2 cylinders to sit right next to each other as well as the use of only one flywheel are just some of the basic requirements of being able to fit a twin into a HPI Baja.
The motor uses two standard crank shafts that has been modified and coupled with a special pressure coupling. Additional the crank case is upgraded with larger bearings around this coupling for added durability.
At the rear of the motor the two source coils for the ignition and water pump has been neatly packed in and closed of with a standard pull starter, whereas the front bolts on any standard clutch house just like on a standard motor. The cylinder heads, pistons, crank shafts and carburetors are all standard RCMK superior quality for the maximum performance and easy upgradability or replacement.
The motor comes ready to run including the mechanical driven water pump, capable of delivering 120 L/h of constant cooling for this power plant.
Additionally we have added a primer bulb that injects fuel deeper into the motor for even easier starting of the motor.
This motor is sold in a kit with 1,5 m cooling hose, radiators and 4 Y splitters for correct cooling connections and other hardware to build in the motor (using the build in kit).
It is recommended to be used together with the build in kit consisting of a new tranny plate, a new rear chassis plate and a new lay shaft.
Additional the driver will need an exhaust system. Currently we recommend the Victory ProPipe specially made for this beast.
Choose to drive it with two air filters or just one air filter using the
Air Filter Bridge.
Comes with 1 year warranty."
