This Novarossi Mephisto 4 Port .21 Off-Road Nitro Engine features a front Steel Bearing and a rear Ceramic Bearing. Novarossi also offers this engine with front and rear Steel Bearings (NVRMEPHISTO.21OFF/A).
- Rear cover: The rear cover presents a round shape to optimize the filling and reducing the dead spaces. the steel plate is to reduce friction and to expand the lifespan of the conrod.
- Sleeve: The sleeve has 4 transfer ports to supply a linear power output and to keep fuel consumption low.
- Crankshaft: The crankshaft is manufactured with a larger bore intake to increase the mixture flow and has a special shape to optimise gas-flows in the engine. The durability has been significantly improved with the DLC coating.
- Combustion chamber: The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.
- Rear ball bearing: The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.
- Conrod: R4/18 conrod, redesigned and made with a special aluminum alloy that allows it to have a high resistance while maintaining the lightness and performance of the previous R4/17.
- Carburetor: The three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling.
- Cooling head: Redesigned to improve the flow of air and thus increase cooling and ensuring an optimal center of gravity.
- 51007 (EFRA 2135) tuned pipe & 41021 manifold: The 51007 EFRA 2135 tuned pipe, made in collaboration with Hipex, coupled with manifold 41021, allows to maintain the same consumption of the kit 9901/41021 increasing further performance.
