As he puts it:\u003c\/p\u003e\n\u003cp\u003e“Over 25 years working side by side, pushing the limits and achieving major victories like the 2012 World Championship, three European titles, and many other prestigious international wins.”\u003c\/p\u003e\n\u003cp\u003eAnd now, in 2025… we’re raising the bar once again!\u003c\/p\u003e\n\u003cp\u003eIntroducing the new Ultimate R36 engine, the result of years of development between Robert and our technical team. This engine represents the perfect balance: smooth, easy to drive, and with fuel efficiency that will blow your mind.\u003c\/p\u003e\n\u003cp\u003eRobert says it best:\u003c\/p\u003e\n\u003cp\u003e“I’m truly proud of this project. The R36 is super smooth and linear, and with the Supersonic 2141 pipe, the on-track feeling is just insane. And the fuel efficiency? Out of this world!”\u003c\/p\u003e\n\u003cp\u003eThe Ultimate Combo?\u003c\/p\u003e\n\u003cp\u003eThe new R36 comes paired with the Supersonic 2141 exhaust with ceramic treatment, our great FlowMax venturi, our renowned AIRMAX air filter, and a custom exhaust mount — all designed to squeeze out maximum performance.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eENGINE\u003c\/p\u003e\n\u003cp\u003eManufactured by the prestigious O.S. Engines, the R36 is based on the square-stroke Speed B21, evolving from the previous MXS with key upgrades: new intake and exhaust timing, a redesigned backplate, and an optimized crankcase.\u003c\/p\u003e\n\u003cp\u003eIt features a sealed combustion chamber with an O-ring for flawless sealing and maximum linearity. And yes — the FlowMax venturi is included, making this a truly elite package.\u003c\/p\u003e\n\u003cp\u003eThe result?\u003c\/p\u003e\n\u003cp\u003eA power curve that’s smooth yet explosive when needed, delivering responsive and consistent performance through every turn — and one of the best idles on the market.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eCOOLING HEAD\u003c\/p\u003e\n\u003cp\u003eThe 8-fin head is the same proven design found on our current engines, but with a unique look that makes it stand out. With a low center of gravity and an airflow-optimized shape that directs cooling straight to the glow plug, it ensures more stable carb tuning and idle — even under extreme conditions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eCARBURETOR\u003c\/p\u003e\n\u003cp\u003eThe O.S. 21 J3 carb has been refined with a custom high-speed needle holder featuring head-style fins to help maintain a cooler, more stable temperature — boosting both performance and efficiency. Unlike the original OS carburetor, its high-speed needle holder was redesigned for a better refrigeration of the fuel flow into the carburetor, lowering the temp of the carb, and consequently it is more stable with a great idle stability, improves fuel mileage and overall engine performance.\u003c\/p\u003e\n\u003cp\u003eThe carb comes with the Dust Cover Ring from Ultimate Racing. This ring has been designed to guarantee the best sealing of the carburetor.\u003c\/p\u003e\n\u003cp\u003eBesides this, the uniball joint of the carb slide was also modified with two stoppers instead of one. With this new modified design, you can easier adjust the angle of the uniball joint without having to disassemble the engine.\u003c\/p\u003e\n\u003cp\u003eFor those who love to fine-tune, this carb delivers ultra-precise adjustments, ideal for expert drivers.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eBACKPLATE\u003c\/p\u003e\n\u003cp\u003eCNC-machined from Swiss 7075-T6 aluminum, the new backplate features larger cutouts to improve fuel flow and boost power.\u003c\/p\u003e\n\u003cp\u003eIts smart design allows for safe removal — even with the piston at bottom dead center — without any special tools or risk of damage.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eCRANKSHAFT\u003c\/p\u003e\n\u003cp\u003eCoated with DLC and equipped with two tungsten counterweights, the crankshaft improves rotational inertia, delivering smoother mid-range response and more progressive throttle feel.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eBEARINGS\u003c\/p\u003e\n\u003cp\u003eAt the rear, an original O.S. ceramic bearing.
