Or, cough up $34,000 for the new Desert Raider and go it alone. Engine size at Dakar is limited to 450cc, so RR UK selected the Italian TM engine as its base (a 530cc version is available for other events). Oil capacity is increased to three liters, the engine is converted to dry-sump lubrication, and a separate oil tank and cooler are fitted. TM’s five-speed enduro gearbox starts out with a wide spread, but this is further increased with a higher fifth gear for reduced engine wear and improved fuel consumption. The engineers at TM are well aware that blocked pumps and injectors are the most common cause of retirement of converted enduro bikes (which is why KTM uses a carburetor on its desert bike despite fuel injection on all its four-stroke enduro and motocross models). So, to avoid such problems, the Desert Raider uses a semi-downdraft Mikuni carburetor, fed through an easy-access filter mounted behind the headstock where it (hopefully) breathes relatively clean air. The final touch is a low-level titanium exhaust, which boosts power and avoids concentrating heat around the engine.
