The TM Racing range of 4-stroke engines has become legendary for exceptional power delivery and outright performance and durability. The ability of these engines to perform has become renowned worldwide and for a ‘production’ engine the internal components and materials used are unmatched, many of these components and materials being of a level of quality that would only usually adorn the best of the ‘factory’ engine machinery. With an ever-growing list of results globally, in many disciplines, the 4-stroke range of TM Racing engines has spread to accommodate not only the off-road sector, but now feature in other motorsports. We have witnessed the 450cc engine being adapted for the karting sector where its unique lubrication system, working a twin rotor ‘recovery and distribution’ pump with a lower cavity oil chamber for containment that feeds pumped oil to every part of the engine, has allowed this engine to work with the huge cornering g-forces that karts can create where others struggle to lubricate themselves as the oil swells to one side of the engine. The ‘base’ variant of the 250Fi engine has also been adapted and now sees itself being currently developed in TM Racing’s Moto GP program in the competitive Moto 3 class, this revised engine has already taken Championship Titles. TM Racing’s 4-stroke motorcycle range has seen great success over the past seasons, with the SMX 450Fi machine now having taken multiple Supermotard World Championship titles, it currently leads the way once again and has become regarded as the bike to be riding in Supermotard to get the desired results. A purpose designed Supermotard bike that can be bought as a package, ready to thrive in this discipline where others are generally adapted machines created from other models. The 450Fi Enduro model was also recently adopted and developed to form the TM Racing Rallye bike, the 450 DKR / Rallye, a machine that has taken world championship victories in its class, a great testament to performance and durability in the harshest conditions. The 250Fi and 300Fi variants are also currently setting the world stage alight and have taken World titles in the hugely competitive World Enduro Championship. The latest MX 250Fi / 300Fi 4S machines have been turning heads and impressing riders globally with its sheer performance and handling, a superbly engineered racing machine that is outperforming its predecessor in all aspects and is set to achieve great results. This latest evolution of 250Fi / 300Fi engine features in the EN model also, albeit with revised configurations specific to the Enduro discipline.
