On to the newest bike, the 300Fi MX/EN. According to US TM rep Ralf Schmidt, unlike many 250/300 two-strokes where nearly everything is the same on bikes from the same brand, there are very few interchangeable parts from the TM 250Fi and 300Fi. He points this out to drive home the point that, sure, a 300cc bike isn’t much different size-wise than a 250, but TM set out to make a whole different machine than the 250, and 450 for that matter. The cases, transmission, and most of the engine is different. According to Schmidt, TM tested many engine sizes and found that a 300cc four-stroke (rather than the more popular 350cc size) worked best. Also, according to new rules for the FIM World Enduro Championship, the premier class (now called EnduroGP) includes all motorcycles 250cc to 450cc, thereby including the 300Fi.
