2025 TM MX 300 four-stroke motocross bike, a unique handbuilt Italian motocross machine that sits perfectly between a 250F and a 450. The TM 300 four-stroke features KYB suspension, Brembo hydraulic clutch, Brembo front brakes, tank under the seat design, hand-welded frame, and premium Italian craftsmanship. This 300cc four-stroke motocross bike delivers strong roll-on power, less shifting, and smooth controllable torque, making it an ideal choice for vet riders, C-class racers, novice riders, and weekend warriors. Compared to a 250F, the TM MX 300 offers more bottom-end and midrange power, and compared to a 450, it provides better control, less fatigue, and more fun on a vet track. I’m a 43-year-old vet rider, racing C-class / novice, and this TM 300 four-stroke motocross bike allows me to focus on flow, momentum, and smooth riding without over-revving or constantly shifting. On vet tracks, this bike clears jumps easily with roll-on power while still requiring good technique and throttle control, making it one of the most fun motocross bikes I’ve ridden.
