Dirt Bike Magazine tests the 2021 TM 300en two stroke. For 2021 TM added a sixth gear to the transmission, some minor frame changes and the U.S. importer now has more upgrade options for each customer to personalize their machine. TM USA does offer a base model, but the version in this test features upgrades available straight from the factory, or if you already have the bike, these items are also available through your local TM dealer.The engine is equipped with an electric power-valve system, electric starter with a manual kickstarter backup, counterbalancer on the crank, Keihin carburetor, VForce 3 reed cage, HGS exhaust system, hydraulic clutch using Brembo components and a 6-speed gear box using a gear sensor that changes mapping designed specifically for each gear. We have seen similar systems on four-stroke MX models, but this might be a twostroke first. All these items come standard, and the unit here has an optional radiator fan kit and racing wiring harness with a handlebar-mounted map switch that allows on-the-fly adjustment between two pre-pro-grammed factory maps, but internally, the powerplant is OEM.The first question you are probably asking is, why are we wasting time testing a 2021 TM 300EN carbureted version and not testing the fuel-injected model? Well, you might be surprised, but not everyone is sold on the fuel-injected two-stroke philosophy. One of those people being TM USA’s importer, Ralph Schmidt. He claims to sell nine carbureted units to every one TPI model. He also stated that because some European manufacturers no longer offer carbureted models, their riders are turning into loyal TM customers. Let us reassure you, the carburetor is alive and well, and the 2021 TM 300EN proves it.Bottom line is, this machine is a great foundation for any type of offroad riding or racing. Yes, you need to dial it in for your specific needs, gearing and suspension, but it has all the tools you will need—smooth power delivery, high-quality components like a Kayaba fork, Ohlins shock, Brembo hydraulic clutch, Nissin rear brake, V-Force reeds, Excel rims and machined billet-aluminum parts throughout the machine. Add some custom options, like a larger fuel tank, radiator fan kit and racing ECUs to the package, and things just get better. TM is a small company in Pesaro, Italy, but the 2021 TM 300EN is a huge player in the 300cc off-road world.
