Ktm 300 Exc Tpi
The KTM 300 EXC has been a cornerstone of KTM's enduro lineup since the 1990s, renowned for its powerful 2-stroke 300cc engine. The TPI (Transfer Port Injection) variant was introduced in 2018, marking a landmark shift from carburetion to fuel injection on a 2-stroke enduro motorcycle, improving throttle response, fuel efficiency, and cold-start performance. It remains one of the most celebrated off-road motorcycles in the world, winning multiple ISDE titles and beloved by amateur and professional enduro riders alike.

What Buyers Should Know
Transfer Port Injection
The TPI fuel injection system eliminates premix and automatically adjusts fuel delivery, making it significantly easier to maintain than carbureted two-strokes. It also improves cold-start reliability and reduces fouled plugs.
Watch the Power Valve
The RAVE power valve requires regular cleaning every 50-100 hours or it can stick, causing noticeable power loss and potential engine damage. Neglected power valves are the most common issue found on used examples.
Strong Resale Value
KTM 300 EXC TPI models hold their value exceptionally well, often retaining 70-80% of purchase price after a year due to high demand and limited supply. A well-maintained example rarely sits on the market long.
