Vehicle Information
KTM 250 EXC Dirt Bike (1989-2023)
The KTM 250 EXC, produced from 1989 to 2023, is a renowned enduro motorcycle known for its continuous evolution in engine technology, chassis design, and various trims. This model line includes both two-stroke (EXC) and four-stroke (EXC-F) variants, each with distinct development paths. The nominal engine displacement has consistently been around 249cc to 250cc across the range. Significant generational shifts mark the 250 EXC's history. For two-stroke models, a major transition occurred in 2018 with the introduction of Transfer Port Injection (TPI) fuel injection, replacing carburetion for improved efficiency and smoother power delivery. The four-stroke EXC-F variant was introduced around 2006-2007, featuring a DOHC engine and later incorporating fuel injection around 2010-2011. Chassis and suspension also saw major overhauls, notably with the PDS rear suspension in 1999, and lighter frames and updated components in 2008 and 2017. Special editions like the "Six Days" trim, introduced around 2012, offer premium components for both two-stroke and four-stroke versions. FAQ:
