Gas Gas Ec 300
The GAS GAS EC 300 is a two-stroke enduro motorcycle that traces its roots to the Spanish manufacturer GAS GAS, founded in 1985 in Salt, Catalonia. The EC (Enduro Competition) 300 became a flagship model in their enduro lineup, renowned for its powerful 300cc two-stroke engine and competitive off-road capability. After KTM Group acquired GAS GAS in 2019, the EC 300 was modernized with updated chassis and engine components shared with the KTM/Husqvarna platform, cementing its reputation as one of the premier two-stroke enduro bikes on the market.

What Buyers Should Know
KTM-Shared Platform
The GAS GAS EC 300 shares its engine and chassis platform with the KTM EXC 300, meaning parts availability is excellent and mechanics familiar with KTM can easily service it. This significantly reduces ownership headaches compared to more obscure brands.
Watch the Reeds
A common issue to inspect is the reed valve petals, which can crack or wear with aggressive riding and cause noticeable power loss. Checking reed condition before purchase is a simple but important pre-buy inspection step.
Strong Resale Value
GAS GAS EC 300s hold their value reasonably well due to the KTM connection and strong demand in the enduro market. Well-maintained examples typically depreciate slower than comparable off-brand two-strokes.
