Vehicle Information
KYMCO Mongoose 90 ATV (2003-2023)
The KYMCO Mongoose 90 ATV, produced from 2003 to 2023, is a youth quad that has maintained a consistent core engine and transmission design. It is powered by an 89cc or 90cc (often used interchangeably) single-cylinder, 4-stroke, SOHC, 2-valve, air-cooled, carbureted engine. Horsepower output saw a minor evolution from approximately 6.3 HP on early models to 6.4 HP on more recent ones. Power is delivered through a CVT automatic transmission with forward, neutral, and reverse gears. Over the years, the Mongoose 90 has received incremental updates rather than distinct generational overhauls. Trim designations like Mongoose 90R (around 2010-2014) and Mongoose 90S (from 2016 onwards) represent evolutionary updates of the core model, with adjustments such as a new ergonomic seat on 2022-2023 models and a shift in the recommended rider age from 12 and older to 10 and older. The braking system (front drums, rear hydraulic disc) and safety features have remained consistent. FAQ:
