You'll find the same superior engineering standards and materials in Grizzly 125 and Grizzly 80, too: Nearly bulletproof, torquey four-stroke engines, chain drive, maximum durability and go-anywhere terrainability are what they're all about. Grizzly 125, for riders 16 and older, makes the connection with a fully automatic transmission with reverse, front and rear racks and sealed-drum brakes.
