Call Charity A roaring good time. The family resemblance in the Grizzly clan is more than skin deep. You'll find the same superior engineering standards and materials in Grizzly 125: 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.
