A wider tyre means: more stability, more grip, and therefore more confidence – that was our goal.And we can say with confidence: goal achieved!

Gibson Powertech – one of the few manufacturers focused on kids’ tyres

We are among the very few manufacturers in the motocross scene who have developed a dedicated junior tyre line. Models like the MX 1.1 FRONT and MX 4.1 REAR were specially designed to meet the needs of younger motocross riders and deliver performance usually found only in professional tyres. 1.1 BIG FRONT and 4.1 BIG REAR. With a well-engineered tread pattern and optimized construction, these two tyres set new standards in the junior segment.
