A zealous endorsement from the Italian companies? website:
?New Colossus Bandit for application in motocross opens a new frontier in the development of off-road sport. A tire fully formulated with the latest technology to overcome the outdated designs cross. The Colossus Bandit has great visual impact, 20 mm grooves with high capacity self-cleaning mud and run smoother on firm stretches, improving performance in wagons and on soft soils. Our tests on prototypes showed a gain of up to 20% acceleration and speed on firm, high traction mud terrain in places.?
