What can help a fast motor when performance doesn‘t reach the street? Tires are the connection between motor and street, a very important connection. Which tire is the right one for me? Pay attention to the tire size, the speed and weight index listed in your registration - then decide which class you prefer >> Sport for fair weather pilots who like to drive under dry conditions - and then really let it fly... Race for curve fetishists, who love to scrape their footrests. All weather for all season pilots who aren‘t afraid of a little bad weather. Winter for real scooter fans who don‘t let slush and snow keep them from curving around the countryside.
