As a result, owners of older motorcycles can now enjoy tires with Dunlop’s latest technology, including Multi-Tread. Think about that. Tires can have a transformative effect on a motorcycle. Older bikes might well be rolling on older tire technology with less braking and cornering grip, and less compliance than modern tires. The E4 gives new life to older bikes by taking all those evolutionary advancements to the next level with better mileage, more wet and dry grip, less road noise and improved ride compliance, a huge benefit for both older and new machines.
