Dunlop expands hypersport range


Dunlop has added to its hypersport range with the SportSmart Mk3 tyre.

The new tyre focuses on dynamic road performance, sitting alongside the recently launched SportsSmart TT which is designed for a mix of road and track use. It is the fifth new hypersport tyre from Dunlop in just two years.

The tyre features innovative new technologies with Dunlop claiming that it ‘tears up the rule book’ for hypersport tyres due to its ability to perform at a high level in both wet and dry conditions.

The SportSmart Mk3 features an all-new Multi-Tread (MT) compound, with a trio of compounds in the rear tyre developed to give riders extra grip in dry and wet conditions.

When compared to the Dunlop SportSmart2 Max in 120/70ZR17 front and 190/55ZR17 rear, the new Mk3 sees a 20 per cent gain in wet grip and a 23 per cent gain in dry grip.

The MT technology comprises a hard wearing central tread compound providing strong traction which also runs underneath the softer shoulder compound to help stiffen the construction. The MT shoulder compound features Dunlop’s all-new wet grip resin, blended with the latest ‘Hi Silica’ and ‘Fine Carbon’ technologies. This exotic mixture is designed to give a fast warm-up time and allow riders to accurately feel the high cornering potential, even in colder weather.

The increased ratio of silica in the compound helps the tyre gain grip and traction on colder days. It has the added benefit of reducing rolling resistance, which improves tyre mileage. The use of fine carbon, which bonds with the polymers in the compound, speeds up the warm-up time. The fine molecules also bond with the road surface more accurately, which increases the contact area under heavy cornering.

The front tyre features the same wet-grip resin with ‘Hi Silica’ and ‘Fine Carbon’ technologies. This gives confidence and stability under heavy braking as well as allowing the rider to better judge the grip levels when turning at speed.

The SportSmart Mk3 brings together acclaimed technologies from other members of Dunlop’s hypersport range. The Dynamic Front Formula builds on the innovation seen on the more track-orientated SportSmart TT, lowering steering effort and optimising turn-in grip. Dunlop’s Carcass Tension Control System (CTCS) controls casing stress distribution. This increases straight-line traction and provides improved feedback with the stability required for a demanding hypersport bike on a challenging road ride.

Dunlop’s Jointless Belt technology (JLB) has been well-proven in the brand’s extensive range of hypersport and sport touring tyres, offering extra casing reinforcement and reducing the tyre expansion at speed. This provides the rider with consistent and predictable feel.

These technologies combine with a new construction shape. Compared to Dunlop’s existing road-orientated hypersport tyre, the SportSmart2 Max, the cross-section of the tyre has a profile that increases the footprint when cornering, but also provides a more consistent contact patch as the tyre wears. This means there is little reduction in performance between a brand new and higher mileage tyre.
