Higher wear resistance, obtained through a revised land/sea ratio on the rear tire in conjunction with the new tread design, ensures product performance consistency allowing users to enjoy the tire for its entire service life Increased grip on wet roads, with a focus on low friction surfaces (such as city streets and worn tarmac, low temperature), thanks to radial positioning of grooves Rebalanced tire stiffness to allow a better adherence of the rubber with the tarmac micro-asperities, increasing mechanical grip even on lower friction surfaces Increased mileage vs. Roadtec Z8 Interact (up to 10%), thanks to a different footprint shape (larger and shorter) which also enhances motorcycle handling HWM (Heavy Weight Motorcycles) special version to improve performance (see Metzeler website for details)
