ROADTEC™ 01 is the latest evolution in Metzeler touring tires. With a focus on enhancing grip on wet and low friction surfaces, increased mileage, and a high degree of adaptability to different motorcycles, riding styles, and conditions, the ROADTEC™ 01 provides modern solutions to past and future needs. 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 Belt and carcass tension parameters upgraded to increase stability on rear tires during strong braking Increased mileage vs. Roadtec Z8 Interact (up to 10%), thanks to a different footprint shape (larger and shorter) which also enhances motorcycle handling 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 Metzeler multi-compound rear on selected sizes, with increased harmonization between the different compounds HWM (Heavy Weight Motorcycles) special version available to improve performances on motorcycles requiring them (see Metzeler website for details) Tubeless (TL) (W)-rated for speeds of 270 km/h (168+ mph)
