THE SPORT TOURING WORLD IS CHANGING: TAKE THE ROAD WITH ROADTEC™ 01
ROADTEC™ 01 is the latest evolution in METZELER touring tyres, with a focus on enhancing grip on wet and low friction surfaces, an increased mileage and a high degree of adaptability to different motorcycles, riding styles and conditions. The contemporary answer to past and future needs.
INCREASED GRIP ACROSS A WIDE RANGE OF RIDING ENVIRONMENTS
ROADTEC™ 01 is able to ensure outstanding grip across an extended range of tarmac, weather and temperature conditions, even going beyond ROADTEC™ Z8 M/O, a test winner in 2015. This means unsurpassed rider confidence when leaning, braking and accelerating, which can be experienced when riding in urban environments, on inter-urban roads and highways. Ensuring a top level of safety on these different conditions is made possible by combining a completely new tread design, new profile and a dual compounds layout for rear sizes. ROADTEC™ 01 tread design features a high number of grooves whose development is transversal to the rotation direction, with the advantage of increasing compound mechanical grip on the ground. The benefit of transversal grooves extends in many different conditions: from riding with cold wet weather on lightweight motorcycles, to longer highway trips during summer on a big touring bike. The tread design as a whole also grants a higher water drainage ratio compared to ROADTEC™ Z8 M/O, thanks to grooves placement and the geometry which has been fine-tuned depending whether the motorcycle is leaning or riding in a straight way. ROADTEC™ 01 profile and dual compound layout play an important role on reaching the target in term of safety, grip and riding confidence: on the rear tyres, the shorter and larger contact patch... Holds a higher number of tread design elements, thereby increasing its efficiency. Includes a higher section of the full-silica shoulder compound, which is capable of delivering the highest chemical grip on wet and low friction surfaces. Dual compound layout on rear sizes features a central stripe with high silica content mixed with carbon black, to increase mileage and stability, while shoulders have a full silica compound providing top notch chemical grip even on more difficult surfaces such as wet and worn tarmac. The central stripe covers approximately 30% of the tread pattern section, with the remaining 70% of full silica compound equally split between the two shoulders. Front tyre sizes use a full silica compound similar to the one on the shoulder of the rear tyres, in order to provide excellent chemical grip in conjunction with the mechanical grip provided by the tread design. The employment of a similar compound between front tyres and rear tyres shoulders also helps providing a homogenous contact feeling to the rider.
EXTENDED MILEAGE & PERFORMANCE CONSISTENCY
ROADTEC™ 01 features an increased mileage (compared to ROADTEC™ Z8 M/O), obtained thanks to the profile, compounds and structural elements. On the rear sizes, the shorter and larger contact works in conjunction with Metzeler patented Interact™ technology to provide three advantages: Reduces the rubbing effect which happens on the tyre surface when the compound slips away from under the contact patch (brush effect). A shorter contact patch means that each point of the tread pattern remains in contact with the ground for a shorter distance at each rotation of the tyre. Helps spreading the stress caused by the weight of the motorcycle and friction forces on a higher surface of the tyre. An important contribution to reach the target mileage is given by the compounds layout which sees on the rear sizes a central stripe with a dedicated formula mixing silica and carbon black. A careful placement of the grooves, following the wear lines generated by the friction between tread pattern and tarmac, allows preserving product performances and benefits throughout the product lifecycle.
ENHANCED PRECISION AND RIDING COMFORT
ROADTEC™ 01 focus on providing riding stability, comfort and handling on naked, sport and touring motorcycles. The employment of METZELER patented INTERACT™ technology, involving a variable 0° steel belt tension layout, reduces movements and vibrations generated by the dynamical forces happening on a motorcycles. These solicitations come from the rider (setting a bend, braking and accelerating, moving the body on the seat...) and the ground (surfaces irregularities, patches, bumps, drains, stone paving...). To counter these movements, the tyre structure has a tension peak close to mid-shoulder lean, enhancing precision when setting up the bend and reducing the movement of the front tyre. A lower tension closer to the edge of the tyre provide a certain degree of flexibility for the tread pattern to copy as much as possible the tarmac micro-asperities, thus increasing grip and contact feeling. A lower belt tension around the central part of the tyre (compared to mid-shoulder area), in conjunction with tread design shaping and geometry, helps absorbing vibrations and bumps, conveying the stress towards the tyre sidewall.
HEAVY WEIGHT MOTORCYCLES (HWM) VERSION
The HWM special version (as in “Heavy Weight Motorcycles”) brings ROADTEC™ 01 performance to a wider range of motorcycles. On these models, HWM version features increased stability by reducing both in intensity and duration the oscillations happening due to road irregularities or steering maneuvers. Distinguishable thanks to a “Weight” icon next to the product name on the tyre sidewall, the increased stability is reached by employing a 2-ply carcass on HWM rear tyres, where standard rear tyres have only 1 ply. HWM front tyre version has the same 2-ply construction as the standard version, but benefits from stiffer carcass material and sidewall construction plus a slightly different compound recipe.
High transversal degree tread design - Increased mechanical grip - More safety when riding also on difficult surfaces
Larger and shorter contact patch - Reduced tyre consumption - Ride longer, ride further
Improved compounds solutions - Reduce tyre consumption. Grip where it matters - Ride longer, ride safer
Tuning of structural elements - Balanced stiffness/flexibility across tyre contour - Stability, precision and predictability in riding
