SPORTEC™ M7 RR derives Metzeler’s experience in Road Racing activities including the “Isle of Man TT” and the “Metzeler Ulster Grand Prix”, featuring completely new profiles, structure materials, compounds and tread pattern.
Our roads are not always perfect like racetracks, we have to face unexpected wet patches, debris or uneven tarmac. Metzeler Sportec M7 introduces a new concept of water drainage and contact feeling thanks to dual-compound on the rear tyre combined with Interact™ technology and high silica compounds.
Tread Pattern Design
The longitudinal groves are interrupted by compound bridges to increase the thrust in accelerations, enhance stability of tread compound and improve wear regularity. These bridges, also, keep the grove wide opened when going under footprint ensuring water evacuation.
In lateral groves, depth decreases gradually towards shoulder area to increase compactness and lateral thrust when turning at maximum lean angle on dry; their width, on the other hand, increases towards shoulder area to guarantee efficient water evacuation at higher lean angle, because with SPORTEC™ M7 RR, on wet, it is possible to reach higher lean angle than with SPORTEC™ M5 INTERACT
Finally, the tread pattern grooves are designed to interact with the compound and structure modifying tyre flexibility, providing agile handling and efficient water evacuation.
Metzeler developed a totally new family of compounds with high to full Silica (SiO2) for Supersport applications.
The key for this real technological breakthrough relays in their exclusive and patented mixing process.
The rear tyre is Dual-Compound with a 40%-20%-40% layout. The shoulders stripe has a 100% silica content that provide chemical grip on both dry and wet surfaces, supported by a harder compound in the substrate that grants the highest levels of stability and steering precision when cornering. This same ‘base’ compound arise in the central portion of the tread covering approximately 45mm in width (with slight difference between sizes) and assuring an elevate mileage capability.
The main function of the profile is to influence the handling behavior of the tyre. The profile of SPORTEC™ M7 RR are directly derived from those used in the Road Racing activity by Guy Martin and all other pilots.
With this kind of geometry, this profile provides an immediate descend into lean from the upright position and agile handling in quick change of direction. The shoulder portion is flatter, providing a 5% larger footprint area which provides a better grip and trajectory precision when leaning.
Sidewall height is also increased by 3mm, providing more torsional flexibility that increases the tyre traction in accelerations and out of the turns.
The radial carcass is made of a special version of Rayon with a high rate of linear density and stiffness. In other words, this structure is much more rigid and capable of maintaining its shape under a higher stress and load strain.
The fiber end-count has then been reduced by 20% increasing the space between a fiber and the next one; this space is therefore occupied by more rubber that enhances the overall dumping effect, providing a better contact feeling and predictability.
Over the radial structure lies the 0Â° steel belt with a 5 zones INTERACTâ„¢ technology to provide progressive behavior at any lean angle. The INTERACTâ„¢ technology is the latest level of evolution of the 0Â° steel belt technology and is an integral part of all METZELER tyre development where steel belt is used.
By Combining the INTERACTâ„¢ Structure with Compound Technology, all the elements of the complex Structure-Belt-Compound blend in the perfect way offering a continuous tuning of the performance over the lean angle of the bike.
The variable string winding tension of the 0Â° steel belt guarantees a progressive pressure distribution, giving tailored solutions to the different needs of every lean angle without any discontinuity in terms of performance.
Sporty Handling: The combination of profiles derived from the Road Racing activities with high stiffness structures delivers an extremely agile handling for a sporty riding style on all roads.
Grip in all Conditions: 100% Silica compounds combined with a special tread pattern gives SPORTECâ„¢ M7 RR the unique capability to keep the sporty riding stile also in cold conditions, wet roads and greasy and grimy tarmac surfaces.
Extended Mileage: 20% more mileage compared to SPORTECâ„¢ M5 INTERACTâ„¢. A dual compound solution on rear sizes allows the use of a specific material on the central slick portion of the tread pattern to increase abrasion resistance and extend the mileage capability.
Note :Even though the photograph shows the tyre pair, the price quoted is only for one tyre and not for pair.
