The Metzeler Sportec M7 RR is engineered to empower riders with a sporty riding style who use their motorcycles in all conditions, weather and temperatures. The M7RR is derived from Metzeler's experience in Road Racing, including the Isle of Man TT and the Metzeler Ulster Grand Prix and features completely new profiles, structure materials, compounds and tread pattern.
We all know roads are not always perfect like race tracks, we have to face unexpected wet patches, debris, temperature drops or uneven tarmac. For these uncontrollable variables, Metzeler has introduced a new concept of water drainage and contact feeling thanks to dual-compound on the rear tire combined with Interact technology and high silica compounds.
Tread Pattern Design
The longitudinal grooves are interrupted by compound bridges to increase the thrust in acceleration, enhance stability of tread compound and improve wear regularity. These bridges also keep the grove wide open when in contact with the tarmac, ensuring water evacuation. In the lateral groves, depth decreases gradually towards shoulder area to increase compactness and lateral thrust when turning at maximum lean angle on dry tarmac; their width on the other hand, increases towards shoulder area to guarantee efficient water evacuation at higher lean angle.
For the Sportec M7RR, Metzeler has develop a compound capable of generating chemical and mechanical grip. The development target was to extend the sporty behavior from the ‘perfect or ideal conditions’ of dry warm temperature and regular asphalt to those sudden and unpredictable situations that we all actually encounter when riding on normal roads: wet spots, leaves, temperature drops, debris, holes, etc. Therefore Metzeler developed a totally new family of compounds with high to full Silica (SiO2).
The rear tire is Dual-Compound with a 40%-20%-40% layout. The shoulder strip 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 exists in the central portion of the tread which covers approximately 45mm in width (with slight difference between sizes) and assures an elevated mileage capability.
The main function of the profile is to influence the handling behavior of the tire. The profile of SPORTEC M7 RR Tires are directly derived from those used in the Road Racing activity by Guy Martin and other road racers. This profile provides an immediate dive into a lean from the upright position and agile handling for quick direction change.The shoulder portion is flatter, providing a 5% larger footprint which provides better grip and trajectory precision when leaning. Sidewall height is also increased by 3mm, providing more torsional-flexibility that increases the tire traction in accelerations and out of the turns.
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 the SPORTEC M7 RR the unique capability to keep the sporty riding style in cold weather, wet roads and greasy and grimy tarmac surfaces
Extended Mileage: 20% more mileage compared to the SPORTEC M5 Interact and dual compound construction 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
