NEW METZELER RACETEC – WITH INTERACTTM TECHNOLOGY

New Metzeler Racetec – With InteractTM Technology

Advances in evolution are something you can’t stop, above all in the motorcycle racing world. Tyres must lead the process of evolution in order to match the increasingly sharp precision and demanding behaviour of the latest racing bikes. Metzeler’s answer is based on technology: the new Racetec adopts INTERACT TM technology, the latest evolution of the patented 0° steel belt. The main target of this new development was the desire to make one step forward in the PURE LAPTIME project, designing what we call the new PURE RACETIME project: regardless the skill of the rider, the aim is to shave seconds not only off his best lap times but also the overall race times, thanks to a very constant performance all the way to the end. The New Racetec design is tremendously effective, and it’s cool to look at. It is characterized by the concept of controlling the distribution of land/sea ratio from the crown to the shoulder, following an optimized tread distribution (patent pending). It makes the ride more linear at every lean angle, reducing the tread’s influence on the tyre’s behaviour on track and reducing any overheating effects, to ensure maximum duration of full-on performance.

Structure: INTERACT TM technology The new winding process of a 0° steel belt reduces the contribution made by belts and carcass to stress resistance all along the profile. Lower tension in the crown area creates more flexibility and the tyre can adapt itself better to the road surface, enlarging its footprint. High steel belt winding tension in the shoulder area ensures maximum and uniform pressure on the contact patch: the trajectory is therefore always precise, without any deviation.

 

New Rear Tread Pattern:  4 Compound variants are available (3 for race and 1 for street usage). Each of them precisely tuned for specific weather and surface conditions, ensuring the rider can find the best solution, whatever the temperature and tarmac conditions.

NEW METZELER MOTORCYCLE TYRE – ROADTEC Z6 INTERACT

PRODUCT CHARACTERISTICS

ROADTEC Z6 INTERACT represents Metzeler way of innovation. Instead of pushing on a single element of the tyre like the compound which is then subjected to wear, Metzeler established that is more effective to improve the whole tyre system. Making the tyre elements interact to the maximum level means improving the interaction between the tyre and the ground, the tyre and the bike, the tyre and the external environment. This is the key of the new INTERACT technology. ROADTEC Z6 was perfection, ROADTEC Z6 INTERACT is the evolution, the fine tuning which guarantees it to be the perfect tyre for the new generation of bikes and riders.

Structure

 The Structure represents the backbone of the product and its most critical element because it bears all stress and the strain  generated by the bike during the ride. Up to now it has been very difficult to ream stresses in order to differentiate the tyre behaviour in different areas but Metzeler technicians, working over the years on the 0° steel belt winding process, have made another huge step forward. The new winding process allows to progressively ream stresses in the different areas of the tyre; as the result, every single steel string has been designed with a pre-defined resistance to stress for a specific performance requested. As a result, we now have a real interaction between carcass and belts thanks to the modular string winding tension from zenith to the shoulder: no compound at all would allow itself this level of result. The key of performance is the entire tyre design with no discontinuity in terms of performance due to wear or to different lean angles. The number of steel strings inside the tyre guarantees an homogeneous differentiation of performances, avoiding any “step effect” typical of multi compound technology. Lower tension creates more flexibility and therefore higher energy absorption, the compound increases the temperature and in a certain sense becomes softer.

Basically we are discussing high steel belt winding tension for maximum stability in the centre of the tyre and a progressive reduction of steel belt winding tension allowing maximum agility whilst tipping in and higher flexibility for maximum grip at full lean Another important aspect which contributes to making ROADTEC Z6 INTERACT

Profile

ROADTEC Z6 INTERACT benefits from the profile of the world famous Contour Modelling Technology (CMT) that has been world wide celebrated with the ROADTEC Z6. The immediately  perceptible result for the motorcyclist is neutral and smooth handling in all manoeuvres: in agile and fast changes of trajectory, the motorcycle always remains predictable, with never anything other than total reliability in the motorcycle-system and its interaction with the road’s surface.

Tread pattern

keeps the same tread pattern of the ROADTEC Z6 adopting the same philosophy of combining the drainage and mileage characteristics but with the basic concepts that sustain the sporting vocation of the sport tyre. Linear sea/land ratio distribution on contact patch at different lean angles features excellent water drainage for smooth and homogeneous riding

Linear sea/land ratio distribution on contact patch at different lean angles features excellent water drainage for smooth and homogeneous riding.In dry conditions, the performance equilibrium that inspires the ROADTEC Z6 INTERACT in all its aspects is manifested in perfect combination between sports grip and mileage, within the logic of the use of a Sport-Touring bike. The pre-defined stress distribution all along the profile helps to keep open all the grooves even under the high load which is typical of sport touring bikes; the perfect interaction between structure and tread pattern design ensures the perfect water drainage even in the hardest conditions.
