Description

Feel the RRace, Feel the RRoad.
RACETEC™RR, born to win in public road races, delivers the best performance!.

■Front Grip
Grip performance in all road conditions
The course of a public road race has a variety of road conditions.
RACETEC™ RRCompound was developed for every situation.
RACETEC™ RR uses selected polymers and resins blended with various grades of carbon black to enhance responsiveness on slippery surfaces..
RACETEC™ RRFront tires engage with road surface particulates, increasing grip and wear resistance. Furthermore, it has a long service life even on harsh road surfaces..
Polymer blend provides high flexibility even at low temperatures..
RACETEC™RR is adaptable to a wide variety of surfaces and temperatures, so the front tire compound can be selected according to the rider's preference:K2VERSION for high stability and precision when entering the corner, or K1VERSION for predictability and good grip feel. VERSION for predictability and grippy feel, depending on the rider's preference..

■Rear Grip
Grip performance in all road conditions
The course of a public road race has a variety of road conditions. RACETEC™ RRCompound was developed for every situation.
RACETEC™ RR uses selected polymers and resins blended with various grades of carbon black to enhance responsiveness on slippery surfaces..
For rear tires, select tires based on the Asphalt coefficient of friction (high hardness/friction and low hardness/friction, depending on circuit or road race) and road surface temperature (threshold is about 25-Degrees-30C)..
RACETEC™RRRear tires have two blended cap base structures and a SUPER conductive CenterStripe that distributes heat to the tire shoulder to maintain tire temperature even at long straights and ensure optimal grip at the corner ring. This ensures optimum grip at the corner ring..

■Stability
Accuracy and stability at high speeds
RACETEC&trade's RR features a composite structure divided between Crown and Carcass sides for optimum adaptation to any situation..
Stability is important when running at full speed on long straights (aerodynamic interference) on public roads or when passing under sewer covers, road surface repair marks, or bumps..
In both cases, the motorcycle is suddenly lifted and then lands on the ground, causing both tires and shock absorbers to compress, resulting in a temporary loss of stability at the subsequent rebound..
Crown section is made of special Rayon fiber. This fiber has high linear density and stiffness, and the entire fiber can sustain high stresses and loads and maintain the tire shape..
In addition, the fibers also serve to mitigate rebound strokes, distributing and absorbing shocks throughout the carcass and dampening the rebound as it returns to its original shape..
The SIDE section has a robust structure with a low deformation rate and maintains the entire structure even under pressure, enabling accurate tracing of the targeted line even with long straights and full banks..

■Lifetime
Long life and consistent high performance
Distance driven on public road races can be as long as 240 km.
This is equivalent to about 3 times more than Circuit runs!.
Therefore, durability, stability, and sustained high performance are the keys to victory..
All RACETEC™RR products, TireCompound, have excellent wear resistance due to the homogeneous dispersion of the components in PolymerMatrix achieved by Metzler's proprietary mixing technology..
Tread groove layout minimizes tire wear and blocks Schallamach waves that deform the compound..
RACETEC™ Schallamach wave breaking angles of Tread groove in RR are the result of analysis of data obtained from Race on public roads.

■Tread groove Layout
Minimizes wear.
Fragmentation of abrasion wave.
Slick areas and ground surfaces are the largest.

Caution

*Please use the tire corresponding model on the publication as a reference. There are cases that it may differ from the actual mounting size. There are cases that it may vary in size depending on minor change and model, special specification vehicle and custom situation, even if the model name, displacement and year are the same. Please be sure to check the tube, size, speed symbol, load index, tire type of the tire that is actually mounted, and select size and pattern at your own risk.
*Please check with the arrow of the tread shoulder part, side wall part for the presence or absence of rotation direction.
*Please note that the product specification may change due to manufacturer reasons.
