METZELER is proud to present its Roadstec Z8 motorcycle tyre:

• The profile design maximises flexibility, ensuring optimal ground contact in all conditions.
• The 3 tension zones use Interact technology for a longer lifespan and good grip on corners.
• A new high silica content compound with nano-particles to ensure performance and safety in any weather conditions.
• Rear tyre available in (M) and (O) with a dual rubber compound.
• The compound in the central part of the tread is approximately 45 mm wide (depending on tyre dimension) with a 70% silica content, specially designed to optimise mileage and ensure stability at high speeds.
• The tyre shoulder is approximately 88 mm wide on each side of the profile, with a 100% silica compound, which considerably increases grip on wet roads and prevents skidding in any conditions.
• The front tyre is also made of a 100% silica compound.

Handling, braking, comfort, etc. The tyres you choose affect numerous aspects of your machine's behaviour, whether on the road, the racetrack or off-roading. Therefore it is essential that you carefully choose the type that fits your needs best.
To help you, here are a few explanations that will help you decipher the information on motorcycle tyres:

• Dimensions: tyre width in millimetres and tyre height as a percentage of this width. E.g. 190/55, for a 190 mm width and 55% height
• Structure: radial (ZR or R) or diagonal (B), both tyres must be identical for this criteria
• Diameter: expressed in inches, e.g. 17 or 19
• Load index: the maximum load that the tyre can withstand
• Speed index: the maximum speed that the tyre can withstand
• M/C indicator: tyre use, M/C for motorcycles
• With or without inner tube TL (tubeless) for tyres without inner tubes, TT (tubetype) with innertube

In some cases, other information may appear, generally associated with the trade name of the tyre. Here is an example:

• A: Kawasaki
• C, F or GT: BMW specification
• E or B: Special carcass for heavy or loaded motorcycles
• G: Honda, Suzuki, Yamaha specification
• GTW: Heavy, fast and powerful Grand Touring motorcycles
• H: Honda specification
• K: Extremely fast motorcycles
• M: Suzuki tyres fitted on new bikes
• N: For Aprilia, Honda Ducati, Kawasaki, Suzuki, Yamaha, Triumph
• RF: Reinforced tyre
• WW: Tyre with white sidewalls

Other references of lesser importance are also found on the wall of motorcycle tyres (country of manufacture, DOT markings, etc.)
Remember to check your tyre pressure on a regular basis. It will ensure longer durability and increased performance!
