Pirelli is proud to present its Scorpion MX Extra X motocross tyre: Front tread blocks: shaped like arrow heads for greater directional precision and good visibility in a straight line. The blocks' V shape improves stability when braking and control at an angle. Rear tread blocks: maximum traction on all surfaces. The casing and black carbon compound strike a perfect balance between rigidity, reliability and long lasting performances. Good grip and traction across a range of surfaces (from mid soft to mid hard). Ideal for training; the perfect compromise between performance and durable resistance. The same tread pattern but with improved rear tyre rigidity thanks to added reinforcements ("bridges") and with a new front tyre based on the Scorpion MX Soft 410. Carcass features various thicknesses with high puncture resistance and maximum flexibility to absorb shocks from jumps and obstacles. Ideal for training on any surface, offering uniform block wear, good deformation resistance and a longer tyre lifespan. All NHS (Not for Highway Service) motorcycle tyres are for competition use only and cannot be used on public roads. There is therefore no official homologation.
Grip, 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: width of the tyre in millimetres and height of the tyre as a percentage of that 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 as far as this criteria is concerned
• Diameter: expressed in inches, eg. 17 or 19
• Load index: the maximum load that the tyre can bear
• Speed index: the maximum speed that the tyre can bear
• M/C indicator: use of the tyre, M/C for motorcycles
• With our without an inner tube: TL (tubeless) for tyres without an inner tube, TT (tubetype) with an inner tube

In some specific cases, other information may be included that is generally related to the make of the tyre. Here are some:

• 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 less important references also appear on the tyre sidewall (country in which it was made, DOT marking, etc.)
Remember to check your tyre pressure on a regular basis. It will ensure longer durability and increased performance!
