The best wet performance in the Sport Touring segment The wet weather handling of motorcycle tyres and especially the braking performance in wet conditions, is becoming an increasingly important feature demanded by the rider. This rider requirement occurs especially if it suddenly rains and a high level of security is needed. Metzeler has decided to develop the new (M) and (O) specifications to provide motorcyclists the latest technology in terms of wet grip by retaining a high level of performance in all other areas. The rear tyre of the specifications (M) and (O) has a bi-compound mixture. The rubber compound in the central section of the tread area, depending on the tyre size, is on average 45 mm wide, with a 70% silica content specifically designed for higher mileage and stability at high speeds. The tyre shoulders comprise of approximately 88 mm on each side of the profile and have a 100% silica compound, which increases dramatically the chemical grip in the wet and reduces sliding under all conditions. The front tyre also consists of a 100% silica compound.
