Race bikers need a tyre that offers the highest level of safety – even if they ride with high speeds. Then a sport touring diagonal motorbike tyre is needed to offer them maximum adherence even on wet roads, and maintain the motorbike stable when turning. Despite this extreme exposure, bikers expect the tyres to have a long life. Well-known tyre producers like Michelin or Pirelli know the demands of their customers and offer appropiate sport touring diagonal motorbike tyres - diagonal tyres are still available, even if, radial tyres have a better speed performance and are preferred by most bikers.
Especially elderly bikers still use this type of tyres, while modern bikes are usually fitted with radial tyres. The steel wires of the casing's layers on diagonal tyres are crossed obliquely - for race motorbike tyres the angle is also narrower. The sport touring diagonal motorbike tyres have specific dimensions , e.g. 6.40-15. 6.40 is the tyre's width in inches, 15 is for the tyres's diameter in inches. On eiretyres.com you will find diagonal motorbike tyres in different dimensions.
