We take them for granted, but th­ese do-any­thing tyres are hardly run-of-the-mill

Motorcycle News (UK) - - Garage -

Sports tour­ing tyres have an in­cred­i­bly tough job. They have to suit all types of ma­chine, from 200bhp su­per­bikes to light­weight com­muters and heavy­weight tour­ers, give con­fi­dence in tem­per­a­tures as low as 5°C, cut through the heav­i­est rain, give ex­cel­lent grip on dry roads, and pro­vide a sporty steer­ing char­ac­ter­is­tic while re­main­ing sta­ble. On top of all that, they’ve got to give thou­sands of miles of life, too.

Logic sug­gests that cre­at­ing a prod­uct to achieve all this would be im­pos­si­ble, as the soft com­pounds needed to gen­er­ate feel and con­fi­dence in cold, wet con­di­tions are the very same com­pounds that can be eas­ily over­heated in warm, dry, high-mileage sit­u­a­tions.

But in re­cent years all the lead­ing man­u­fac­tur­ers have now cre­ated prod­ucts to give Bri­tish rid­ers the ideal so­lu­tion for all types of road rid­ing, which is why sports tour­ing tyres rep­re­sent the ma­jor­ity of all mo­tor­cy­cle rub­ber sold in the UK.

Met­zeler cur­rently lead this seg­ment, the Road­tec 01 tak­ing top hon­ours in MCN’S sports tour­ing tyre test last year. Tech­ni­cal boss Sal­va­tore Pen­nisi gives us an in­sight into achiev­ing the im­pos­si­ble.

Who knew there was so much sci­ence in rub­ber? ? 4 2 1 3
