Det verkar som att metzeler har lyckats att förbättra M7RR ganska väsentligt till nya M9RR om man skall tro detta.
Metzeler Sportec M9RR, has some big shoes to fill and the claims of its enhancement are bold; better all-around the spider chart in terms of mileage, dry grip, lap time, consistency, handling and wet weather performance. Off we went to the roads around Ronda in Southern Spain plus the private Ascari test track to assess the declarations of this latest road and track-biased rubber.
New compounds and layout of those compounds plus a whole new carcass construction had led to a 5% increase in effectiveness of the contact patch while at lean and a 3.4s improvement in lap time at the 5km Pergusa test circuit on the same day, in the same conditions, with the same rider, on the same BMW S 1000 RR using the M7RR followed by the M9RR.
