    If you research the Metzeler 777....

    Per the manufacturer ... it is a DUAL compound tire, with HIGH SILICA compound on the sides!

    If you ever research multi compound tires, the SOFTER SILICA rubber placed on the side tread is for traction and the best rubber to grip the road. The NEGATIVE is that it wears faster then the CENTER harder compound rubber of the tire. Sport Bike tires are very sticky because of the HIGH SILICA content, yet don't last.

    The Honda RUNE 2003-2004 Dunlops were a DUAL Compound tire and Dunlop discovered after 2 years that the FAT 910lb. Honda Runes were eating the softer SILICA based compound on the sides of the front tire prematurely. The Rear Tire was a single compound and wore evenly. They wanted the best traction but discovered that aggressive riders were LUCKY to get 3000 miles on these dual compound Silica front tires, riders not so aggressive were getting 4000 to 6000 miles on the front tires MAX ! Yet all of us were getting 8,000 to 12,000 miles on the same Dunlop rear tire.

    From an Engineering report ......
    To understand the miraculous effects of the silica-silane mixture, one must understand that since the development of pneumatic tires, engineers have lived by a simple and immutable law – soft tire compounds get more grip, but wear faster and have high rolling resistance, while harder compounds wear slower and have lower rolling resistance, but get less grip. The inevitable tradeoffs that engineers must make between grip, rolling resistance and treadwear is known as the “magic triangle.” To properly balance these properties for a specific tire has been the goal of every tire engineer who has ever mixed a compound.

    This Metzeler front tire has a SOFT rubber Silica compound on the side and is not designed to last on a F6B. Left turns will eat up these softer tires.
    Look at the METZELER photos attached where it explains the purpose of this DUAL compound, Metzeler shows you that the HIGH mileage rubber is on the center. Most riders buy for PRICE and not for what the tire is designed for. This tire does not belong on a F6B if mileage is what you are after.
