RENTHAL TWIN WALL 999 HANDLEBARS
The revolutionary Twinwall design features a patented dual tube construction that is based off
of the same principles seen in the aircraft industry, resulting in the worlds strongest Motocross handlebar.
The outer tube is made from 7010 T73 anodized aluminum, offering extreme resistance
to mechanical damage and corrosion. The inner tube is built from ultra high strength 7010 T6 aluminum,
and is hard anodized to resist throttle tube wear and increase fatigue life.
The bonded, lightweight, single bolt clamping system used on the cross-brace increases bar strength,
while allowing some bar flex for improved shock absorption.
Borrowing principles from aircraft design to give the best combination of lightness, strength and safety,
the Twinwall handlebars are by far the most advanced set of bars available for your machine today.
Since their introduction in 1998, the Twinwall® have been the handlebar of choice
for more professional race teams and has helped more riders win championships than
any other handlebar in the world. Join the Renthal family, and get yourself a set of Twinwall’s today!
