General

ECO Plus 2 - the new generation of the tried
and tested BPW ECO Unit
The BPW ECO Unit, proven a million times over in its
ECO Plus version, will be replaced from September 2007 by
the still further improved, new ECO Plus 2 design.
A rigorous upgrade of the components has resulted in a
signiﬁ cant weight reduction compared with the current
ECO Plus Unit.
In the case of the ECO Plus 2 the hub cap has a bayonet
ﬁ tting, enabling convenient ﬁ tting and removal of the cap.
Grease is supplied to the wheel bearings by means of a
grease cartridge located between the bearings.
The axle nut previously used is replaced by an axle bolt
with integrated torque limiter.
