ODS Shock

[superhondaman]

Probably a silly question but can a front ODS be used on the rear?

Nope. Ya need the taper end to mate to the strut.

i have 2 struts,one with a flat end and one with a taperd end? i had a noleen fitted before it snapped, so it will fit the taperd one then?

Hmmm, not sure what you're asking here..........

But, there are fundamental differences between a front and rear ODS.

The rear has an internally threaded M6 hole into the piston shaft and uses a removable split collet (tapered cone) to locate the shaft into the strut with a recess in it (i.e. x56 onwards)

The strut without a recess is from an x55 type bike and is meant to be used with a silver friction damper of that era, but might be suitable for using with a more modern modified shock.

The front ODS is externally threaded to fit into the lower pivot piece.

The shafts are the same diameter, but cutting an internal thread into a front strut shaft would probable result in far too weak a structure to be stable, as there would be little metal left over between the internal and external thread.

Also, the top fixing hole diameter is much bigger on a rear than a front ODS.

Also another difference between the two is their Length and Stroke!

A front is 174mm, (eye to shaft end) and has a stroke of about 40mm
A Rear is 196mm (eye to shaft end) and has a stroke of about 50mm

Basically the gold body of a Rear ODS is longer.

Now, none of the above should put you off modding a front ODS to fit on the rear, as there have been some engineering marvels on this forum, but in my estimation, the problems out weigh the advantages....! <GRIN>

Think i will ditch that idea then! too much time on my hands thinking whilst the eye heals. Shall try the friction one but will get back to you soon about that ODS shock colin, if it does not feel very good.
