Hi my nsr recently failed its MOT, mainly due to the rear shock needing to be replaced. it's from 1997 and after looking round a bit on the internet i found this and wondered if it would fit my bike?

That states it is for a 92/93 FN. So I presume that means the unfaired model. I owned a FL which was made in 1990 and know first hand that the shocks are not a simple swap, the eyelet on the top was different and the suspension linkages are not the same.

However by 1992/1993 this may have changed as the FL seemed to have quite a few unique parts. You need to get the dimensions of the shock that is advertised.

It is always worth giving david silver spares a call if you need honda parts.

knowing that english people (sorry) are not very often precise on the year of their bikes , look serial number . if it begins by HI-xxxx year is 1989-1992 and by ZDCJC22 it's 1993-2001 (foxeye)
faired or unfaired doesnt change anything but the 2 models cannot be exchange
here is a pict of a foxeye , you can see the adjustable spring compression

it's a 1997 foxeye model. on the website it says the part is for 92-93, does this mean it won't fit then?

to be sure only the length (between the fixing axis) which the point , because JC20 use 17" wheels and JC22 use 18"

OP, just had a look on the Hagon website and according to them, all JC22, ('94 - 2003) shocks are interchangeable.

With a little knowledge and some small modifications, you can use shocks from other bikes. I've had to do this myself when a replacement shock has been impossible/too expensive to find or the original one is pants. I've also found a more modern shock can work better on older bikes.
The most important things to look at are the distance between the two mounting points and the type of fitting. the linkage can be narrowed if the "fork" fitting on the bottom is too narrow and the top lug can also be modified to fit. You're also looking for a donor shock that sits at a similar angle to the one you're trying to replace and from a similar weighted bike.

If you're still looking for a used one, as I originaly said, if it's off an NSR125, and looks like yours, ie; has the two castelated adjuster rings on top of the spring, it should fit.

This is my old 350YPVS with modified RGV250 linkages and an Aprilia RS250 shock.
