RU EXUP Front Spindle

Is there a difference between the RU front fork spindle and the one from the foxeye as IIRC the Foxeye has Ohlins forks?

Please someone set me straight on this.

1990 model front spindle = 3GM25181-00-00

91-93 = 1HX25381-01-00

94-95 = 3GM25181-A0-00

....what are differences and have I got info right?

Cheers.

89&90are def different as they have conventional rwu forks and from info posted by others on the site I believe the diameters are different for the 93 when compared to the later fox eye as the bearings are dire rent so wheels aren't a straight swap

Hope that helps

Has anybody got dimensions of 92 vs foxeye, I wonder?

Check the main site 'technical' data section where you can see both spindles for earlier RU and Foxeye. That way you'll be able to tell what you've got.
The Foxeye spindle IS deffo different to the earlier RU in that the Foxeye spindle appears to be the same design as the Thunderace / YZF750 (unsure if they're interchangeable though) while the earlier RU spindle looks similar to the right way up 89/90 models.
The Foxeye has a hollow castellated end and threaded other end, while the earlier RU has a proper nut job and threaded end if that makes sense?

i think both spindles are both 25mm od but are different fittings as already stated,
the front wheel in the foxeye is the same as yzf750 if that helps any

what are you trying to do?

Although I've had no problems with front end over last 5 years, The spindle looks slightly oversize to me....I'm lost.

I assumed it might have been replaced by a later foxeye or yzf one.

The spindle appears to be a hybrid of the two listed in that the bolt head is same as 91RU and the shaft of the spindle is thicker than the rest where it seats in fork leg bottom.

Yep the RU spindle is different from spindle in the 89/90 std forks.
