What forks are you trying to put into what bike?


Im assuming your using the yokes and stem that match the forks.

hi yes the cup has to be 48mm wide and the stem that goes init is 23mm according to my vernier,i have seen some tapered roller bearings that have a cup cone 48mm and the bearing is 25mm nearly right but i need 23mm bearing and cone to match do you know anyone that sells a range of them cheers.

Im in the middle of a bearing conundrum very similar myself, Ive discovered that for a 48mm OD the standard ID is 25mm, and anything other than that is rare and expensive.

If they're the same size where they fit in the bottom yoke, you can sometimes get away with swapping the stems over. You'll need to get it profesionaly done though.

[Robby]

If you're fitting the yokes from a different model onto your bike, one way to make it all go together easily is to swap the stem. You should be able to get it pressed out of one set of yokes and pressed into another.

I knew a guy that was doing this to a Triumph Daytona front end onto a Suzuki VX800, to take advantage of a 17" front wheel and twin discs.

[Vincent]

Have you checked the steering stops on the bottom yoke are in the right place too? Although with narrower forks you might be ok.

thanks for help, i think im going to have to go with the 25mm 1,s and just make a kind of sleeve over stem so bearing can then sit on that should work ,i hope lol ,is that a good idea or dodgy idea?????????????
