CR80/85.150R forks with CRF250 front wheel??

Recommended Posts

I'm wondering if anyone has put a CRF250R or X front wheel on the CR80/85.150R forks? I'm looking at this right now and I'm not sure you can get that CRF250 hub centered and have the disc rotor line up with the caliper...Of course you need custom spacers and collars... but I'm curious if anyone has done this as I'm conserned it won't fit.

I don't know about crf250 /450 front wheel fitting,but you can adjust spokes, and move wheel to one side over 1/2 in no problem. I would never go this route as Crf 230/ xr250/ xr400/ 600 so easy to install.

The 250/450R front wheel has almost identical dimensions to the 230F front wheel so if you could get the bearings figured out or spacers then the 250R wheel should be no problem.

Are some of you using the XR250 front wheel? I m building this from scratch.. I  Don't have a CRF230 front wheel handing around.

I have used all wheels In my post above all xr400 wheels. xr250r  86/04    xr600 the later wheels    The most easy xr250r same bearings.  Xr4 and 600 has 17mm axel so need change parts.  For rear if you want a drum the early Xr250r 86 up,but you need use 230 backing plate. Or my disk brake rear is from late Xr250r.

This is totally &%$#@!ing confusing. See below... If you want a 15mm ID on the axle for the front I looks like the 230 and XR250R 's work.... but all years for the 250R? And what about the rear?17mm rear stock 230 axle..... 

 

6002 … 15 x 32 x 9 …. CRF150R/RB Front
6202 … 15 x 35 x 11

 

 … Front;  CRF150/230, all XR250, all XR200R, KDX200
6302      15 x 42 x 13 … XL185S rear
6003 … 17 x 35 x 10 … 89-91 RM125 front, 86 89 CR125, XR400
16003… 17 x 35 x 8 
6203 … 17 x 40 x 12 …. XR200R rear, 90-03 XR250 l side, 81-83 XR200R rt, XR400.
6303 … 17 x 47 x 14 …. 90-03 XR250 rear sprkt side, CRF230F rear, 81-83 XR200R lf

My 2006 CRF250R front wheel uses 6904 bearings, 20 x 37 x 9.  There ain't enough meat on the CR80/85 CRF150R forks to drill/bore a 20mm hole on one side and 25mm hole on the other to use a CRF250R axle.  You could either:

-  Sleeve the bearings in the 250R wheel so you can run a 35mm OD bearing.  Chuck suggested this and has done this before IIRC.

or

-  Make spacers which are 20mm OD and either 12mm or 15mm ID to slip over your chosen axle and into the 20 x 37 x 9 250R bearings.

If you want to use the mini bike brake (easy), the easiest is a CR80/86/150R hub and rim of your choice.
If you make or buy a caliper bracket for a twin piston caliper and big bike rotor; then the CRF230F or XR wheel is an easy bolt on.

That is the only sane way to do it Xr250r wheel  no need to have custom machine shop work unless its your shop.  Sometimes used parts free are not free after mods to fit.

I went this route on my latest group of mods to my CRF230. I have the 150R front end, 150R talon hub mated to an Excel  21" Takasago rim. I'm using the CRF230 front caliper mounted on an applied racing bracket. Rotor is a Braking wave rotor at the stock 150R 220mm size. It has the same braking approximately as the stock CRF230

Mine is similar with a CR80/85 hub and rotor with a XR250R caliper and MC. Plenty of braking power with the 21" wheel. I started with a CR80/85 caliper and a XR250R MC but not enough braking power. So pad area, piston area, and pad material makes a difference

I caved in and purchased a CRF230 hub. Brand new... will build up a wheel from there.
