Vintage Dirt Bike Q & A

Looking for help on both rear wheel and front wheel, MR250.
In the rear,,, is there some type of a cap/spacer on the left rear axle of the bike? mine does not look complete in some way. Maybe there is a manual or picture to show me what is suppose to be there...
On the front wheel,, speedometer drive,, what the heck is in there exactly that makes the speedometer drive turn from the wheel itself? Im fairly certain my speedometer cable and adapter are fine there.... they spin by hand and all works. But on the wheel,,,,,,, uncertain.... thanks folks...

You can go to Honda parts and look at the exploded diagram to see what all your missing.

It looks like the MR250 rear wheel uses the same setup as my Hondas - one LH sliding collar on the swingarm (the RH one is built into the axle end), and left / right axle spacers.

If I recall, my MR250 front wheel had the speedo drive fitting into a recessed ring that was screwed into the spoke retainer, which then screwed to the hub. I don't see any spacers in the parts diagram. I believe the speedo drive had a retaining screw to the RH fork leg, but I didn't have the forks, only the wheel.

Yes for the front speedo drive all the parts are not listed on any website. The speedometer drive interfaces to the hub. between those two I am missing something. Just not sure what it is.


I will investigate further on the back . maybe i have all that is required, it just looks odd.

You couldn't determine what was missing from the two diagrams I linked to in my reply? Every part is there.
