nice conversion! no, the 1983 to 1988 rm250 forks werent upside down. these slot straight into the DR triple clamps, and the DR front wheel, axle, speedo drive and spacers work perfectly. BUT you need to make a caliper adapter plate to suit the DR front disc. same conversion works on the older RM125 and RMX250 forks (e.g. 43mm fork stancheons like the DR650). before they went upside down.

edit: correction, the rmx250 fork stancheons are 45mm so you will need the triple clamps as well. but front axle and spacers etc identical to the RM so the DR650 wheel will slot in easily, just make a caliper adapter plate to suit. rmx forks have the added advantage of adjustable rebound damping.

Nicely done ADV8. That certainly solves the rotor issue.

I finished my conversion to white today...

I installed a set of RM250/125 forks on my Dr650. I'm running a 120 front tire, I've got minor tire rub on the left fork when braking heavy. Are the wheel spacers the same??

Does anyone have any pics of a Vapor speedo pickup mounted to a 320mm front rotor. I'm thinking it's gonna have to be mounted off the back wheel.


Thanks

Wow! That is sharp!

I miss my DR. I was thinking about tardin' it but I didn't. I'm thinking about buying it back from the current owner. Even with it's weakness, it was still the most enjoyable bike I've owned. I just got bored with it in dirt trim. I bet the sumo conversion is a blast.

you didn't mention year model of your forks. far as i can make out, the 1983 to 1988 rm250 and rm125 forks are all the same (slightly softer springs in the 125). 43mm stancheons slot straight into the DR650 triple clamps. axle, and wheel spacer on the non-speedo drive side are identical. even the brake line mount gets screwed on at the same spot on the fork.

i didn't get an RM front wheel with mine, but assume they have a spacer in place of the speedo drive. tyre goes nowhere near the fork leg on mine under braking.

if anyone is thinking of doing this, i used 10w fork oil, put the damping on the maximum setting, and preloaded the springs by an inch. seems to work a treat for my 95kg, havent hit any big jumps yet but doesnt feel anywhere near bottoming out on smaller jumps and hitting woops fairly hard. forks were only $150 on ebay, $20 for heavier fork oil, so very happy with the result.

dodgy brothers way is just superglue a magnet to the front disc. done it before when the vapor setup wouldnt work, got the "rare earth magnets" on ebay for a few bucks.

You need to check the tyre/tire is centred in the forks.

When I mentioned RM250 forks some time back I meant the USD fork RM250's,that's all.
Are they the same as the Showa RMZ fork or a Kayaba USD.

Then there is Race Tech valving.
very late reply, but a bit of useful info if anyone else is thinking of this. if you can get the RM front wheel included, from what i've seen all the RM models share the same front disc bolt hole pattern as the DRZ400 and DRZ400SM (check specs for any particular year on metalgear.com.au). you can get a drz400sm 310mm disc new on ebay posted for around $130. then buy the 310mm caliper adapter plate for $30 from here and just machine the spacers specified. a 310mm rotor makes it a lot easier to change wheels over, there's very little room to squeeze the caliper on with the 320mm disc.

I'll try and get some pictures posted of my bike. I just got it wrapped up yesterday.

How can the tire be moved to the right?? (if it's not centered)

machine new wheel spacers to get it centred. easy way to do this is buy a pile of big washers that will fit on your front axle, try to get different widths (e.g. 2 and 3mm widths) so you can use combinations to make up any size.

when you've got the right number on each side to get the front wheel centred, tighten up the axle to make sure it all works nicely. you'll now find your disc is out of alignment probably, so loosen the caliper bolts off so you can get the wheel properly centred. next you'll need a bunch of washers to work out what caliper spacers you'll need to get the disc aligned correctly. tighten the caliper bolts to make sure the disc is centred in the caliper.

when it all works, just get the wheel and caliper spacers machined to suit from alloy round bar.

Thanks
For the Warp 9 320 rotor I just used some JB Weld to place the magnet on the rotor, but for the EBC 320 on my stock hubs, I had to use one of the replacement rotor bolts with built in magnet. Even then I had to remove a slight bit of the lower inside of the left fork slider to clear the bolt. The EBC rotor on the stock hub is a very tight fit. For both I used two large nylon ties to attach the sensor.

Do you know if anyone of these with fit the EBC rotor??

To cush or not to cush...

Ok all, looking to add some moto rims to the bike. Seen a lot about cush drive, but no definitive good or bad to not having it. For those who have cushless or have ridden cushless, what say ye?
