DRZ400sm Factory Rear Wheel/Dish Offset

Recommended Posts

Hello all,

I apologize if this question has been asked already, I have spent the last 30 minutes trying to find an answer to my question to no avail. So here we go:

I decided to get my factory wheels powder coated (just the hubs, spokes, and nipples) to help jazz things up a bit. I sent the wheels out to my powder coat guy, he is a huge Suzuki guy and is a factory certified Suzuki technician as well as an MMI graduate with perfect attendance. The guy really knows his stuff. However he is more of a GSXR specialist and doesn't mess with dirt bikes too much. So after coating the wheels he sent them to the local Suzuki dealership to have them re-assembled and trued. I'm not sure how much these guys know about DRZ's as they are more of a Yamaha/Kawasaki heavy dealership but they do sell a few Suzuki's (This is the same place I bought my sm brand new) and the guy who laced the wheels is a big name in the local motocross scene. Anyways; my guy got them back, called me, and I picked them up and installed them on my bike immediately. After putting the bike back together I immediately noticed my chain was now rubbing my tire.

I did some research and came to the conclusion (educated guess is probably more accurate) that the wheel offset is incorrect. I'm not really the most comfortable attempting to fix this myself but I figure it has to go back regardless if I don't, so I might as well try and take a stab at it. I contacted my guy and he said he verified that the wheel is true and that the hub was perfectly center when he received it back from the dealership. However, I have read on Supermotojunkie that the DRZ has a right side offset from the factory and am wondering it that's what the issue is. If that is true, does anyone know what the offset is supposed to be? Or how I can determine what it should be? Also will I be able to get away with just using a spoke wrench to try and tackle this by myself? The bike has stunt pegs so I was just gonna disconnect the chain and set it up on jack stands to use the swing arm and axle as a "truing stand". 

Also, any other things to look for that might suggest it's not an offset issue? I added a new chain and sprocket as well but the chain is a 520 chain just like the stock one and the sprocket is a steel sprocket as before as well, so I doubt it's any different in thickness. It came from Supersprox and is nice and beefy.

Thank you all in advance for your help! Any information is appreciated.

lol .. your 'expert' guy should have known the hub in fact does not get centered .. if i recall correctly, the easiest way to see if its right is the brake disk should be even with the right side of the rim ..

Don't know what factory offset is.I do know when I did the super motor wheels for my E conversion I needed to go basically as far as I could.

The spokes will contact the caliper if offset too much.

Your best bet may be just moving it over until you have enough clearance between tire and chain.

If you change offset, its a good idea to remove tire and make sure the spokes aren't protruding thru the rim, which could result a flat tire

As above.  Loosen spokes on 1 side and tighten on the other until you have chain clearance.  Then spin and adjust and true, it's not that hard.  And if you really get it messed up just start over.  In an evening you will be an expert.

What I don't know is if the spokes are all the same.  There could be 2 lengths or even 4 different lengths.  If the spokes are different and not in the right places then it is full disassembly to sort out the spokes.  But still not that hard.

Does anyone actually have the factory spec? I'm about to lace up my wheels and it would be nice to have the correct value dialed in from the beginning.

Welp, I got the tire offset properly and trued up. Like Noble said, finick around with the damn spokes for a few hours and you become an expert! haha.

That's the good news. 

The bad news is that a handful of the nipples got pretty mashed from the spoke wrench. I wasn't expecting them to be quite so soft. So unfortunately I'll have to buy more and have them coated and replaced.

Gary, what cowpie said was dead on correct. Line up the right side of the rim evenly with the brake rotor and you'll be right where you need to be.

I gave some thought to this. The 2.15  x 18 "dirt" rim doesn't require offset, but a 5.0 x 17 SM rim requires the offset to keep a 160 section tire off the chain. I'm using a 3.50 x 18 rim running a 130 section tire (street tracker setup), so I shouldn't have any interference issues as my tire is over 1/2" (15mm) further from the chain.

You will more than likely be fine. For the record though, the SM rim is 4.5" x 17". You will not have any chain interference issues, but your bike may track funny.
