Im using 140/70R17 rear and 120/70ZR17 front battlax tyres. I believe there are a few variations you can choose for this setup but this combination is ok.

Dave Lum With any spoked wheels, particularly new ones, you need to check the spokes as they need time to bed in. You should be checking the spokes of your standard wheels regularly as well, or your mechanic should be. The wheels are ok, but like i said in the vid, the offsets can result in the front brake disc running real close to the cast portion of the lower fork and the rear sprocket is further out which means it will foul on the chain guide.

+Dargle Stickstopper Not sure.. i put these wheels on quite some time ago and they have not been off since. Your best bet is to contact them and discuss how they are supposed to be fit.. then explain why yours doesn't look right.

+OzDizzer - Torpedo 7 got back to me. I have to say their customer service was really good. The wheels were delivered in only about 3 days, and they were very quick to respond to my question on the bearing size. They confirmed that the 25mm (internal diameter) on the rear bearings is correct, and the spacers not only space, but also reduce the internal diameter down to 20mm to suit the axle. I was initially concerned about this, but some googling suggests it's not unusual. Still need to pick up some bits and pieces, like disc rotor and sprocket, SM speedo drive (maybe), but then I'll go ahead and try to fit them!

What profile rear tyre are you running and does the tyre hit the chain only when riding?

@@OzDizzer 150 sport demon. Hits when riding. I've done a few hundred k's (hills and hwy) and it's barely eating away at the side. I think a brand new chain should totally fix it as this chain is at least 10,000ks old. currently only 5mm between chain and tyre's edge and is properly tensioned.

The speedo eliminator (B&B) is exactly the same width as the factory speedo. From what i can remember the B&B requires no spacer run inside it. Ie. you eliminate the need for a spacer or the factory speedo pickup. Ideally brake disc would be centered in the brake caliper, much like the factory one. I *believe* spacers should be setup such that the overall width of the wheel and spacers between the forks is exactly the same as factory whilst ensuring the brake disc remains centered in the caliper. At this point your probably thinking, well doesn't that mean the wheel is no longer centered in the forks... and you would be right.. however... i also *believe* this is common and not really an issue. If you think about the back tire, if its wider than the factory one, then this will almost definitely result in the rear hub needing to be wider to space the sprocket out so the chain doesn't rub on the tire. This will move the center line of the tire to the right, away from the chain. You could play with spacers here to try to center the tire more, and push the sprocket closer to the swing arm, but this would also require that you somehow space the engine sprocket further out from the engine. A related point of interest is that i dont think the centerline of the front tire on the bike will line up with the rear tire centerline.. and again i *believe* this is normal. If i was to do it again.. i would probably do as i said above.. center the disc in the caliper with custom spacers.. this would mean you can run proper tapered sprocket bolts (not the rubbish you see in my vid.. found out they are are poor choice) whilst still clearing the cast portion on the bottom of the fork. Failing that, i might consider sticking the hubs in a lathe and shaving 1mm off the face of it to inset the disc a bit more. On a related note, i strongly recommend having the spokes on those rims re-torqued..

So it won't be too much of an issue if it's not quite centred? I managed to move it over jus a touch more with a 2mm washer but haven't had time to tighten up and spin the wheel to see how the brake rotor feels in the pads. Is your front wheel central or off by a few mm? Thank you for the quick response and priceless info. It's good to ask someone directly who has done the same conversion. Not a lot of people have theses wheel sets.

I'm also using stock rotors with different bolts the original bolt stripped on the dirt rim so I drilled them out. The new ones are even more flush and high tensile.

+gargantuandick , with a name like that you don't need brakes, just unzip and use it as a land anchor.. hahaha. In regards to the rims, wheels, i took them off to put offroad set back on for a while. Thoughts at this stage are: * You should get a bigger brake disc. * The offset spacers or the machining of the hubs doesnt seem quite right: ** The alignment of the rear sprocket with the engine sprocket is a bit off. Not sure if they have fixed this in with that they currently sell, but its something i think i would prefer to resolve if i was to put them back on. ** The alignment of the front brake disc in the caliper is off by a couple of mm. Which although it doesnt sound like much, given the tolerances of everything between the forks it makes a noteable difference.

Imran Bahar I bought mine from amazon.com many moons ago, possibly before EBC changed products codes and caused a lot of problems. You could try thumpertalk.com/shop as they still sell kits. You may need to cut down the supplied bolts to ensure when you tighten them up the bolt doesn’t protrude through the back of the bracket and hit the caliper.

@@OzDizzer thanks alot for the reply Appriciate Do you have the parts number? Or how can i search thet spare parts what i have to type when im searching?

@@mib668 Try the following link, they have the brackets by themselves or as part of a kit. NOTE: Don't blindly order, check with them prior to ensure it is what you actually need and that it will fit. It does look like they have reviewed their part numbers: ebcbrakesdirect.com/motorcycle/suzuki/dr-z-400-sy-ey-y-sek1-ek1-k1-sk2-ek2-k2-k3-sk3-ek3-k4-sk4-ek4-sk5-ek5-k5-ek5-ek6-sk6-k6-sk7-ek7-k7-sk8/2000-2008/37790

+Scott teh caliper relocator bracket and 320mm shoudl do the trick. Make sure you're buying the right relocator

+EthanKRETA that's the problem. i can't find the "right one"

+Scott teh I bought mine in 2013 from: www.amazon.com/gp/product/B00666L14G?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 However, someone put a comment on there that they were sent the wrong bracket which caused problems. I didn't have bracket problems, but i did have issues with the supplied bolts being too long. Will try to figure out the the bracket type is over the weekend and post.

I can solve bolt length problem. But confirmation on bracket would be great. Thanks

My bracket has SM-015 written on it. It looks very much like this one: www.motostrano.com/EBC-DRZ-400-Brake-Caliper-Relocator-close-out-p/015.htm That being said, motostrano looks like a massive rip off. Looking at the EBC website, it looks like they provide a relocator with the disc. I guess you need to specify which one you need when you order the disc. ebcbrakes.com/product/supermotard-contour-rotor-kit/

Yes, and yes i sold it. Can't figure out how to send you a PM through youtube?

@@dylanhillier8107Ah nice! Did you only sell it recently or has it gone through a few owners? Do you happen to remember the odometer reading before the TrailTech unit was fitted? Any info about the bike is appreciated - I live in Adelaide and am having it shipped over. Cheers!

If it is the same bike, and it hadn't gone through someone else first, then you should have also received all original parts, spares, etc, along with the bike. This box of stuff would contain the answers you seek. Also, if you bought the bike you would notice it had the same tires as in this video which gives a pretty good indication of, sadly, how little it had been ridden over the past few years.

Yeah not too bad to swap back once you have done it a few times. Biggest pain is probably the chain if your don't use a master link which can be easily removed. Probably < 30 minutes. Ideally, if you go from stocker rims to motards you should also adjust the headlight. Swapping the kickstand is pretty straight forward as well.

Yeah, it would be awesome if Torpedo 7 would fix their kit and send me one that has better spacers ;)

+ElectricRides agreed... i will take donations ;)

Tank To Chest I’d agree if the intention was for it to spend most of its life on tarmac.

Probably, but back when I bought mine there weren't many options that didn't exceed the cost of the bike and other ones were hard to come by. Great to hear they are easier to get now and fit right the first time. 👌
