Drz400E to SM swap gearing

Recommended Posts

Hey guys looking for opinion on gearing for my E model that I'm planning on making my do everything bike so during the week use it as SM and be a hooligan and then on the weekend go trail riding. So my plan is to leave the dirt wheels at my cousins house (ruffly 1 hour highway ride from my house) where I ride trails. I plan on riding there in SM form and switch to the dirt wheels there and then switch back for the ride home. My current gearing is 15t front 47t rear with the E chain which I'm pretty sure is 112 link (don't quote me). I would like to be able to stick with the 15t front and chain and just swap the wheels I would like to leave the 47t on the dirt wheel. My question is what size rear sprocket for the SM wheel and chain length would you guys recommend for my needs.

With 112 link you would best to go with 44T on the SM wheels. Not sure if you could go 43 or 42 but 41 tooth wont fit with 112 link chain.

15/44 is a good compromise for the street. 15/47 it good for trails.

You can go down to a 44t rear on the SM wheels, but any shorter and the chain will need to be cut down. If you could run 15/47 on the E wheels and still manage a 110 link chain 15/41 or lower it would be great for SM duty also.

You cant do 15/47 on 110 link. you can barely fit 15/44 on 110 link.

I run 110Link on my L7 E so I could run 15/41 SM wheels and 14/44 dirt wheels.

Exactly, It is going to be a compromise running 15/47 and a 112 link chain. It is going to suffer on the road with SM wheels.

I guess it all depends on weather you do more road or trail.

If you do more road go to 110 link and and change between 15/44 and 15/41

If you do more trails stay with 112 link and change between 15/44 and 15/47.

Hows 15/44 on the trails

You don't have to run a 44-tooth sprocket. You can certainly fit a 43 and possibly even a 42 using the 112-link chain. 

have you run a 15/42 set up with the 112 links

Nope. I did try 15/41 once and it didn't work, but it was close enough that I would try 15/42 if I wanted taller gearing.

15/44 on trails, gravel light dirt is fine. It when you need additional torque going up more technical elevated terrain that you need to feather the clutch more. 14/44 is better but a PITA to change the front sprocket if changing wheels every weekend. 

I only have 47, 44 & 41 tooth sprockets so can only tell you that 44T fits and 41T does not fit 112 link chain. Others might chime in here if they have.

I've been on trails I shouldn't have before with 15/44 and it did ok. I wouldn't recommend it for any serious offroading though. Where you at in Michigan?

      Hey all, 
      I'm looking at buying a 2004 Suzuki DRZ400EK or at least I think it's an EK according to Vin lookup websites, but it does not appear to have a kickstarter. I was told the bike was owned by a motorcycle dealer and that it has a current green sticker, and a California license plate but has not been registered for the streets since 2011. I want this as a dual sport but am not clear if the fact that it already has a plate means I am good to register it or if maybe they took away the ability to register it after it was plated, California loves to do that kind of stuff. Since the bike was owned by a dealer I would think they were up on the latest regulations in California, but who knows. Can anyone add any insight as to what I should look for on the bike itself like the carburetor, model numbers etc? Or do I just try my luck at the DMV?

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey Guys,
      I recently bought a 2003 DRZ400S and thought it would be a good idea to check the valves clearance etc . I timed the engine on TDC with the magneto mark aligned as per the manual but I find the cam timing slightly odd. The arrows pointing upward are on the 1st and 15th pin as they should but with the magneto timing mark aligned they are not perfectly straight. Same goes for the arrows that should be parallel to the cylinder head casing. Is this normal or should they be absolutely perfect ?
