DRZ400s sprockets modify

Recommended Posts

just getting into riding some steeper single traks and find i'm bogging down enough to want to change the sprocket configuration....any suggestions? heard its best to use a drzE combination, others say going down to a 13 front would be good enough...is there a combination that would fit the chain i have now?thanks

Front sprockets are cheap, drop to a 13t. If you like it, loctite it and ride for a while. Don't over think it...make the cheap change and ride. IMO.

13/48 for single track, 15/48 for dual sporting, 15/44 morading around town. Have a 14 too but not much call for it between the 13 and 15.

14/41 here and it is plenty powerful enough for single track and still gets me up to 65 but it's a bit buzzy.

If you have the standard 112 link that comes on the S you can fit 14/47 no problem. I just put 14/49 on my S (I haven't had a chance to try it yet) and it just barely works with 112 links. Requires the adjusters to be all the way forward.

It depends how slow you need to go....Just keep in mind the lower you go for 1st, is going to bring your 5th gear cruising down along with it...

Maybe try 1 tooth lower on the CS and see how that works for you..

assuming you are starting with stock S gearing, going to E sprockets vs. keeping your current rear and dropping to 13 in the front will be about the same from a gearing standpoint.

stock S gearing is 15/44 for a gear ratio of 2.93

E gearing is 14/47 for a gear ratio of 3.36

S with a 13T front is 13/44 for a gear ratio of 3.38

the E sprockets might be a little easier on your chain, though. the smaller the sprocket gets the tighter the chain has to bend to get around it. i don't know if it really makes much difference, but, in theory at least, it could cause your chain to wear more quickly.

(i run my S at 14/44 which helps a bit relative to stock gearing on single track, but still lets me cruise at 70mph on the highway without problem. i would like to go 14/47 for off road, but am a bit hesitant about what it will do to me on the highway...and i end up riding a lot of highway. i'll probably try it out at some point, though.)

You can do a 14/47 sprocket set-up without changing the chain. I did and it gave me the grunt I was looking for without too much loss for the highway.

I went to a 14 front on my S about a month ago and didn't realize until a couple days ago that the rear is a 45. My commute is around 60-65 mph. The 15/45 put me right in the bad vibration zone at this speed. With the 14/45 the little raise in RPM makes 60-65 much smoother in the footpegs and handlebars.

I took a small step and went from 15 front to 14 and it made a big difference on my S thinking about teh 47 in back but happy for now.

      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 ?

      My bike was stolen, so I'm liquidating my spare parts. 
      I took this off my S and replaced it with an SM unit so my speed would be more accurate with the street wheel setup.  I no longer need this spare.  I greased it regularly and it was in good working order when I removed it.  Included is only what is pictured.  Cable not included.
