Top speed on drz400e/hp!

Alright my dad has a 2001 drz400e and it is geared 1 down in the front but stock in the back, what is the top speed roughly? Also what is the top speed just on stock gearing? Last question is that how much horsepower does a drz400e have?

Cant help with top speed but horsepower is around 40.

Have you seen this spread sheet in the DRZ FAQ sub forum? Geared at 13/47 at 10000 rpm it looks like ~ 80. If you open this spread sheet and change the sprocket sizes you can look at what the values change to.

Find a flat road, open throttle, you will find top speed after about a minute.

great thought, but there are 2 problems I see here:

1.) The DRZ400E does not have a speedometer:eek:

2.) But even if it had one like the nice fancy model on the 400S, the reading would be so far off that he still would not know his top speed:smirk:

AND REMEMBER......for all of you that change your tires, the stock 400S & SM Speedometers are set up to read the speed (or what I call the estimated speed considering the error factor) using the stock tires only. If you change the tires to something other than that has a different rolling distance per 1 revolution of the wheel, you change the actual speed reading to something other than what is displayed.......get it????

Hope this helps.....but I may have only confused the issue:thumbsup:


Typical speedo error is right around 8% from my experience. After much testing with several bikes from an '04 Kawasaki ZX-12R, '04 VStrom 1k, '05 Hayabusa to my '08 Busa and DRZ-SM. They all read a higher indicated speed than actual speed. This, tested with electronic timing equipt. at the local drag strip, a calibrated radar gun, and most recently with a GPS.

All were quite linear for some reason, maintaining right around a 4.5 mph error factor.

FYI, previously, my DRZ SM on stock rubber went 100 mph while indicating 104. Last weekend with +1 rear sprocket, and a brand new 150/60-17 Shinko it ran out to an actual 102 mph, while indicating 106 mph. It seemed to be bumping off the limiter at that point.

I don't see why the other model wouldn't be very close to that. Most nudge "the ton" in stock, or very near stock form.

I have an S model with E stock gearing on it. I hit 83 on the speedo I think it would of climbed another couple mph if I had kept the throttle open but it was about there. So with compensating for the error in the speedo I would say 80 mph is about it . If you are down one tooth from stock on the front you are probably around 75mph top speed. With the S gearing I have seen 95 on the speedo but it would not hit the limiter it ran out of power first.

Well, as you know, Top Speed threads are almost as fun as Oil Threads and What Tire is Right for me, etc.

But, I shall continue...

It is such a simple question, but such a complex, difficult question to answer accurately.

One must take into consideration many things; Altitude, Wind, elevation changes, frontal area (how well you can tuck), jetting, air pressures, bike maintenence, etc. etc. etc.

One true way to find out. Go do it. Then again, it will be different from one pass to the next, no matter how hard you try to be consistent when it comes right down to it.

Easy answer for now; They'll do "right around" 100 in perfect conditions out of the box.

As Brakelate stated, top end varies. For instance, his white 09 SM is faster than my black 09 SM by a considerable margin. Part of the advantage he has could be aero as I am much fatter than he is. Also I have a Corbin seat and Clark tank, but, his stock mirrors compared to my bar ends should cost him a couple of MPH top end. We went for a little ride on Hwy 33 up out of Ojai and the other bike was a 1966 Velocette Endurance 500cc single in stock trim. It belongs to my little brother and yes, he has dog ears on his helmet. It is interesting to note how few RPM the Velo turns as it passes Brakelate. And, although the DRZ's could perhaps match the Velo's top speed, they were wrung out and the Velo was cruising. Brakelate is on the white DRZ with the red leathers. The video is a bit over 20MB but the quality of the GoPro is not all that great so I try to render the videos in as high quality as the Microsoft Movie Maker allows. I believe that Brakelate hit 98.6 on his GPS on the final top speed run, but, obviously I got nowhere near that speed. My bike can do 92 or 93 actual MPH top speed. The Velo can do the ton according to my brother but he is a sand bagger so, who knows?

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!
