I just recently put my DRZ400E on the road. I also just recently bought a new back wheel, because my hub on my other was bad! :ride: Anyways that wheel came with a sprocket on it which is a 49 tooth, my other wheel has a 45.

Then I also have a 13 tooth front sprocket, I know stock gearing is like 14/41 or something of that nature. What I was wondering if 14/41 would be enough to get me to a least 70 with 5th gear still having enough space to rev out. (or engine speed not so high.)

The gear range on there I have now only gets me about 60 and thats maxed. (13/49) What do you guys run and is your engine speed in last gear low or mid? Or what would be the best gears to run for the street, but could also be used on the dirt as well? Thanks for your time in advance. :thumbsup:

15/44 is stock on the S which has the same size wheels as your E. 14/41 is the same as 15/44. 14/41 should get you to 90+ on the street, cruising at 65 would be easy.

I find I'm changing the ratios when I ride street and dirt. 14/44 for street, some highway but mostly back roads, no freeway. 14/49 for dirt.

Here's a link to a gearing spreadsheet in the FAQ. You can change your front/back gear size and wheel size to see what rpm and max speed you will get for each gear.

14/47 is OEM on the E I use 15/47 works best for half and half just cant fire down the freeway at all.

I got 15/38 on 17 inch rims and works great on the street. I do about 130 miles per day.

I have stock gearing on my s. It works fine on the freeway, won't go any lower myself. Off road it's okay unless your in really technical stuff, like going over fallen trees or through a thick woulds.

I'm running 14/44..... good for the many miles of FS roads we run out here.... would still be a bit low if I spent more time on the pavement.

15/44 isn't going to get you low rpm cruising at 70mph. I'm running that now and it does well at 55 but going up to 70 revs it out quite a bit. 15/41 would likely be closer to what you want......

Man this all depends on mods and weight. I am a fatty and i am running 16/44 and 70 is ok at hwy speeds. I am dropping another 3 in the rear.

I run 15/47. Sometimes in tight and/or hilly stuff, other times on 2-lane paved, but never highway. Sometimes I wish the gearing were lower and other times higher, so I figure 15/47 is the best compromise given the DRZ's lacking 5-speed.

FYI: With stock DRZ400E rubber, in 5th gear, speed in MPH = engine RPM/100

Example: 55 MPH = 5500 RPM, 65 MPH = 6500 RPM, etc.

I have 2 sets of stock wheels one for mild stuff and road and one for dirt. I have tried a few sprocket combos usually 15/44 for road and 14/48 for off road. I would like to try 14/ maybe 38 for longer road rides on higher speed roads. Anyone tried a high speed gear ratio with good results?



15/44 is stock on the S which has the same size wheels as your E. 14/41 is the same as 15/44. 14/41 should get you to 90+ on the street, cruising at 65 would be easy.

How does the 16 fit on the bike as my 15 looks like the biggest that can fit the DRZ without scraping the swing arm or cash chain guard?

Some squeeze the 16T on with some modification...I purchased a 16T with intent to do same and then decided against it after attempting to slide it into position...:busted:

15/38 or 39 is reasonably good for highway stuff....As far as I'm concerned if your bike can't pull peak power in 5th on a flat road it's gearing is too tall...:thumbsup:

BTW...the more grunt your engine produces ,the taller the gearing it can support...:smashpc:

I recently plated my E and decided it was so fun to ride on the road that I bought the Warp 9 SM Kit. It came with 15/45 and although it ran quite nice, it was still far from highway comfort. I can easily keep up with traffic on NE backroads and roll it on for brief periods to get me grins. I just changed to 15/42 and I'm currently working on the jetting that Craigo suggested to me in an earlier thread and I'm a yoshi pipe. I'm 285 lbs and very excited. This is more fun than my VStrom DL 1000. When i get it back on the road I'll report how she rides...although I don't think hard core dirt riding (for this bike) is in the future anymore.

I run 15/43 after changing gearing 4 times.

Thanks I thought the 16 might be a problem. I was thinking of getting a 38 rear and then trying it with my 15 front and 14 front. 15/38 should see some good top end speed and low revs at 110kmh

Are you basing the above on YOUR 15/47 gearing, or stock (E) gearing of 14/47? That seems to be like my 14/47 speeds/RPM.
