I have tried responding to other posts where people have been discussing lowering their Duke but haven't received a reply so I thought I would start my own topic. I just ordered a black 2016 Duke 390 for my wife. She is only 4'11". I am wondering if there are other riders around that height on this bike and if so, what did you do to make it work. I am ordering the 60mm lowering shock eye, plan on softening the rear shock, and getting her some height enhancing riding boots. Any other suggestions? A little concerned that after all this it still will not work for her.

KTM Powerparts makes a lowering kit, but keep in mind that if you upgrade to the PP seat down the road it's 20mm higher than the standard seat. The lowering kit should get her "comfortable". I have a 30" inseam and I'm not on tiptoe. You can get some rearward rotation from the bars but not a lot unfortunately unless you just replace them. The factory bars are a weird diameter so you'll need to swap the risers also. We do have plenty of shorter riders here who've made the bike 'work' for them.

PS - tell your wife to mind her knees. Men generally have stronger upper bodies, and women stronger lower bodies. We tend to "handle" our bikes with our legs when using our bodies instead of the engine (i.e. when moving, parking, mounting/dismounting etc) and it's all too easy to put stress on your knees, especially if you're shorter.

Thanks for all the the replies.

mejetski2000, I've seen the KTM lowering kit, however that only drops the bike 25mm. I am going to order this kit that drops it 60mm.
KTM 390 Duke Lowering Kit -60mm
When she sat on the bike, her feet were a good 3 inches off the ground so I am going to need as much height reduction as possible.

hansolo_uk, that is an interesting tool to see what your riding position should look like. Unless I have her inseam horribly wrong though, this tool shows her touching with her toes and she wasn't even close.

retrochick, thanks. I have read her suggestions. My wife gets irritated when 5'2" women say they are short. She says they don't know what short is:)

At best I think I can get this thing lowered about 2.5"-3". I will be going to pick up my bike next weekend(about 2 hours away) so I will stop by the KTM dealership which is in the same area with a couple of 2.5" blocks to put under her feet and see if she can touch.

Anyone have a picture of an under 5' rider on the 390?

Thanks again everyone.

You will need a shortened sidestand to go with that lowering kit, and should raise the forks in the clamps at least an inch. Lowering just the back will slow the handling down considerably. As for the reach to the bars, the 390 is the shortest bike I've ever owned. I doubt that will be a problem.

I have a Velocette club friend (our newsletter editor) who is under 5 feet tall, and when she sat on our 390 it was the same thing. She rides to work, has for years. What fits her? A Buell Blast. She has worn out two so far!

Since I had a hard time finding any answers as to whether the Duke could be configured to allow a 4'11" rider, I thought I would respond with some pictures of my wife on hers. It can be done and she is loving the additional power over her old Ninja 250.

looks like a great result !

did you just go for the (60mm?) lower shock mount or have you also raised the forks in the yokes and shortened the stand - I tried studying the pics....

Sorry, should have provided some details. We installed the 60mm lowering kit from Procycles - BMW, KTM, Suzuki, Triumph - Motorbike Sales Sydney and raised the forks 20mm. The kick stand in the kit is not short enough for that much of a drop so we took the stock stand and had it cut down and welded.

I'll post up more updates in the spring after I've had a chance to ride the bike but I've now lowered front and rear of the bike by ~45mm.

T-Rex Racing lowering link in the rear, which can be ordered with their shortened kickstand, plus modifications to front fork internals, similar to the OEM KTM lowering kit option. The fork modification reduces the fork extension/travel by 25mm, making it 125mm travel. Combined with raising the fork legs in the triple clamps by ~17mm, the maximum I would do based on fork leg finishing (smooth portion of leg entirely within lower clamp), the front is dropped by ~42mm.

Dropping the rear alone by 45mm with forks raised by 17mm didn't give my 5'2" wife enough comfort, was still on toes, not tippy, but toes. Now with the additional 25mm drop in the front, she can properly get balls of feet solidly on the ground.

It's considerably lower than stock and geometry is as close to stock as possible (lowered equally F&R). Bike had to go back into storage without test ride unfortunately so I won't know until the spring how the overall lower ride height will behave on the road, over speed bumps etc.

Thought I'd commented this thread previously, but appears not. T-Rex Lowering kit review here: http://www.ktmduke390forum.com/forum/appearance-modifications/33449-t-rex-racing-45mm-lowering-kit-review.html

Hi There,

I know this is quite an old thread, but I'm curious about how your wife liked her Duke last season? Were the mods a success?

She looks lovely and happy in the photos ;)

If the question was for rssniff, he hasn't been on the forum since April of 2017 so unfortunately no updates since.

On our end, my wife was pregnant this past year, with baby boy born last October, so she hasn't ridden the lowered Duke yet.

Overall, the lowering on our Duke has worked out really well with a fairly balance drop F&R. However, as it was lowered quite a bit, it did end up with less ground clearance and I ended up touching the engine case down at a track day last fall. Wouldn't be an issue on the street but it was a liability at the track. I'll raise the bike up again before taking it to the track again :D

Hi! Yes, my comment was meant for rssniff...I'm not sure how I did that, however, thank you for responding!

Congrats on your new baby....I bet your wife is anxious to get on her new Duke this year! I was mostly curious about how rsssniff's wife liked the Duke in general as a smaller rider. My Duke is not lowered, and actually has the aftermarket ergo seat on it that adds about 3/4 inch. It suits me well with a 31" inseam...about 32" with my riding sneakers. I'm glad I didn't have to go through the extra effort to adjust anything!

When your wife gets on the Duke for the season I'd love to hear what she thinks of the little bike.

Thanks!

Haha, oh my mistake! I see that the Duke is not just her bike, but that you share it ;)

I'd still be interested about how she feels about it once she tries it out!

Sorry, hadn't been on here in awhile. She loves her Duke, and the ride height is pretty good for her. At 4'11" the choices for motorcycles is pretty slim. She would have a new 2017-18 390 by now but they made the new Duke taller and we're a little concerned about how low we can get it. I want her to test drive the new BMW 310 to see if it is enough power compared to the 390.
