Ktm lc4 400

I'm looking to re-gear my 95 LC4 400 for more off road riding. The only "road" riding that I will probably do is dirt roads. Any suggestions?

Not real sure what the rear sprocket is at the moment, but I'd like something a lot more down low power. The bike will do 20 mph in 1st gear right now.

Please don't take this the wrong way.

You need to:

Know what sprockets are on your bike now.

Know what the stock sprockets are/were.

Read/research/understand the effects of changing the tooth count on each.

Understand how the required chain length will be affected.

Then you'll be able to:

Know if your bike has a strange/extreme set of sprockets on it now.

Know what reasonable combinations are generally used on your bike.

Realize that combinations well outside the norm aren't used for good reason.

Know that front sprockets on dualsports/dirt bikes generally range from 13 to 16 tooth and rears are around 48 tooth.

Know that since front sprockets are much less expensive than rear sprockets, it's the front sprocket that is usually changed to raise or lower the gearing.

Or just try 13/48.

Don't take this the wrong way...

I know how gearing effects how bikes perform. I've re-geared my road bikes many, many times. I understand if you go smaller sprockets a shorter chain is needed and if you go bigger sprockets a longer chain is needed. This isn't my first rodeo. Just because I'm new here doesn't mean I don't know what I'm doing.

I have read through many many pages on this forum already but haven't come across anyone with a similar bike or similar riding interest. And from what I've experienced so far the search thread option is worthless. One word searches don't turn up anything, on my desktop or talkatap app.

I'm just looking for opinions on what works best on a similar bike with similar riding styles. Because I know it's going to be greatly different than what I have now, 20 mph through the woods is way to fast.

On a 620 RXC... 15/45 for the dirt, too tall for single track though...

I went from 14/50 to 15/45 recently on my rxc 400, the 14/50 was great off road but the lc4 shook like a banshee at highway speeds. My 400 is set up more for dirt road touring vs. hard singletrack...
