Default Dual sport to SM

Replied to an add on FBMP where a guy with a 2024 klx300sm that wants to trade for DS wheels. I told him I was interested and we should swap forks, brakes and wheels. Might do rear shock also but we will see. He agreed. I told him we can do the swap here at my house since I have all the tools and the experience. Should be an easy swap. I just find myself 99% of the time on the street so this will be a great way to get all the sm parts. He is going to Hawaii for a couple weeks and we will do the swap when he returns.

I have both sets of wheels and everything needed for the swap back and forth. You will probably want to swap kickstands, change your gearing and get a speedo healer.

I installed an adjustable kickstand and 12oClock labs speedo healer. I think my speedo was off something like 18%. I run 14/47 sprockets in DS mode and 15/44 in SM mode and keep the same chain. You don't need to worry about that since you aren't swapping back and forth, but the smaller wheels might require different gearing for you.

I can honestly say I prefer SM wheels, I am more a street guy as finding trails in my area is nearly impossible. The only thing is I feel the bike almost turns in too quickly now, it was more stable with the DS wheels. It's a pretty big drop in the front swapping wheels.

Cool thanks for the info!

I recently assembled a pair of SM wheels for my dual sport. While the rear is not a big difference in outer diameter (I run 140-70-17 SM and 120-90-18 DS), the front end with 17 inch wheel drops significantly. So steering geomentry is completely different and bike feels a completely different bike. And I agree with @tezzmin - steering is very sharp after DS, maybe too sharp. But I'm amazed how smooth and quite the bike with SM wheels.
I didn't change anything apart from wheels. Just made stiffened suspension compression dampening.

We are going for the complete swap. Front will be forks, wheel, brakes (caliper and rotor) with and even speedo cable. The calipers have different part numbers but the master cylinders are the same part number. We will swap rear wheels and even the rear shock. The DS as a longer travel. We may even do side stands but we will see. It will be the most complete swap as we can do. I am very excited for the swap. He gets back from Hawaii on the 2nd of June so hopefully that next weekend we will be doing the conversion.

Well the bike is stripped of its DS parts. The swap should happen Saturday. Did front forks, brakes, speedo cable, wheels, rear wheel, rear shock, rear wheel and side stand. It will be a complete DS to SM swap. I am excited to get it done.

The swap was completed yesterday. Kyle and his friend Dave showed up and I got to work. Swapped the rear tire and shock first. Everything went smooth. Then swapped the forks, brakes ect. Bleed the front brake. Then onto the side stand. This is where the two bike were different. They had different size bolts for the side stand. We had to drill the outer hole in the DS side stand to accept a sleeve from the SM bolt. Took about 5 min and everything was great. Kyle (who is 6’2” ) fit so much better on the taller DS set up. He went on a test ride and was super happy. We loaded up his bike and off they went. Then I got to work on my swap. Everything went smooth but ran into one small snag. The stock 106 link chain is too long to run with the 37t rear sprocket on the SM wheel. So I broke the chain and took out three links. I ordered a new master link and it should be here in the next couple hours. Then I can take it out for a ride. I love the look and it lowered the bike to a comfortable level for me (5’ 8 1/2”) . Also installed the seat concepts foam and cover.

Nice! I bet doing the suspension makes a big difference. That's interesting about the kickstand. We have similar setups.
