Turning a Harley Davidson Sportster into a Dirtbike!!! (Part 1) 

Like a KTM 690?

Thank you, I’m excited to make more content and post more builds in the future. Hoping to update parts of this build series every 2-3 weeks

Finances are hard but hey man the knowledge comes with just trying something out. You won’t learn if you don’t try!

I will be pulling it back in soon for part 3 but need some more parts for the next part.

Thanks man, a lot more to come but I will be uploading more as it goes along

Yes there are, but the ones seem to be a different style units. I have a hayabusa front end converted using xs650 bearings and a custom axle for a tracker but it’s a little shorter than I would want to go

I hope it’s a big bore 2 stroke 🤘🏼

So trees may be easy as a shim and taper bearing but off hand I do not know. These husky trees are as cheep as 150 on eBay

@@SlappysGarage For sure. Thank you for replying.

Yes, I would love to do them a lot faster but I need more money to fund the build. After my next 2 videos I should have enough parts to get back on track with the dirtster

I still think a trike using an atv rear suspension would be a blast

@@SlappysGarage For sure. Had a friend of mine owns a salvage yard and a Yamaha fzr or something come through. Made a racing 4wheeler out of it. 110mph in third gear. Was a six speed. No one ever got it out of third. Widow maker that one was. Anyway, trike would be super cool of course. I was thinking 4wheelet for the unusualness of it. Not the fat tire type but the independent long travel front end types. Like a banshee frame.

@@SlappysGarage I like building off the wall things. I also want to do a lifted Harley golf cart.

@@scottfree8848 sounds like a fun build. Those old yfz rollers go for cheap would be a good start

@@SlappysGarage when I was a kid I had that toy called a big wheel. Rode that thing everywhere. Gonna try and design me one that's street legal and looks a close as I can get it to look and be an adult size big wheel.

I bought a wrecked TR 650 and these trees stayed on the bike. They milled out the tree for the legs to fit. But I think it was in the video the yz426 forks swap over into these trees

I’m going to orient express to revalve and stiffen the front end. I’ve read about guys running yz426 suspension on tr650s which are 406 lbs as an upgrade from stock.

@@SlappysGarage thanks so much for the response. I’m going to get the stiffest springs I can find and heavier weight oil. I’m not going to be doing anything crazy with the bike but it still needs to perform.

If you ain’t trying, you ain’t learning

@@SlappysGarage Good attitude! YOU'LL do fine. If you come to Sturgis, stop by and have a look at mine.

I had the idea to extend the swingarm 1-2 inches but for the amount of work to do so I’ll wait until o test ride it first. It’s also a concern that the knob is tire will hit the swingarm

Should be able to slide the tubes down in the front and make a linkage for the rear if it has one

I direct messaged his instagram

While you are not wrong ground clearance and rider position are my big concerns when I want to hit hill climbs and any jumps I can find

@@SlappysGarage I understand completely. I don’t know how old you are or if you ever heard of the TV series “ Then Came Bronson” from the early 70s. If you’ve never seen it you should look it up. We used to chuckle how he could do anything with that Sportster albeit in some scenes it was a Sprint. He could even pound out bent fenders perfectly with a rock.

@@oldamericaniron5767 this is my first time hearing of that but I will check it out. It sounds like he knew how to get rowdy and have some fun!!

Yup, until you tuck the front end. Then it feels like a street bike as you’re trying to pick it up.

They are kx250 tubes. I had the front end off another bike I bought they were milled to fit the tr650 trees.

If you have instagram a direct message on there slappys_garage
