Has anyone ever built a bike from scratch?

Edited Date/Time 3/26/2022 10:13am
I got the idea from MotoRoss678 who built a YZ250 from scratch in the bike builds section, really nice build!

Anyone ever done something similar? Started with just a frame/engine and eBay’Ed your way through it? I was thinking about doing something similar with my KLX110 since it seems like the only thing left stock will be the bottom end, frame, and suspension. All the takeoffs are thrown in boxes so I’d have to see just how much would be involved.

I actually pondered this back in the 90's when i worked at a bike shop. Honda offered new motors in their red book, which weren't crazy prices, but i think piecing out the rest was pretty ridiculous. Obviously, this was building with all brand new OEM parts and certainly would be cost prohibitive to say the least, but it was interesting. I checked a few years ago and any of the golden age two stroke motors were long gone.

I bought this 03’ CR250R as a frame/forks/shock for $400 in 2010 while I was attending MMI in Phoenix as a broke 20 year old. I found a bottom end that needed rebuilt, and separately a cylinder that needed plating for another $400 total. I would purchase things like beat up wheels, break them down and lace up new hoops. Really built the bike from the ground up.

Over a few months I built it up and raced the shit out of it. I could ride the 250 and 450 classes with it and made a little money locally.

After a few months the engine grenaded, and I got a 450 to race so the bike sat for a while blown up. I ended up stripping it back down and doing a full build up, then ended up selling it for like $5,000 😂

Sometimes with restorations you nearly end up building the bike from scratch anyway. A couple of mine definitely feel like they've been built from scratch after buying new suspension, fuel tanks, air boxes, cases, cylinders, radiators, seat pans, wheels/hubs/tires, carb, plastics, bolt kits, and nearly everything else except the frame and swing arm.

I have and like Bomber said that’s pretty much what a lot of restorations turn into anyways. You should do it. Less parts laying around taking up space after.

I like all the answers so far. The nice thing about the 110s are that most go all out building them, so I should be able to snag some Larger OEM parts like suspension and a bottom end relatively cheap.

That’s a good looking bike! Great story.

I’m currently building an rm125 from scratch. All my parts are a mixture of 01-06 rm125 and rm250 parts that were all purchased from eBay and Craigslist. I have an 01 rm125 frame with an ama tag, an 03 rm125 motor, 02 rm250 swingarm and linkage, 04 rm250 forks and clamps, 03 rm125 wheels, 02 rm125 subframe with an 04 airbox, and 06 rm125 calipers.

I built this, from a rag 94 cr125 chassis, and a 90 engine and wheels. Went through the engine, new rod, replated cylinder with Eric Gorr 144 kit. Obviously bought some new stuff. I also built the 95 Honda of troy tribute 250 from boxes of extra cr250 stuff I have.

Sky is the limit bud, go for it.

Not from scratch. But this 500 I build a few years ago had brembo brakes, KX 450 trees holding yz KYB forks. KTM wheelset and pegs.

At the time I was considering building my own 4130 Chromoly frame to utilize any shock on the market.

I intend to ‘bastardise’ an XR600 one day. BIG desert tyres, no silencer, flat seat, ‘round’ ‘triumph’ style fuel tank.

Does this count? I've got it totally apart, but a divorce and a move slowed me down.

I built this RM370 over the winter. Started around Christmas time.I only used the frame, lower end, and rear wheel off the original bike. Almost done with a 76 RM125 too, which I started after the 370 was done. Ebay and partzilla for most of the missing parts.

Has anyone ever built their own frame? This is the only one I have seen (made for fmx - so doesn't really count)

Not sure how much this qualifies but....

The last bike I had was a brand new KX85 (2001 model) and I was a support rider for Kawi/Pro Circuit. Right when we got the new bike we stripped it down to the frame, had the frame painted Flo Green. Sent the engine and suspension to Pro Circuit, then once those came back we put it all back together with all the upgrades. Works pipe, shorty muffler, Hinson clutch, PC mag cover, Renthal sprockets, bars, all different plastics, Bridgestone tires, black Excel rims, maybe more stuff I can't remember but it was definitely awesome to tear a bike down to the frame and rebuild it with all the goodies.

Go over to the Old School Moto site. Thats all we do.

I feel like every time I look at this bike I lose ten minutes of my life.

There was a rider in the 70’s or 80’s that built his own “works” bike, but I can’t recall all the details. One of the magazines did an article on it looking back…MXA I believe.

Some of the bikes I restored I would have been better off starting from scratch! Very fulfilling to build a bike from scratch but usually very expensive also. If you want a certain bike bad enough you will do whatever it takes…

I see both sides of this. Sometimes it’s nice to take time and clean old parts and fix imperfections as much as it is to buy all the new badass upgrades.

Just watch some of these Indonesia motocross shops. Bikes are expensive so they often take parts and build frames and swingarms all by hand. This is how much they love moto loads of these videos.

Yep what you mentioned plus fenders and shrouds, ufo now sells them so much cheaper than the oem and need a seat, a handfull of new bolts and such. Watch out for the seat bolt, 23 bucks ha ha.. think i spent 1200ish total. I also put on 21 triple clamps etc...

Back in the mid 2000's I built (3) 250 2-strokes, getting all the major components off ebay. Back then places would part out new or near-new bikes (because the bike shop's couldn't hardly give away 2-strokes!). They were worth more as parts, than a whole bike. I'd get most of the bolts and small stuff from the dealer, new, to put it all together. On a 2001 CR250 I built, I found a mint frame on ebay - was the only bidder and got it for 50 cents! (shipping cost me $50) Fun times! Also built an '06 RM250 with A-kit suspension for $3500 total. I still have those bikes...
