    Tiny Dirt Bike "Restoration"

    My kid's about old enough for a dirt bike, and like everything else I do it's gotta be relatively cheap. Cruising OfferUp one night I find a guy selling a big lot of JR50 parts for $75, half hour later I had a big pile of mini bike stuff, multiple frames, big box of engine parts etc... He'd put one together for his kid and this was the leftovers.


    I dug through the boxes and found that I had most of what I needed besides soft parts. Apparently someone had an issue disassembling the other engines, and these bikes suffer from the usual lack of care that comes with kids bikes because out of five or 6 sets, I ended up with one good set of cases, one good right side cover and had to buy a new left side to get ones that weren't broken. The left case came from one that obviously met an untimely end via being left outside


    About this time my boss bought us a new parts washer at work, so I got all my good parts nice and clean and along with a really nice bolt kit off of eBay I got a bottom end put together, complete with the first gear mod. For whatever reason Suzuki locks the lower gear out in these from the factory so you have 2nd or neutral to choose from. Easy to ride for a kid but kinda hard on the clutch.



    Unfortunately this is where the project kinda stalled for a bit. Turns out tanks, especially steel tanks and good seat pans are hens teeth for these if you don't wanna pay an arm and a dick for them. I'm trying really hard to not spend XR50 money to do this deal. Then I found a "good" complete bike on Offerup and overpaid for it, at least the guy threw in a helmet I guess


    Initially I was just going to get this one running and paint it. Then I started tearing into it and found the bottom of the frame ripped clean off where the pegs mount, at this point it became a very expensive parts bike but it had a good tank and a good seat pan/foam, carb and cylinder were also usable.


    New seat cover via eBay once again, factory enough for my feeble upholstery skills and plenty good for a kid's mini bike


    Tank dents fixed, stripped and painted + new graphics. "Daytona Yellow" engine enamel a little wet sanding and I hit it with some compound and a foam pad on my drill, buffed out good enough for a dirt bike


    Threw some new tires on and grabbed some new fenders and front plate from Suzuki. Kinda funny you can buy brand new OEM plastics for what a fucked up used rear fender will bring on eBay. Got the top end put together at some point too. Need to paint the exhaust and black out the under side of the tank then I think we'll be ready for a test fire and training wheel fab.

            Cool project. Lucky kid.
            Searching before posting will reduce dumb ass questions from you, but may not stop dumb ass responses from me.

              Nice job, I miss them days...
              Bought an xr50 (ridden 5 times) for $300 from a customer for my 3 yo kid 30+ now...
              Had to hide it till he was older.
              Enjoy these days.

                I tried to buy a z50 or XR50, next to impossible to find one here that has a title and isn't priced within a few hundred bucks of a new one. Most of the no title bikes are 1000-1200 or they were so modded for adult riders that you'd be in it 2k before you could put a kid on it.

                      I'd suggest a PW50 or a Honda if you can swing one, the resale is better and the aftermarket support is miles ahead of the JRs. I couldn't find one priced reasonably around here when I was looking.

                        Got the first fire tonight, been a long slow road but it's getting closer. Waiting on some brake parts from across the pond, need to figure out the clutch (not disengaging) and get a functional kill switch but I can at least make noise and fill the garage with 2 stroke smoke.

                          Found a crf50 for my oldest. Paid $1200. It had one or 2 scratches in the plastic. Cases and exhaust look new. He still needs to earn his helmet.

                            I tried to buy a few of those this spring with my 'rona bucks. They either disappeared quick or the people didn't want to put any effort into selling em besides posting the ad or mentioning they had one. Tried to hand a family member a grand for one that has been sitting 8-10 years and he wouldn't budge, apparently hanging onto it for his grand kids now...

                            Mine is waiting on his new helmet, I got the last parts I needed to make this thing safe to ride and we were going to get to destroying the yard Saturday morning when I found out that he got every bit of the giant melon genes from me. I have a youth large helmet hanging in the garage I figured would be too big if anything, barely got it over his ears before he was squawking about it hurting. Got lucky and found one on closeout, be here Thursday.

                            I did confirm that in low gear with the training wheels on it anyway it's got the appropriate amount of power and lopsided center of gravity to wheelie with me on it, did that before I got the parts to fix the rear brakes, almost plowed into the garage door.

                              Make sure you keep it even after the kid has grown out of it, if you can.

                              My boy had an XR70 as his first and I regret selling it to finance his first 85. We both have fond memories of that bike.
