    Around 1980 I used to visit the local metal scrap after hours. I pulled this frame from the pile and carried it home. I found shocks and other parts on subsequent trips. My dad welded on a piece of pipe to the stem because it was used so much without the right parts the metal was curling. I painted it black, put a headlight on the front and it was one badass bike. I sold it before I went into the military, great memories. Thanks for the video.

      That bike sounds epic! Love how you turned scraps into something so cool. Who needs a brand-new bike when you can create a legendary ride from scrap? Sounds like you were the original DIY master! Thanks for sharing your story!

    Best bike I had as a kid. I wish I still had it! Great video. I chose this over a motorcycle. 😊

      Choosing a bike over a motorcycle? Smart move! Less chance of getting a speeding ticket... unless you're racing the neighborhood kids!

    Great memories of time on mine with my friends after school in the early 70s...the forks always leaked so i did buy comp forks that cost 100 dollars...we learnt how to bunny hop and spin on the front wheel ...180s in the air..huge jumps...long before flatland and freestyle came along...and the bike never let me down...thanks for the memories...cheers !

      Very cool! My friend down in Texas told me they used to convert the forks to air shocks! May try that if I find another Yamaha Moto-Bike.

    As a teen I was bought a 1975 Kent KMX 750 kinda like or the same you had. A few yrs later it was stolen from a friend. I tried finding another but no luck for a long time then skipping a few yrs later I saw on better one on eBay. It came with all the plastics and now I still have it. 👍

      These old suspension bikes are just cool in every way! My friend had a Kent like yours. I have a Graco as well, similar but with a 22" front wheel. It was a gift from my parents on my 13th birthday. Still have all the parts and plan to restore it soon!

      @@RadMattic yes indeed, at the time I own the 1st one I didn’t even know anything about them and thought it was the coolest thing ever. I rode it through the low train tracks cause it was confortable enough and cool. I have another frame and I’m tempting to put a 2 stroke 66cc motor to complete the image of the bike lol. We’ll see.

      that's what i had too . I'm pretty sure it the same bike as depicted in this video , just rebranded to Kent.

    nice rebuild . i hade a bike very similar to that , i would snap those spindly front axles all the time.

    • @RadMattic

      Thanks! I feel your pain-those spindly axles are like the fragile eggs of the bike world! One wrong bump, and *crack*!

    Very cool video! Thanks for doing it. Brings back some great memories.
    Pretty funny to see cartridge bearings in the shock mounts, but not in the swing arm! If there's ONE place where quality bearings are necessary, it's the swing arm! Oh well.
    (That probably partially explains why it rode so bad when I tried on on the playground in about '77. Like riding with flat tires in sand!)
    Personally, I really like to degrease parts & give a bike like this a thorough washing BEFORE tearing it down. Much less to clean and more fun while working on it.
    I have a mid-80's Nishiki waiting for me to restore... better get off YT and my butt and get to work!!!

    • @RadMattic
      @RadMattic  28 дней назад +1

      Sounds like that playground ride was an adventure! Who knew a swing arm could feel like a trip through quicksand? Good luck on your restoration journey! And, thank you for the great comments! You are so right on that swing arm! When I raced the bike at Dirty Fest it was the squishiest, bendiest ride ever! I'm amazed it didn't throw a chain. I'm working on a 1976 Huffy Monoshock video next. Trying to wrap up the editing over this weekend. Actually filmed it over a year ago! Have a great weekend!

    The chain on those stretch so easy. The need a deraileur guide.

    • @RadMattic
      @RadMattic  2 месяца назад

      That's for sure! These weren't designed very well in the beginning! For any serious riding or vintage racing, they need a good chain tensioner! But for vintage bikes shows, a modern chain tensioner would be a party fail!

    I remember seeing a 1 or 2 page cartoon ad for this bike in 1976, in MXA (Motocross action magazine), when I was reading about Bob Hannah.
    Well, I'll be. 1:49 in the vid. That is Bob Hannah drawn in on the background of that ad. #39 in the 125cc Motocross Championship.

    I am right down the road from you in St Joe. I have a 76 hanging from the ceiling in my shop. It is mostly intact minus the wheels. If you know anyone looking for one let me know. I got one for Christmas in 1974. I don't know if I can find the parts needed to restore it. Great video

    So nice the way that you restored the wheels, so much better than changing all.

    • @RadMattic
      @RadMattic  11 месяцев назад

      I think so too! They are a bit rough when you see them up close. Especially the rear wheel. But I think it is cool to have the original parts!

  • @robbchastain3036

    Fantastic work and you mentioned at the end that you want to ride it on a downhill track and that was probably the intended purpose of this fully suspended bike, no? And I saw in the magazines back then, and here on RUclips now, some of those downhill tracks and they looked insane. In San Francisco in '79, I competed in an NBA race at a downhill track in a city park and it was fun tho' not particularly wild, at least not compared to the big air the riders were getting on tracks down south. And thanks for restoring and upgrading this Yamaha Moto-Bike and wow, one has to wonder why Yamaha and Kawasaki didn't build on their early success with successive lighter-weight models and even pro-class bikes. Still, kudos to both for their production bikes and promotion of the sport, especially Yamaha with that Gold Cup series, the stuff of dreams, kids racing their Sting-Rays on a track in a football stadium, incredible.

    • @RadMattic
      @RadMattic  10 месяцев назад +2

      Thank you for the kind words and great story! Nothing is better than those old downhill BMX tracks for sure! You should go to DirtyFest in So Cal, or Frogtown in Nor Cal this year. You would love it!

    I’m a mountain biker ex Bmx dude now I just collect big Bmx bikes-I saw the challenge you had on the race with the pedal bobbin I spose if you were able to put some sort of adjustable suspension and firm up the ride, you would still get that plush ride yet less pedal bobb when you race and will mos def get you some pedaling gains….just a thought🤷‍♂️

    • @RadMattic
      @RadMattic  3 месяца назад

      You might be onto something! Who knew that a plush ride could also mean less bouncing around like a bobblehead during a race? I do have a few secret tricks that limit the amount of bouncing!

  • @dand3975
    @dand3975 Год назад +2

    The color is just fine looking. Better with a tuff powded coat that is a shade of yellow off, than a perfect color match sprayed on that will eaisly chip and get scratched. How about a set of light weight wheels, modern light weight seat and post, and carbon handle bars to save some weight for vintage races. Save the orig parts for display. ll in all a cool restoration project.

    • @RadMattic
      @RadMattic  11 месяцев назад

      Interesting that you should mention these upgrades! There has been so much interest in racing these old suspension bikes. Some of us have been upgrading and modifying our bikes and now, they have split the racing into "stock" and "modified" classes!

  • @joecamp8824
    @joecamp8824 5 месяцев назад +1

    What end advantage did you get by changing the gear ratio on the rear wheel? I had one for Christmas '76 and I remember it being very fast with the long crank arms and the orig gearing. To a ten year old kid this was a beast of a bike. [stolen from me in 1980, recovered later but vandalized].

    • @RadMattic
      @RadMattic  5 месяцев назад

      Oh man, the stock gear on the back is huge! It's a 20 tooth cog! Switching it out for a 16 tooth was a must. With the 20, you will spin too much after the first few pedals out of the gate!

  • @smwintry

    Hello ,, Great bike !! What length cranks did you put on it ,, I am restoring mine , that I have had for 45 years !!

    • @RadMattic
      @RadMattic  11 месяцев назад

      Thanks! The cranks I used are 175mm. They are 1990's White Industries mountain bike cranks. They're actually a bit too long for the BB height, so I plan to switch them to 170 mm early 80's Dura Ace cranks, eventually!

  • @user-esprit1086

    Now I'm not saying you are wrong but why do america and I believe numerous other countries have the front brake on the left if the handlebar and the rear on the right

    • @RadMattic
      @RadMattic  9 месяцев назад +1

      I've heard that it's the reverse in Europe. If I rode with brake levers on opposite sides, I'd flip over the bars for sure!

    • @dudeonbike800
      @dudeonbike800 29 дней назад

      That's good question. I'll have to research that. I assume it's because most people are right-handed, so put the most-used brake on the right side. But TBH, the brake that needs the most strength and proficient modulation is the front, so one could argue the front brake should be on the right.
      Yes, Europe bicycle cables are reversed. Matches motorcycles with right side being the front brake lever.

    those forks were heavy and bouncy but at leat they didnt fail after 2 seasons like nowdays. I wasted so much money on rear shocks on my ebike, that i would love to have something not so smooth but more robust.

    • @RadMattic
      @RadMattic  4 месяца назад

      Sounds like you’re looking for forks and shocks that can handle the rough and tumble of the trail-and maybe a few dance moves too! Who knew ebikes could be so high maintenance? 😄 Thanks for watching!
