  1. @johnnym Thank you, I’m glad  you like it. The bike from GTA reminds me on a Honda. Full fairing ...

    Forgot about that: At first I wondered about that knob drive for your engine, but later understood why it's a really good idea: Because in reality it's also the engine that drives the wheels and not the wheels that drive the engine. And IIUC it still also works the other way round like in all existing LEGO TECHNIC motorbikes so a feature missing on a lot of motorbikes (LEGO sets, MOCs, mods, etc.).

    Thank you for making it clear again, at least for me. At first I tried to integrate a speed gearbox, but I was unable to find a proper place for the shifter. So I decided to go for a functional gearbox, which is working the opposite way. That gave me some headaches ...

    By the way, I added this feature to all my Lego motorbikes.

    • Front and rear suspension
    • Steering
    • 4 cylinders inline
    • Functional gearbox (not speed)
    • HOG engine / rear wheel drive

    The black gear on the right side is to rotate the motor and on the left is the knob to connect the engine to the rear wheel.

    Please note, that I ran out of time and I will try to upgrade this build. Check out the topic for any updates.

    Technical fun facts:

    • 4 cylinders inline, 1400cc, 126hp, 124Nm

    Good Luck to all contestants.


  3. Bad news. I’m running out of time, so I will enter this contest with an unfinished build.

    TC19-21.jpeg

    You can see I made a step back to a traditional fork system instead of a swing. I tried a few things, but none satisfied me and time was running fast.

    I’d call this build unfinished because I didn’t had the time to add more details. There is still no stand, no front fender, flashlights or mirrors and so on.

    I’m still not satisfied with the current naked edition or my fairing versions.

    However, I will try to finish this build after the contest while I think the base is good.

    Good luck to all contestants!

    I'm not sold yet on the fairing... I liked the naked look with the wide, bulky gas tank A LOT, although (as mentioned by others) it is a bit heavy in the belly like that. Maybe keep the fairing in the bottom, but lighten up with the fairing on the sides. Right now they mess up the clean declining line of the LBG beams, I think that should be a primary characteristic to show of instead of hide...

    Thank you for being interested in my model :wink:

    I’m with you, I’m also not sold yet, but it’s the best solution I found so far. This beast is almost as wide as the TC18 entries - 11 studs with fairing and 13 without!

    However, it’s the night before deadline and still a lot to do. Man, I’m soooo late this time, but please have a look by yourself:

    TC19-015.jpeg

    You can see my current stage for a front swing. It’s still WIP, but it works generally.

    Still need a front fender, kick stand and more little details. We’ll see how far I can get tomorrow ...

    Puh!

    Looks like a beast of a machine! :thumbup: Looking forward to the next step.

    Thank you! :blush:

    I always vote for keeping a motorcycle naked, so that's the way I would go.

    Same with me. And you’re also right, a little dress could make a bike look even better. But sometimes bikes need a full fairing.

    So I want to show my progress with a fairing:

    TC19-011.jpeg

    I’m still not sure if this will guide me to something ...

    TC19-012.jpeg

    What do you thing?


  6. I was very productive yesterday. Please excuse the poor picture quality.

    Tc19-005.jpeg

    As you can see, I changed the main color. In red are simply more parts available.

    TC19-006.jpeg
    I also recolored the motor and added some carburetors and exhaust simulating liftarms.

    TC19-007.jpeg
    The gas tank was more a placeholder because it looks a bit blocky, but I like the general shape. So I tried to fill the gas a bit and it turned out quite well I think.

    TC19-008.jpeg

    Beside the seat the swing arm found its final shape. There is the rear fender and some guard for the chain, I don’t know the name of it.

    TC19-009.jpeg
    Please excuse the really bad quality of this picture. I only wanted to show this side of the bike. Besides the rear brake disk is also the L lift arm as a brake caliper and its holding part.

    Next step would be a proper front! I’m also not really satisfied with fork angle but I think it would be almost impossible to change. Maybe I will use the Olson shocks instead of the Ducati ones.

    And the main question: will I be able to create some fairing or leave it naked?

    I do not agree with that.

    I think @MegaRoi 's idea is cool and add a real + to the playability.

    Based on the last picture of the first post i would: (looking at the picture from left to right):

    - keep the first axle with the 16T and tan 20T gera as it is;

    - The second axle (between the first one and the one with the driving ring): remove the 12T gear on the left and place a 12Tbetween the two tan 20T gears;

    - On the axle with the driving ring, replace the tan 20T by a Blue 20T worm gear, and try to implement the new driving ring, if not, the blue 20T won't mesh.

    You'll get a functional 2 speed gearbox with neutral point, and, according to your basic idea, be able to see the difference of speed at the wheel between the two gears.

    Keep it up!

    S.

    A 2 speed gearbox would definitely fit, even a 4 speed could be possible. To keep it simple I tried to integrate a 2 speed with an idle gear. Somehow I couldn’t realize a working shifter including stepper. At least not at the position I wanted to have it. So I came back to this easier idea with only one and idle gear.

    I like the Framework, but imho the "HOG engine" is a stupid idea :wink:. Your space in a bike is very limited, so why waste it for something like this instead of a workin gearbox?

    Thanks for liking my framework :wink:

    The idea behind my “stupid” function is in fact to increase playability on a bike. While a car is more for the looks, a bike is more behind its root function. And means bringing the engine power to the rear wheel! So my HOG engine is more show the working engine and you can engage the power train to the rear wheel.

    At some point i simply realized that I’m to stupid to build a working 3 speed gearbox with shifter and stepper that fit to my engine concept, so I reduced it to 2 speed and a simple shifting mechanism.

    Thanks @HorcikDesigns


  8. Hi there, it’s quite a while since I’ve been active here, but I was so incredibly busy that I almost missed this contest!

    I needed some iterations to find out what I want to build and this is what I came up with:

    TC19-001.jpeg

    The build will have full suspension, something like a Deltabox frame, a simple gearbox shifted by a lever in the area of the foot peg and a Hand of God engine.

    TC19-002.jpeg
    The fork is only to find the general proportions and still WIP, same with the swing arm. I wante to have the chain inside the swing, that’s why the arm became so wide with the new wider Ducati tire.

    TC19-003.jpeg

    Another pic and a closer look at the engine:

    TC19-004.jpeg

    This is the engine I use. With a four cylinder in a row the motor builds quite wide ...

    The engine will be rotated by the black gear. This is to improve the playability. Means you can grab the model and rotate the engine to see how the pistons run without pushing the model around.
    The knob on the left side is the gear shifter. The gearbox has only one gear to connect or disconnect the rear wheel to the engine.

    Again this will become a very tough race again, so stay tuned for more updates.
    However, being part of a EB contest is always an honor to me!

    The rain was gone this morning, so I made some photo's with my real Ducati :)

    WuPlZgW.jpg

    It's a 749 instead of a Panigale, but close enough imo :)

    @vliet I noticed the same thing with the axle/pin-connectors. I thought it was just general crap qualitycontrol on colours these days, but you actually got new ones? Maybe I should report mine as well then...

    Nice bike! And I also like the ABS model ...

    Remove the panels, swap some colors, and you got a Streetfighter V4 track racer. :wink:
    1280x720.jpg

    Here is my try for a Streetfighter in white

    42107_02.jpg

    Obviously I need another copy of the set to finish it and I still don't know exactly how to build the face. Maybe I will use the original one ...

    To Bad Lego missed the chance to add an additional axle hole to the bottom of the new shock.


  10. Okay, thanks to the previos posts I will finish this entry :devil:

    The following pictures look quite similar to the already shown but these are the final ones and will be also used in the entry topic.

    31.jpg

    32.jpg

    There are only some minor changes to the previous posted pics. Main difference is that I skipped the safety cage. It looked too crowded with the fully assembled bodywork, specially at the a pillars.

    More pics:

    Spoiler

    33.jpg

    34.jpg

    35.jpg

    I also measured to front and it was too wide, 16 studs instead of the allowed 15, so I had to rebuild it.

    39.jpg

    In front is the new one, compared to the old one in the back. I like the new one more while it contains more details and fit a bit better.

    For those who are interested in the evolution:

    Spoiler

    36.jpg37.jpg

    On top the old one with 16 studs, in the middle the concept build and on bottom the new one.

    38.jpg

     

    While I have an unexpected day of work I will try to rebuild the diffuser and then attach the final bodywork.


  11. Please excuse, but I have to start again with the word Wow:

    WOW! So many nice and motivating comments overwhelmed me. Thanks for that.

    @Rudivdk that's a nice comment :grin:, very motivating. Too bad my build is not inspired by a Viper, so I didn't nail the wanted look. Can you guess the real car I was inspired by?

    By the way, I still want to build your White Lightning - best looking plane and MOC ever - and I already have a reserved place in my living room, but I missed the instructions for free period. Can you PM me how to get it in an uncomplicated way?

    @Lakop (another legendary member!) The grey system bricks are only a placeholder to check the general look. I'm still not sure if I want to use them ... And the headlights ... they still give me headaches. I don't know how to implement them nor which parts to use. One week left!

    @Erik Leppen motivating comment from you! It feels as an honour to me!

    You're right, the black sticker is cheating!

    @Void_S real beast! :grin::wub:

    Thanks again for these nice comments! They keep me motivated to finish this build as an TC entry :classic:
