As mentionned in my first post, it is this shifter, yes. I just take the principle because this design is not enough sturdy and reliable for a real use in a moc. I do modify it a little therefore, but Lego Technic Mastery is well the owner of the idea.

Sure! see below. I do not give up with the street bike. I just found this one was the most effective for a first bike with real sequential transmission.Thanks I am unfortunately not able to produce them. I can eventually produce ldd file. Yes, even if I do even not imagine ridding my H2 in socks, crazy guy! And thanks all for kind comments. Take 06 Time has come to finish the exterior design of this bike. @pagicence, Look at this:

I really like your loader! Original idea. Do you use or not a central differential? Minor point for me are the quiet visible medium motor in the rear design. Good job!

Sure ;)

I can't say what I most fan of. I love the multi use of a common plateform. superb job. So clean! I love your 3 ways tipper bed. No. I am really jalous of it ;) I like the overall clean design. pure technic spirit. I appreciate the motorized version wich is optional, so manual stuff that I like so much are well present and spot on. This model could seem 'gentle but for people who really now how hard the job behind is is, it is absolutely stunning. BTW, we both come to appreciate intermediary scales. At least it seems so. At this reduced scale I know how hard it can be and I give you friendly congrats therefore. Kudos for that all. Steph.

Sometime projects take a turn without you really realize it. During the work, as my main model was kept mounted and while I was working at MK17 on a second model this thing as born Take 05 This bike has a furious look. It has exactly the same dimensions as official TLG BMW 1200rs...and a sequential controlled 4 speeds gearbox. I had to change the colour scheme for a funny reason. My son just didn't accepted I took parts out off his Lamborghini and so I just came a little short in this lime colour. But Ok, back to this model. No particular mark or model for inspiration, but with it's 45 degrees V4 engine, this coul be a Honda Transalp, or some sort of KTM also. Other pictures: You can see here the work on the back fork. This articulation area include both sequential selector, gearbox commands shaft, fork articulation and driving chain. The bike has two exhausts, a confortable saddle and generous mudguards protections. Viewed from the driver's POV, this bike could be credibly comfortable. It is equipped with a large handlebar, and large travel suspension in the front and the rear Laterally, the profile is correspondent to this category bikes. The bike is equipped with a retractable crutch Underside view. It gives a good idea of the mechanical aspects. I am happy having be able to keep a width contained for this bike. And complete top view New orange selector. Still two days and I would not have one hair on my head anymore. detail of the exhausts realized out of Ninjago barels And at last, detail of the stepper and a last general view So whats the "hic" out there. This bike has suspensions, 4 speeds, 4 seeds commanded by foot stepper,4 seeds commanded by foot stepper and placed in the right order (MK 78452) So what's wrong? I just got two speeds in drive mode and...two reverses! Ok, I still have some work. Steph.

What to say ????? Maybe this: I really hope for TLG they didn't planed to introduce this model in the Porsche and Buggati lineup. I really don't see how in hell a model could be better. Great choice you've done by simplify the transmission in benefit of design and connex functionalities. PS: this model had rather be in the Scale Modeling section, no?

Sure, even if this gives me a stunning headache, need of some JB, and more. Take 04. Sometimes there are project that just do not want to go. Sometimes those project you got for years, haunt your nights until the day you decide time arrived. I always built bikes, and bikes with gearbox too. just look at this : http://www.brickshelf.com/cgi-bin/gallery.cgi?f=429878 we were in 1997. 21 years. Time's off. So back to the question @pagicence: the engine has been compacted a lot considering it now has a full drivetrain and gearbox linkages included. Design is also much cleaner than previously. This time the full transmission chain is done and work properly. I just hope my new parts arrive soon so I actually really need them to valid the gearbox concept. The whole setup of sequential stepper and linkage are also ok. As I explain previously I always work on several models together. The previous one has been evaluate in order to fix the mount points of the bodywork and for testing a new rear suspension arm. I still try to get back to mono-arm for the rear, but the pictures below will show you some scale markers to give you all a good idea of the direction of this project. Final view for today: no more engine in the upper part of the frame Steph.

take 03 - proof of spacing concept - not functional yet As some of you guys are asking themsemlf how in hell this all could get inside a bike....I do place the all things inside. So this question now is closed - the one only insignificant thing remaining is that it doesn't work actually. I still do not received the new orange elements and the pieces I ordered so it's difficult for me to go further on this project. So and instead of let it apart for a while I kept working on it. I concentrate my efforts on the sequential stepper's integration, and this part works properly actually. it's correctly placed, linked and connected to the gearbox. I now have the gearbox to solve. Second problem to solve : the back single arm for rear wheel. It is difficult to integrate it properly and his stability is just méh. I think i'll be back at regular double wishbone arm or mono-bloc arm - still to see. I finaly began to rebuild the gearbox's support frame introducting technic 5X7 frame in the structure to stabilize it. some pictures: This begin to look like a real hell machine no? Steph.

take 02 Maybe this compact stepper will help? Ps: credits to lego technic mastery for basic design, even if I improve it to reach high load use and rehabilitee standards. View near to the frame. the center verticals paddles are meant to fit in the center of the bike's frame. This lets enough place for a compact gearbox. Real problem is the linkage between elements. I only could check the setup once I get my parts from TLG. Other pictures to fit the scale: and last one: detail of the build: the mechanism has already a stop-point so the gearbox will pass the gear from 1 to 4 and never makes 4 to 1. Steph

Sure . This was the early fixation for engine and rear suspension. This will all completely be rebuilt once i would have done the engine and gearbox module. And you're right, it actually looks

Hi all, Here is my next project. First i would like to say that this is shot as a really early design stage. This is the first rush on that project. I do command from TLG the new orange selector for gearboxes. I do not received them actually. My first impression when seeing them for first time was that they were designed and intended to fit into a bike gearbox. That it was their reason of existing. And, as you always have better following your very first inspiration I do began the work on this project. Pictures! First, the main frame. As it do exist multiple sorts of frame I choose one who is the less conventional in a sense for a Lego model: This frame offer many advantages on a scale model, the main one is to free a maximum of space for the mechanics. Other view: The challenges are quiet hard on this project. As for many small MOCs the smaller they are, the most compact mechanics has to be and hardest is the designer's job. I am not a designer and even not engineer so i'll try do do my best to reach my goals with the best result I can. Here are my (hopefully) goals: - Superbike inspired - 4 speeds gearbox, with, if possible but I do not figure out on how, a neutral point correctly positioned between first and second speed. - Shifter commands like the real machines ... On design point of view, those bike are often fully careened . I do not think this will be the best choice for a technic model, as it would be great to have a full look at mecha inside. Here are the very first rushes on design: As you can see on the pictures below, there are still so much work to do.... For those who follow my workflow, you will understand my working method. I will now rebuild a second model independently of this one. I think I must begin by the engine part included gearbox setting and stepper commands. If you have any opinion idea or experience on this subject, feel free to post your stuffs and inspiration. Good sunny day all !

Thanks all! Another complementary thought omitted in the first post: I really enjoyed this exercise of modification. Starting from a healthy base (the official model) I was able to focus on one theme at a time. Each one constituting a mini project in the project. We start with the new chassis, integrating both the known attachment points of the body and imagining the spaces for the suite, it was the most difficult. Then each submodule is thought of as a proper entity: The selector, the BV .... then come the retouches, the trunk, the wheel arches. This allowed me to go step by step, without discouraging myself and concentrating on the essential with each time a significant analysis time but which is an integral part of the experience. Another thing omitted, the entire BV is made with the parts of old generation (driving rings in pair length) This forced me to be creative to avoid friction. So for example the changeover catch have all their own fixing points perfectly independent of the rotating axes of the gearbox. In the end the 99 euros invested have brought me infinitely more play time, fun shared with my son and the final satisfaction that the simple assembly of the set. Also, knowing during the initial editing that I was going to modify it, the editing time was used to understand the designer's ideas, to remove the essence, because it was these elements that were finally maintained and that forged the final success of the MOD. I am therefore looking forward to the next model of its kind, with great potential for change, because it is clear, it will not be the last;) Thanks again for your feedback

Thx. I've tried yesterday but wasn't convicted by bumpers replacement. However I do command them and I must receive my parts in 3-5 days Thanks Jim! it's so a little thing (red flex axles) that I do not understand TLG didn't go with them at first. it does :) And finally the very small mods of yesterday: - Continuous white line of the windshield profile until the trunk end, - B pillar - Getting back the driver seat by one stud with consequence of removing doors lock system. I finally found it was a good stuf but with one ugly aspect (springs) view from the inner of the car. On the other side I now have a credible space for driver's leg. I now wait for the parts I ordered, hoping they will be useful... NB: I also ordered 3 of those new orange gear selector..

Here we go. Take 04 Yesterday was time to mod the back of this car. Here is the result. Mail goal was to recreate a rear windshield , keep the spoiler and add some relive at the trunk here it is: And also keep main functionalities of these parts, it still open largely: You can see in picture below that I add two indicators on top of steering whell. Also, the trunck design match perfectly the gearbox command setup. It actually has a better access to the paddle shifter. The rear trunk links ave also been revised and it offer now a 3 position possible setup. From the mechanical point of view I rebuilt totally the gearbox stepper as it was only 80%reliable. After test, based on 100 gear changes up and down I am actually at 92% of success gear change. Can someone who own Porsche and/or Bugatti tell me if I am ok with those stats? Steph.

Thanks, I think this set is a really perfect start point for Mods. I am pleased that my work can give you some inspiration so you go further with your own model. Thanks. I find it gives some homogeneity to the side view and 3/4 front views of the car. This pictures was missing in my previous post: detail of the new seat: S.

What do you mean by this?

Take 3 Works goes on. Today one major update : functional and integrated shifter. I can say now I have a fully functional 4+N+R sequential gearbox I also take count of members opinions, idea and suggestions: I made new front grids and new seat General view : I really appreciate this model more and more. In the battle to integrate the gearbox shifter I had to get back to initial rear suspension setup. Rear view, I made some changes to the original design who was to flat and realy much too blue: the black parts in the centre of the hood are the shifter commands. After hours, in fact more than one day of work, I finaly get the idea to place the shifter at the back of the car. Much more practicable like this So what do you think about this guys? Steph EDIT: To @Horace T : picture of the new colored seat. I do not have the necessary parts in light or dark grey as there are two panels 1X5 to place.

Take 2. These two days work goes on. I placed the gearbox inside. Actually I have a smooth functional 4+N+R transmission. I still have to build and integrate a stepper or other mechanics to command the gearbox. I also work on the design errata. After trying to use the new wheel arches panel, which doesn't match on this model, I choose a simple flex axle in red that goes from the front to the rear in a continuous line. From mechanical point of views add a torsion bar for the rear suspension and I am actually working on a second one for the front axle witch is a little tricky. Here are more pictures of the actual state of the WIP: View of the complete car with full bodywork: View of the car with the bodywork removed. I love it like this. One of the next thing to do will be to simplify the bodywork connection to the frame so that it will be more easy to remove it: View of the anti-roll bar and gearbox commands: Detail of the upper part of the gearbox (simple 4 speed standard configuration) Interior view. I complete the design with a 5/11 panel in order of closing all the gaps in the frame. Interior looks credible like this. And finaly the pilot's space in a more detailed picture: As always any comments, idea or contribution is welcome. Steph.

It is. In this design, Chairs are used to stiffen the frame Yes, hé hé. I already tested it, but the wheels are ways ways to shorts for it....

When modding mine i have this picture in mind. (Renault Mégane) here Under next to my mod: Still some work to do but proportions are quiet ok. I also think that an standard Renault Yellow/Black livery could be cool. But first, the gearbox...

Thanks. Pleased to hear you like it both of you

Ok it seems i need some rest today

Thanks . Correction done

HI all, First of all, i still do not know if this project finaly is a Mod or a Moc. It all started when The Bugatti Chiron comes out and when i had to admit i just cannot pay so much money for it. I started thinking at what was attracting me in Bugatti and finaly comes to conclusion that it was simply the fact to have a complete technic package in one set. I began to think at building my own supercar. But as i can build about any Aéro MOC or helicopter you want, i also had to admit that building good designed car was not my cup of tea. So and after i read @Jim's 42077 review i decided to buy this set and i build it. My first impression was that i made the good choice, lots of free space in this (no so much) little set. After some hard thinking on how doing it, i realised i had to rebuilt the model from A to Z. So began the work to put some Chiron DNA in this rally car. The first thing i does was to rebuild the frame and structure of this car, taking care to keep the fixing point of bodywork at the right place. Re-building it also mean that this new car is now sturdy. Realy sturdy. All reinforcement have been re-thought and all ergonomy space Inside too. the seats are now proprely scaled, there is a functional driving Wheel... This is the actual state of the WIP: Ha ok, i forgot that: The V6 is out and let place to a 4 in line front transversal one, like on many real cars in real life I also re-thought all transmission. To be honest, the official set is a little poor at this point of view. So here comes the Chiron's DNA. First i place a D-N-R selector between the front seats As in the Chiron the reverse has is own shaff and the drive mode will be equiped with a gearbox. And the geear box will come here : at orginal set's engine place The selector of the sequential gearbox will use the original set's HOG emplacement, as the actual HOG is placed in the hole in the front hood At this point i had to solve the gearbox problem. From the design point of view i totaly review the suspensions setup to match the 'cup' spirit, i modify the position of the rear axle by one stud to the back, and add some flex axle to finish the rear design. I also solved two minors issues of the original set by adding a doors handle system (functionnal) and a rear view Mirror that lock the 'Billund high point' beam in position: Handles: Rear view Mirror lock: Any feedback is welcome Steph.
