Good day everyone!
P/S: Shhh, actually I really regrets modifying my T135 T_T // I come to this info tad too late, there are actually a lot of wonder in our default T135, we should not take things for granted.
Appreciate what you already had, before it will gone forever! My advice is, if you really wanna modify your T135, just change the stock CDI to Rextor Adjustable CDI like the one sold by Traxxas, change the tire with the more reliable brands and always take care of your Engine Oil, COMPULSORY to change the EO for at least ONCE a month. Other things, keep to factory standard, and you should be more than happy. If you always use good EO for your T135, your bike would run like its always new! Condolence for myself, destroying my T135, spent like RM1.2k(USD 350), still cannot outmeter my bike, SIGH.......
Another advice for myself and the rest of the forum members, do not count your top speed, etc etc bla bla.. If you want your bike to go to blazing 180km/h++, buy a super bike instead. Appreciate your factory setting T135, appreciate all aspect of your default T135!(other than the factory standard tire and CDI maybe >.<"). Remember that speed kills! Ride safe everyone!!
Just wanna share this story with the rest of the forum members, so that we can REALLY REALLY appreciate our factory standard T135, [highlight=red]please scroll till the end of this thread[/highlight].

[highlight=red]Project Leader: Toshinori Kuromoto[/highlight]
"Proud" is the word that the T135 Project Leader, Mr.Toshinori Kuromoto uses. But to build a model that truly inspires pride of ownership demands new advances in technology and true innovation.
The T135 boasts neo technologies throughout the total package of the kind that truly make this model a proud flagship of the Yamaha brand. “I think of the T135 as an epoch-making model for Yamaha in everything from its great engine and chassis to the magnificent styling,” says Mr. Kuromoto. “Everyone on the development team gave it their all and the result is a model that we can proudly call ‘an embodiment of the Yamaha brand’.”
Of course, in order to be a machine that they could truly be proud of, it had to be one that moved their souls as engineers. The leadingedge engineers that made up this development team also continued to evaluate it as discerning riders at the same time in order to make sure it was a model that was truly satisfying to ride. In other words they looked at it not as a commercial object but as a motorcycle that they would want to ride as a user. And when the T135 was finished they were all satisfied with the job they had done.
[highlight=red]Test Rider: Kaoru Kamimura[/highlight]
The last test that all new Yamaha motorcycles have to pass is on the test course. The test riding department is one where highly experienced test riders give the prototypes tough evaluations. Until these riders give a prototype their "OK"the testing and reworking go on. "We consider ourselves to be the closest department to the customers," says Mr. Kaoru Kamimura, who was in charge of riding tests for the T135. "So we have to be a tough gate to pass. There are things we absolutely cannot compromise on."
Of the many different factors we test for in the riding tests, from stability and reliability to handling, one of area that Yamaha has traditionally placed special importance on is whether or not the machine is truly fun to ride. Of course this held true for the T135 too. Says Mr. Kamimura, "We made sure that the T135 was not only a motorcycle that was easy to ride and gave you a sense of security, but also that there was true enjoyment to the ride, that there was an exciting pleasure to it."
So what does this "fun" that Yamaha dedicates itself to actually consist of? Test rider Kamimura says, "The big prerequisite is that the machine has the kind of outstanding handling stability that makes it easy for anyone to enjoy riding with full assurance. Then you want it to also be the kind of handling that responds faithfully to the will of the rider. A motorcycle that responds the way you want it to is one that is a pleasure to ride," he concludes.
[highlight=red]Chassis Design: Toshimasa Miyabe[/highlight]
Traditionally, what we call "Yamaha Handling" is outstanding handling stability that makes it easy for anyone to enjoy riding with full assurance and also, the kind of handling that responds faithfully to the will of the rider. And, of course the T135 is part of this tradition. So the T135 had a lot to live up to in the area of chassis design and lot of effort went into building a chassis for this model that met Yamaha's high standards. The adoption of liquid cooling meant that the layout had to accommodate resulting components like the radiator, and this was a first for a Yamaha moped. What's more, it had to be done without compromising the "Yamaha Handling." That set the bar very high for Mr. Toshimasa Miyabe, chassis design project chief working on the T135.
"In order to build a frame that gets a high level of rigidity while accommodating all the various functions a frame must, the easiest thing is to make it broad-boned and rugged," says Mr. Miyabe. "But, if you are a Yamaha frame designer, you want to build the lightest, slimmest frame you can. Personally, I have a very strong inclination to make everything as light as possible."A light frame is one of the essential elements of a light-handling machine. That's why the passion for lightness is in the blood of every Yamaha engineer.
It was on the T135 project that Mr. Miyabe was given the position of Project Chief for the first time. There were a lot of important decisions for him to make, like the engine position and the shape of the frame. And there were some high hurdles to clear in areas like frame weight and production cost. There was also the tough final hurdle to be cleared on the test track. Things that seemed to work well in computer simulations were shot down by Kamimura and his test riders. In the early stages of the project that was especially true.
"Sometimes the demands from the test team seemed almost impossible to satisfy," recalls Miyabe. "But we never wanted to say something couldn't be done. It is tough demands that ignite the passion of a design engineer: to tackle problems that at first seem impossible."
[highlight=red]Product Planning: Shinichiro Nishimura[/highlight]
Mr. Shinichiro Nishimura of Product Planning describes the T135's "Performal Moped" concept. "This is a machine that will give you the feeling of a quality ride in everyday use. But at the same time, if you decide you really want to push it, it will respond with an excitingly sporty ride. This is what makes the T135 a completely new type of moped, like nothing before.
The rider is the main character in this drama and so it has to be a motorcycle that can move the rider's soul, a motorcycle that can bring true satisfaction. This is why the engineers and designers who build it must bring real passion to their work. And it was this kind of passion that drove the T135 development project.
The motorcycle development process begins in product planning. The job here is to decide on the product concept: what kind of product is going to be built for what kind of target user. Says Product Planning's Nishimura, "We used a lot of analysis and survey results to build the T135 concept." But, he emphasizes that, "Underlying it all was a strong determination to out do the competition. Among the things we wanted to beat the competitors at were functionality and fuel economy. And, more than anything, with the T135 we wanted to beat the competition in the area of Yamaha's traditional strength: the performance of the ride.
In the past Yamaha's strength was in the field of performance 2-stroke engines. In the moped category as well, Yamaha brought out models with spunky 2-stroke engines that won popularity in the marketplace. But, as the trend of the times shifted to 4-stroke engines, Yamaha turned its focus to producing practical models.
Still, one quality that has always been in the blood of Yamaha engineers is the pursuit of models that are truly fun to ride. This led to the desire to build a 4-stroke model with the same sprite and spunky ride of a 2-stroke. To do this, top priority had to be placed on getting a powerful 4-stroke engine.
[highlight=red]Engine Design: Tatsuya Matsuda[/highlight]
The power unit mounted on the T135 is a completely new liquid-cooled 4-stroke 135cc single-cylinder engine. It is the first liquid-cooled engine ever mounted on a Yamaha moped. Tatsuya Masuda, who headed the engine design project team says, "We wanted an engine that would run strongly at high rpm in the countryside and be easy to use in slower mid- to low-speed range riding in the city." He goes on to say, "We also wanted it to be an engine that ran quietly and was very reliable. And to do this we spent an especially large amount of time and energy working out that most important spec for determining the character of an engine: its bore x stroke." The T135 adopts a liquid cooling system and an array of state-of-the-art technologies like Yamaha's DiASil cylinder and forged piston. But it was this bore x stroke that consumed much of Masuda’s efforts. It was with this spec that he sought to give the engine a truly Yamaha character.
"If you get this basic spec right, you can do a lot of things later to fine-tune the engine," says Mr. Masuda. It was around October of last year after a series of road tests in Thailand that Masuda was finally convinced they had the right bore x stroke spec. Project Leader Kuromoto looks back on that time: "When I saw Masuda in the hotel lobby after those test were over, there were tears in his eyes. He had gone to Thailand with the motorcycle himself to see how close it was to the image he had been working toward and I guess he was really pleased. That's how difficult the task he had been given with the T135 engine was: to get both low- to mid-speed ease of use and good power at high speeds."
"I was confident that I had chosen the right spec," says Masuda, "but I guess I still had some doubts going into the tests, and it wasn't until the results were in that I was 100% sure we had the right basic engine to build on. ”Laughing, he went on to say, “It was such a relief that I just couldn't hold back the tears. Crying like that was something I didn’t even do when my first child was born."
[highlight=red]Exterior Design: Kiyotaka Uemura[/highlight]
One of the biggest deciding factors in whether or not a machine is really one that you want for your own is the exterior design. Mr. Kiyotaka Uemura of GK Dynamics who was in charge of exterior design says, “Basically, I went after the design that looked coolest to me.” He goes on to say, “I would say in more specific terms that it is a sporty design with an aggressive look. I tried some innovative things while also staying within the bounds of what a moped is. I wanted to express the excitement and tension of pushing it to the very edge of that definition.
Project Leader Kuromoto says with a laugh, Kiyo-san [Uemura] can be a stubborn man, once he decides a design is good it is hard to change his mind. Then he adds: "But that is probably what makes a professional designer. Kiyo-san had digested a lot of information about the preferences in the countries the T135 was being designed for, and after that he followed his own designer instincts. In the end, a good design is a universal thing that transcends national borders."
"It's not like I won't change anything no matter what. And the purpose is not to push my original design through, no matter what," says Uemura with a smile. "There are times when we have to change the design for functional reasons. But working on this project was especially easy because when I'd sit down to talk things out with the engineers we found we were all working in basically the same direction."
We often hear of function and design spoken of as conflicting factors in motorcycle design, but Uemura insists that is not necessarily the case. “In places where function takes precedence, it can still be an appealing element if it is well designed,” says Uemura. “I believe that if you are really attentive to the overall design and all the details, the design as a whole and the things I want to say through it will not be compromised if function is allowed to take priority over design in a few places.”
