Yamaha RX King 135cc Cafe Racer

Teguh Setiawan's Yamaha RX-K 135 1

OTOMOTIF.ORG - Well, for a start let me introduce myself. My name is Teguh Setiawan, I'm 24 y/o, I am an engineer college at one of the universities in Jogjakarta, Indonesia. In recent years, two-wheeled vehicles has evolved into a custom culture as often seen in the streets.

The occurrence began around 2012 when I several times saw the custom bikes on the streets, and attending a big event such as "Kustom Fest" that makes me started falling in love with a custom motorcycle especially Cafe Racer.

At the beginning of 2013 I bought my first Cafe Racer custom bike based on the Honda GL100 but I am not satisfied with the performance and the shape of the bike, then in March 2015, I bought a stock bike known as 2004 Yamaha RX K 135, commonly called the Yamaha RX King in my country (Indonesia).

This bike famous for its strong reputation and reliable machine, but because of government regulations on air emissions then this Oil-Burner-are already discontinue now. So lets call this project with “Long Live The King”.

The trick is to keep the quality high, even when the budget is not. And that's what I do on my second bike. I built this bike by myself from the beginning of the process and you should know that I do not have a custom garage or workshop and only armed with makeshift tools at my boarding house garage with the help of a few close friends for welding and painting processes.

This project takes a long time because of financial constraints, tools, and skills. But slowly it stakeholder concept become to reality for a “New Kids on the Block” like me. At least it took about 10 months to complete the project, although there are still some minor deficiencies in various angles.

I was only armed with a little knowledge from various sources such as magazines, videos on YouTube and watch the process of building custom bikes on my friends workshop. The process begins with finding the reference model of the Cafe Racer in several sources and I got the idea to build such a classic Yamaha TZ or Honda RC with full fairing. Then I started to make an initial concept and think of what needs to be done on this bike.

According to the design that I created on a drawing-card and cardboard,The first thing I did after unpacking the body is removing the engine and wiring then cutting off the rear sub-frame, leaving only the main frame. Then re-create the rear sub-frame with a 3/4 inch pipe of 2 mm thickness for get the perfect angle for riding position where before I’ve had made a square-shaped swing arm.

The difficult thing is to make a new gas tank because I did not have the expertise for it, then I look for a suitable tank in custom shop but still have not found a suitable one. Finally I chose to use an aftermarket tank, from classic Suzuki A100. I chose it because it has sleek shape and length enough. For the Engine, still with factory stock specification with only rebuilding and powder coated finishing my friend workshop.

A sheet of 0.8 mm galvanized plate is cut and shaped according to the fairing and hornet pattern that I made in cardboard. This is another challenge for me because of the shape that must be made to have perfect curve just by using makeshift tools like hammer and without English wheel. But finally done for that work with satisfying enough results.

The shopping list started with all the items that I need. A Rental tachometer fitted in front of custom upper triple T. The riding position was revised by fitting Ride It clip-on bars with simple control panels and a set of custom mounted rear-set foot pegs from Yoshimura.

I use original front and rear hub with polished Champ Rim fitted with Swallow S212 tire for both. Front brake and telescopic front fork are factory stock when rear brake switch to Nissin aftermarket disc brake and use Showa mono shock (later changed to confessional double shock for classic view reason).

All electricity put on below the gas tank when custom battery box hidden below custom seat with custom chrome battery cover. The special thing are this bike still leave rear seat with removable hornet for pillion passenger in emergency use. For remove the hornet easily by open the two bolt on it. For your information, that my bike is not only parked at my garage but also for daily use.

When it came time to paint the bike, the frame, swing arm, front fender and front fork painted with solid black and the body of solid blue with a mix of black on the fairing. When finished painting the body seems to be good if added Yamaha classic striping. After applying the finishing touches, lucky number 92 on both sides of the fairing according to the year of my birth, the whole lot given layer of a clear end.
