This is my reasons:
5. The bike design is evergreen and always fresh.
4. RX-Z is always related to power, speed, young and egoism.
3. RX-Z is not everyday bike to go to market buy fishes and vegetables. There is no ‘bakul’, man!
2. The sound of the bike can be modified to my liking whether it is loud and furious or just silent and purrs like a cat.
1. It is the only bike in its category that is available. Try to think for yourself, is there any other bike in this class?
What’s your reason?
1. Remove and clean the coversets. This is to make sure the parts are clean from oil and dirt.
1. Tanggalkan dan cuci coversets. Ini adalah untuk memastikan bahagian ini bersih daripada minyak dan kotoran.
2. Sand the parts with sand paper graded 800 mesh and above.
2. Gosok dengan kertas pasir dengan gred 800 mesh ke atas.
3. Spray the plastic parts with SAMURAI Plastic Primer to make sure the plastic parts can be neatly bonded with colour spray.
3. Sembur bahagian plastik dengan SAMURAI Plastic Primer untuk memastikan bahagian plastik ini dapat melekat dengan semburan warna dengan sempurna.
4. SAMURAI Putty Primer also sprayed to protect the plastic parts from scratches.
4. SAMURAI Putty Primer ini juga disembur untuk melindungi bahagian plastik ini daripada kesan-kesan calar.
5. Spray the SAMURAI Khameleon Undercoat.
5. Semburkan SAMURAI Khameleon Undercoat.
6. Use SAMURAI Hi-Temperature for the exhaust parts. SAMURAI Hi-Temperature can withstand temperature up to 600 degree Celcius.
6. Gunakan SAMURAI Hi-Temperature untuk bahagian ekzos. SAMURAI Hi-Temperature boleh menahan suhu sehingga 600 degree Celcius.
7. Spray SAMURAI Khameleon Spray Paint of your choice.
7. Semburkan warna SAMURAI Khameleon Spray Paint pilihan anda.
8. Spray SAMURAI 1K lacquer for multiple protection and maximum shine.
8. Semburkan SAMURAI 1K lacquer untuk perlindungan berganda dan kilauan yang maksima.

It seems that many chose 2-stroke as their favourite engine. This maybe due to 2-stroke have simpler design, lighter weight and more power.
Some also chose 4-stroke engine. Honda EX5, Yamaha Lagenda and Yamaha LC135 belong to this group of engine. 4-stroke produce less pollution and gives less noisy exhaust sound. One of my friend who owns LC135 tells me that he really loves the bike because he can cruise up to 140 km/h furiosly but still be almost silent.
There are two person who chose both engine as their favourite and only one person didn’t like engines. Hmm, I wonder why he/she visit this site then…
1. Use low-smoke 2T oil, like this one from Petronas; Petronas Sprinta 5000 2T 2-Stroke Full Synthetic.
2. Never mix different brand of 2T oil. For example, if you use Petronas Sprinta 5000, stick for it for the rest of the life of the bike. It is also okay if you stick with cheap 2T oil, as long as you don’t mix them up, you will get less smoke.
3. Adjust the 2T pump on your bike throttle cable. This will reduce the amount of the 2T that gets into the combustion, so you will get less smoke. Here you need to remember that when you reduce the amount of 2T oil that gets into your engine, you also minimise the lubricality of the engine. So, if you want to use your bike for heavy use (eg: racing), adjust the setting so that more 2T oil can be pumped to your engine.
4. Check, service and adjust your carburetor for maximum fuel and air mixture for combustion, as this one will make your combustion chamber cleaner and therefore produce less smoke.
5. Use your bike at optimum RPM. Your exhaust will form a resonance inside the exhaust chamber to produce back pressure and back pressure can give more fuel, air and 2T oil to be combusted back into the engine.
Any more idea? Share with us in the comments section.
Why do you need to use racing chamber exhaust?
The basic idea behind an expansion chamber is to use the momentum and pressure of the exhaust gases to create a pump that squeezes more air and fuel into the cylinder during the intake stroke. It does the same sort of thing that a turbocharger does, but it does it without moving parts.
If you have read How Two-stroke Engines Work, then you know that the exhaust and intake parts of the cycle overlap. As the piston moves down, it uncovers the exhaust port first to let most of the exhaust out. Then it opens the intake port to let fuel/oil/air in. With a correctly-tuned expansion chamber in place, two things happen to help the intake process:
- As the exhaust gases expand into the expansion chamber, they create a vacuum at the exhaust port. This vacuum pulls fuel/oil/air into the cylinder.
- As the shock wave of the exhaust pulse hits the end of the expansion chamber, it echoes back, pushing any fuel/oil/air that got pulled through the exhaust port back into the cylinder. This page has a nice graphic that describes the process.
By pulling extra fuel/oil/air through the cylinder and then pushing it back in, the expansion port has the effect of stuffing more fuel/oil/air into the cylinder on each stroke. This gives the engine extra power in the same way that a turbocharger does.

The poll have shown that Malaysian prefers Yamaha RX-Z more than 125Z, but LC135 is now the second choice after RX-Z. The least bike preferred is FZ-150i, this may due to the design of the bike that is not compelling and futuristic enough like the rest.
Keep voting for the new poll! Look for it at the right sidebar.
The current design of Yamaha 125ZR since 2007. The design of the bike is nice, simple and macho enough. It was debut in 1999 with the first generation of 125Z and later followed up with 125ZR, which better and meaner.
|Overall length x width x height
1,900 x 675 x 1,035 mm
|Minimum Ground Clearance
|Dry weight/ Curb weight
|Engine oil capacity
Digital-advanced magneto type CDI
Constant mesh 6-speed
|Brake front / rear
Single disc brake
At that time, there is no bike in the category that can compete with the bike. It was the era of Suzuki Best, Suzuki RG Sports, Yamaha SS, SS Two and Kawasaki K1, but none of the bike make a very deep impact like 125Z does. 125Z makes every other bike in the category seems like child plays. The technology offered by 125Z is far superior than what the people were thinking at that time and Yamaha was ahead in others in thinking of future of underbone bike.
I like this bike not because I want to rem pit, but I like what this bike has to offer.
You see, this is the only bike in the category that have monoshock suspension, front and rear disc brake, 6-speed gear, futuristic design and affordable!
Also, this bike is really fast. In standard condition, it can go up to 160km/h, tune the exhaust a bit, it’ll go up to 180km/h, tune it a little bit more, then you can’t measure the speed anymore since the meter is maxed at 180km/h!
I have heard that this bike can be tune to get 180 km/h just in the fourth gear.
Safety will become a thing to think here. Enjoy the speed only in the track. Not in public highway. Drive safely and be smart!
