Yamaha R15M Test Ride: For Daily Use, Make Your Opponent 'Insecure'

 The All New Yamaha R15, the latest generation, was officially launched on December 2, 2021. Its presence has made the competition for entry-level full pharyngeal motorbikes even more heated. 

How not, he gets a number of changes, and the addition of new technology that makes his opponents 'insecure'.

As we all know, the new Yamaha R15 concoction is inspired by the R Series motorcycle. Racing DNA was passed down to him and packaged in the form of "The True Supersport 155cc Engine". The fascia is similar to the YZF-R7 and the fairing construction is identical to the YZF-R1 and M1. As a result, the body is denser and is claimed to be more aerodynamic.

It is offered in two types, the standard R15 Connected and the R15M Connected-ABS. This time we were given the opportunity to test the highest variant of the R15. Unlike the lower trim, the most expensive type we use is equipped with Traction Control System technology, Dual ABS, Quick Shifter (up), and Assist & Slipper Clutch. On the other hand, many are curious, are these features very useful when used for daily activities? For more details, here are the test ride results we got from the R15M from various aspects.

Riding Position Still the Same, But More 'Racy'

The first time sitting on it, the riding position is still the same as the previous model. The seat height is still 815mm. It's a little tiptoe, but not too much. Naturally, the height of the rider is only 173cm. When reaching for the handlebar type under york, the body is made slightly bent. Even so, the range is still tolerable.

At first it was a bit clumsy because I was looking for the location of the footstep. It turns out that the knee bends quite backwards. Understandably, riders usually carry scooters every day. The footpeg and handlebar positions are more or less similar, so the ergonomics triangle is no different from the previous generation R15. But specifically for the R15M type, there are nuances that make it more 'racy'. Because he uses the upper triangle whose shape is inspired by the YZR-M1. The center is holed horizontally and is given a blue front shock cover and a 3D emblem at the end of the tank. 

When driving, don't expect much about the comfort sector. However, the role of the seat helps a little to support the buttocks. Interestingly, this variant has been wrapped in leather with a carbon look pattern. In addition, the large tank cover that pops up is able to accommodate the stomach and chest when carried at high speed.

Visibility is also still quite good. Especially the front cowl, able to protect the rider from the wind in front. And this of course has an effect on performance, especially the top speed scores that can be achieved.

Thanks to the use of slip-on type handlebars, the cockpit feels spacious. Although the front is quite wide, the turning radius is quite a lot. When you want to turn back, you don't need more effort. Easy to control and lightweight.

And another interesting one. The yamaha R15M's speedometer is specially designed to look like the R1's. The digital screen has a larger dimension than before. In fact, it has 2 display options / modes, namely Street and Track. Mainly there is a new shift light which 5-point LED model lined up. Very motor racing style!

However, when used daily it is not very used because the eyes remain focused on the road. But it's different when used in circuits. You don't need to be afraid of getting into gear late, just the bright lyrics or the many points of the shift light are lit.

Stability Makes Confidence

Actually, there is no need to explain in detail about the stability of this R15M. Because the body structure is still the same as the previous model, still use the Deltabox frame. As we all know, the frame technology adopted is rigid and able to increase driving stability. And it was proven during the tests we did. Stability is maintained at both low and high speeds.

The use of an upside down suspension from KYB with a sport character is able to provide stability at high speeds. Moreover, it has been offset by monoshock rear shock absorbers with a sturdy and lightweight banana aluminum swing arm. Naturally, if he was ready to go down the track. For daily use is also not a problem. Devouring a variety of bends to be more steady. It's just that when passing a speed bump or on a bumpy road, the shock on the handlebars is quite pronounced, but still tolerable.

When taken for a leisurely stroll, this bike is quite stable and fun. Whereas for the 150cc class, the R15M has a weight of 140 kg. Because it is quite heavy, the effect at high speed does not feel floating. Besides, does this affect the succinctness of the maneuver? During the test, there were no problems when in the middle of a traffic jam. He still straightforwardly penetrates the narrow cavity between cars, motorbikes, and buses. It's just that you have to be able to predict when you are in the middle of a bigger vehicle. Because the mirrors used are quite wide. His agility is not much different from other Yamaha sport bikes. But because of the slightly bent riding position earlier, the rider gets tired quickly.

Good handling is also supported by the use of wide profile rims. 2.75-inch front with 17-inch rims wrapped in 110/80-17 tires. Rear 4 inches with the same diameter, wrapped in tires 140/70-17. Only if you want to feel good again, replace the tires that are a little wider. Yes, go up one step. Guaranteed, when taken cornering or when maneuvering, make the rider remain confident.

Genuine Motor Sport Performance

There is no doubt about the performance, although it is still the same as the previous model. According to Yamaha's 150 cc SOHC character, it excels in lower revs and acceleration. On paper, the pacemaker is capable of spitting out 19 hp at 10,000 rpm and 14.7 Nm of torque at 8,500 rpm. The compression ratio is 11.6:1, and the bore x stroke is 58 x 58.7 mm.

Testing impressions while on the road, in general there is no difference with the previous engine. When running at low engine speed, the graphics increase in power feels quite slow. This is useful for maintaining efficiency when driving in urban areas with stop and go conditions.

Breath each movement is also quite long. The power from the gas opening in each gear is responsive and can be felt at every engine speed. All that thanks to the variable valve cylinder head construction. As soon as you need maximum power, just twist the gas casing to 6,000 rpm, the original performance of the sport bike comes out right away. The valve adjusts immediately and is indicated by the appearance of the letter VVA above the tachometer. Power also throws more and acceleration feels faster.

While on a fairly quiet road, we tried to test speed. Yes, this motorbike is able to go up to a speed of 120 kph. Actually there's still some throttle opening left, but since this is a public road it's not good to go any further. This is just to conquer curiosity only. Overall the latest Yamaha R15 has a calm character but is ready to go wild if the rider wants it.

Guaranteed Safety Features

When we tried it, the embedded superior features were very useful. The first technology that we constantly feel is the presence of the assist and slipper clutch features. Very helpful when used for daily. It doesn't take more effort when operating the clutch lever, because it's light. Also useful when driving in traffic jams. While the slipper clutch is efficacious so that the rear wheels do not lock, even though lowering the gear when the engine is in high rotation.

Then Quick Shifter (up), making gearshifts smoother for city use. If in the circuit, of course, it can cut time during the process of shifting gears because there is no need to pull the clutch lever. But there is a little note for the manufacturer, at low speeds, the quick shifter which is already active at 2500 rpm still feels rough shifting gears. But if you have entered in high rotation, the work of this advanced feature is smoother.

Then it features a dual channel anti-lock brake system (ABS). In this test, we accidentally met a driver who immediately cut the lane. Immediately the rider makes a hard braking decision while at the same time balanced with an engine break, as a result, he can avoid danger. The motor lane can be controlled and the rear body does not move wildly. Oh yes, the R15M uses front calipers from Bybre (By Brembo). The response of the brake lever is softer with the bite force remaining calm but not surprising.

Not to forget the Traction Control System (TCS) which also contributes to a sense of security. It was proven when we passed the wet road after it rained. TCS performance is felt when there is a puddle of water around the corner. When you open the gas it turns out that the rear wheel almost slipped, that's where the feature works. Automatically reducing power, the engine immediately shuts down, so the rear tires can maintain traction. Almost!

Oh yes, besides there are features to ensure security and safety, there is one technology that we can't just forget. Yes, Y-Connect is also installed in this iron horse. Actually the contents of this system are similar to the Yamaha Maxi family (NMax and Aerox). Keep providing information about the condition of the motor. When connected, we can see news about recommendations for oil and battery maintenance, fuel consumption, the last parking location when connected to the application, malfunction notifications, phone and message notifications, dashboard revs to entertaining rank features. The difference is only at the beginning when opening the application. The silhouette of the R15 is displayed there. The rest are all the same.

During the test, we rarely monitored this technology, which is classified as a means of entertainment. Rider is too fun to be pampered with the superior features above. Only once in a while, and even then only see records of fuel consumption when arriving at their destination. The reason is because the placement of the instrument panel is at the end of the cockpit and behind the front fairing hood. It's a little hard to see when you're driving. However, the innovation provided by the manufacturer to the latest R15 deserves appreciation. Make it easy for all matters to care for your favorite motorbike. Cool!

Design

As we all know that the Yamaha R15M brings major changes in terms of design. Where the appearance of this 155cc sport bike is inspired by the MOGE R series.

The new look is most striking from the M-Shaped Intake Duct, which is an M-shaped air duct adopted from the YZR-M1 style. In that section there is one main lamp with an LED projector and there is also an addition with Twin Eyes DRL (Daytime Running Light) inspired by the YZF-R7.

The body panel design adopts two layers, supporting a sporty driving position typical of racing. Even the manufacturer claims this change makes the coefficient of aerodynamic analysis reduced from 0.307 to 0.293. Gives the advantage to reach top speed faster. 

The other side of the exterior also presents the aura of a big bike look. One of them is a full digital speedometer with a smart cockpit design concept inspired by the YZF-R1. In this highest type, the driver can set to change the display to Street and Track mode, as well as the presence of a time recorder or lap timer.

In addition, the use of seats with carbon motif covers makes the rider feel even more special. Other interesting things can also be seen from the presence of a 3D emblem symbol located at the end of the tank and blue fork caps bearing the R15M logo.

Problem color on the suspension is also fairly special. Given a yellow gold color for the front suspension tube and given a KYB sticker and yellow paint on the rear shock. The silver swing arm and exhaust cover also support a sporty look. While the tail is still the same as the previous model.

Conclusion

For daily use, of course, very qualified. Especially with a myriad of advanced features that have been pinned to it. All are very useful, in terms of entertainment, Y-connect is available, from the driving comfort side there is an assist & slipper clutch and quickshifter, to security and safety with two-channel ABS and TCS.

The four excellent features of course make opponents in their class 'insecure'. In the 150-155cc full fairing sport motorbike segment, only he has been equipped with technology equivalent to MOGE. All the embedded technologies at the same time answer the curiosity when the R15M is used daily. Safety is also guaranteed.

Meanwhile, for fuel efficiency, we have carried out a full-to-full test. He who has traveled a distance of 177 km spends 6,790 liters of fuel. That means 1 liter can cover a distance of about 26 km. This test is carried out only in cities with combined traffic. Stop and go when in traffic jams and drive several times at high speed when the road is empty. This figure of course can be different, depending on how to drive.
