[moto] Yamaha YZF-R7 Replace YZF-R6, This Is A Significant Difference Between The Two

[luminox™-]

Speaking of medium firing motorbikes under the Yamaha flag, the YZF-R6 is one that deserves a mention. Charisma R6 is inherent among motor sport lovers. Big body, and can also scream shrilly thanks to the four-cylinder engine. But all that ferociousness is only a memory, the production has been stopped.

After being present since 1999, Yamaha decided to stop production. As one of the flagship models, the R6 is quite respected. It is proven that during its 21-year cycle it received updates in 2001, 2003, 2006, 2008, and finally in 2017. Now its successor has been born in Europe, titled YZF-R7. What are the details of the differences?

 

Machine Changed Total
The format of the engine in the R7 generation is completely different from the Yamaha R6 it replaces. For the enthusiast of four piston engines must rub the chest. There will be no more strident screeching on the high spin. It could be that his breath is getting shorter. Because, what is being applied is the CP2 engine ammunition belonging to the Yamaha naked bike, MT-07.

Almost all of its components are precise. The R7 houses an air-cooled DOHC eight-valve inline two-cylinder engine. With a combination of diameter and measures 80 mm x 68.6 mm, it has a net berubikasi 689 cc. Until the compression density value is identical, 11.5: 1. Therefore, the output is in similar numbers, 72.3 Hp at 8,750 rpm and a maximum torque of 67 Nm coming out at 6,500 rpm.

When we compare it to the R6's, there is clearly a drop in horsepower coverage. This legendary engine output is capable of reaching 122 hp at 14,500 rpm. The pull is so long. Although indeed, the torque is smaller. But only a little, namely 65.7 Nm at 10,500 rpm. Naturally, the adoption of the 4-piston 599 cc DOHC 16 valve format must have a genuine sporting character. Not to mention the compression ratio density up to 13.1: 1.

Regarding this changing personality, it is possible to reap the pros and cons. In terms of power, people who like long runs may be disappointed. Regarding the sound, it can also be considered unpalatable. Because we know - when referring to MT-07 - the sound output tends to be hoarse and full. Not soft and crisp. However, this may be a middle ground for Yamaha, because the old engine did not pass Euro 5 regulations.

And the new CP2 machine, not necessarily lacking. In dimensions it is more compact. Likewise, compact weight, making the distribution of motor weight can be spread to other points. The issue of being more environmentally friendly is of course a reason. The following is claimed to be more relevant even though it is used daily. Make sense.

Their gearbox technology is also different. The R7 actually borrows an MT-07 with a six-speed configuration. It's just that there is already an assist and a slipper clutch, in order to secure the deceleration process from the risk of stomping the tires. And interestingly, there is an option to add a quick shifter, which is actually a racing motorbike. The system can work to raise gears without clutch only.

 

More Ergonomic Configuration
The R7 aluminum Deltabox frame also doesn't keep up with the R6's. The application is from the MT-07 platform, but several components are strengthened and optimized. For the sake of getting a rigid impression typical of motor sport. And for its own load, it's lighter than the old R6.

When compared in size, the total length of the R7 is more than 30 mm, the width is exactly, then the height is 65 mm above the R6. The wheelbase is also slightly longer. But it is a matter of overall dimensions measured at the end point. If it is claimed to be slimmer, the meaning may only feel clear in the legs, because the dimensions of the block and head are shrinking. And make it easier to maneuver. In addition, the seat height is lower for easier control.

What has changed is the driving position. While the R6 clearly offers the seat of a true super sport, the R7 is in the middle of the road. Your back muscles probably won't be in too much pain when riding this new species. Because it is not single focused on track needs. But it can be used daily, still comfortably. Although still leaning towards sports.

 

Slim Looking Body
In its form, it is not distinguished from the R series family. The inspiration of the R1 is quite evident in the new figure. Like the R6. One of the most interesting aspects is the vent in the middle of the facade. It seems like a real racing motorbike - especially when the main lights are turned off. The sink tub.

Even though that's where the main lighting source is, through a minimalist LED projector. Similar to the MT-Series. And when you pay attention to details, the intimidating impression is combined with the elegant side thanks to the sharp DRL on the left and right. The side and back areas also look streamlined, as well as have muscular lines. Still have a fierce look.

 

Specifications of the legs are not as good as the R6
Even though it is based on MT-07, regarding the provision of the R7 suspension, it is not actually used. If the naked bike uses a conventional fork and without settings, you can here. This KYB-made 41 mm upside down has compression and rebound settings. Likewise at the back, the monoshock can be adjusted according to the track that will be traversed.

It's just that, it doesn't make you proud if you see R6's. Upside down 41 mm really devoured the circuit. The type is fully adjustable, as is the rear monoshock. More varied arrangements. Not to mention, the diameter of the disc brake R6 is larger and looks solid in withstanding brutal force.

 

Price forecasts
Currently, the R6 is still on display on the official Yamaha Indonesia website. The selling value is called IDR 270 million OTR Jakarta. Interestingly, in Europe there the R7 sells for around Rp. 129 million. If it were true that they would enter Indonesia, the value could still be considered economical. At least not far from the MT-07 which was sold for Rp. 243 million OTR Jakarta. Although there is no definite information about this. (Pg / Raju)
