“SS-OVAL Full Exhaust” Presented by WR’S who Knows Everything about Middle Bikes

What is customizing ...?

Adjusting the brake lever to your favorite position is one of the fine customizing. By loosening one bolt and adjusting parts to your favorite position, you can feel the motorcycle closer than ever. WR'S is developing every day in the hope that there is a WR'S exhaust system on such a custom extension line.

The WR'S advantage is the brand that has continued to develop exhaust systems specializing in the middle bikes since its establishment. We will introduce the WR'S exhaust system that is thoroughly profiled the characteristics of STD motorcycles using actual riding test and the chassis dynamometer, and repeat bench tests based on that data, and thoroughly concentrate on development without compromising WR'S exhaust system.

1. "SS-OVAL SUS polish specification" to the popular full exhaust system for the CB250R is now added.

 

"SUS Polish Spec.", which is a new lineup of polished stainless steel pipe, has been released. High-quality material "SUS304 (#400)" is used for the stainless steel pipe, and by buffing the surface of the pipe, it is designed to enjoy the burned color peculiar to stainless steel. The surface of the pipe is not coated but made of SUS polish, so you can enjoy the change in the burned color and achieve a reasonable price.

You can enjoy how the polished stainless pipe changes its color due to exhaust heat.

2. The classic exhaust system for the YZF-R25 [2BK-RG43J] is this! Full coverage from low rev range to high rev range!

 

The new model is one horsepower lower than the old model in terms of catalog specifications. However, this is not because the power simply decreased, but because the camshaft (including its weight) inside the engine, the piston shape, and the combustion chamber shape were newly designed. WR'S has developed a new exhaust system to bring out the true potential of the new model, instead of diverting the old model's full exhaust system, and made it the exclusive design for the new model. As a result, the peak power of the new model was able to obtain power specs that exceeded the spec. of the old model and did not fall below STD in almost all revs.

3. WR'S exhaust system for the Ninja250 (18 years-) is very hot as well as slip-on silencer!

 

WR'S repeated bench tests and are developing a full exhaust system under the strong intention as a concept of development that "If it is a full exhaust system that does not show the performance equivalent to the slip-on silencer or the performance commensurate with the unit price of the product, we don't release it to the market".

Instead of building an exhaust system by following the STD exhaust system structure, they developed the pipe diameter and pipe length using the power graph as a hint. As a result, they got quite interesting data, so they boiled down to that database and developed an exhaust system for the new Ninja250.

As a result, a more powerful exhaust system that is completely different from the slip-on type was completed.

Proximity Noise Volume: 94dB
Acceleration Noise Volume: 79dB
Weight: 3.85kg *(STD: 6.35kg)

4. SS-OVAL full exhaust system for the new 2019 Z250 is also available.

 

WR'S repeated bench tests and are developing a full exhaust system under the strong intention as a concept of development that "If it is a full exhaust system that does not show the performance equivalent to the slip-on silencer or the performance commensurate with the unit price of the product, we don't release it to the market".

Instead of building an exhaust system by following the STD exhaust system structure, they developed the pipe diameter and pipe length using the power graph as a hint. As a result, they got quite interesting data, so they boiled down to that database and developed an exhaust system for the new Z250.

As a result, a more powerful exhaust system that is completely different from the slip-on type was completed.

5. The SS-OVAL series has been started from this one! "SS-OVAL SHORT LINE" for the CBR250RR

 

Since the advent of the CBR250RR, the exhaust system that tightens the aggressive styling of the CBR250RR further and has realized the high-performance is the beginning of the "SS-OVAL SHORT_LINE". The WR'S had already developed a slip-on and full exhaust system, but has newly developed it specializing in the ease of handling from the low and middle rev range. As a result, you can experience a linear and outstanding response in any mode.

The power and styling have been made into the exhaust system that can be said to be the completed version of the CBR250RR.

Proximity Noise Volume: 92dB
Acceleration Noise Volume: 81dB
Weight: 3.85kg (STD: 8.46kg)
