由于20-cbr250rr与以前的车型有完全不同的规格,如发动机功率,Wr's已经更新了20-cbr250rr的ss-oval short_line全排气管的管道长度。
ss-oval short_line全排气管与std全排气管不同,它具有 "向下和短 "的风格,以其独特的风格以及绰绰有余的性能,是以前的流行产品。
发动机的制动也减少了,在低速时重新打开油门也不会有生涩的感觉。
对于那些追求摩托车最佳性能的人来说,它是最佳选择。
音质方面,完成了重低音和狂野的音质,让人联想到赛车现场,但作为jmca认证的消声器,音量很清晰。
这款消声器的设计是为了给你提供最狂野的音质,没有任何后顾之忧。
20- cbr250rr的原厂消声器已经从两个催化剂改为一个催化剂,由于发动机的性能和特性与消声器有很大的不同,wr's开发了一个专门为该车设计的消声器。
新的滑套式消声器的设计,为发动机提供了最佳的动力增益。
该发动机在设计时考虑到了完整的排气系统。
最后,通过改用全排气管,进一步证明了发动机的潜力,并实现了动力的大幅提升。
我们一直在寻找两者的最佳组合,通过改变中心管的长度和消音器的结构,并调整音量和音质。
如前所述,2020- cbr250rr与以前的车型相比,有更高的压缩比0.6,以及更多的动力,这导致了更大的音量和声压,使严格的jmca认证测试更加困难。
"最好的 "规格和 "更好的 "规格,体积稍小的规格被准备用于测试。
在这次测试中,我们准备了 "最好的 "消声器和 "更好的 "消声器。
内部工作台测试的测量结果显示,峰值功率增加了2.2至2.4马力,并且从中段开始,功率明显增加,而不会低于库存。
这对250cc的发动机来说是一个很好的动力升级。

【音质温和,声音小】->建议使用圆形全排气管。
【低沉而动感的音质】→推荐使用ss-oval型全排气管。
【整体狂野的音质,重低音的声音】→推荐使用ss-oval短_线全排气。
我们的产品系列中有3种消音器,你可以选择适合你的口味。
Since the 20- CBR250RR has completely different specs from the previous model in terms of engine power, WR'S is newly designed for the 20- CBR250RR, including the silencer structure.
The SS-OVAL SHORT_LINE Full Exhaust is a "down and short" style full exhaust that is different from the stock full exhaust and is a popular product from the previous model because of its unique style as well as its more than enough performance.
The jerky engine braking at normal speed has been alleviated, and there is no jerky feeling when the accelerator is turned back at low speed.
From the start, CBR250RR will give you a smooth start and strong acceleration that will show off its performance to the fullest.
The sound quality is finished with a heavy bass and wild sound quality, reminiscent of the racing scene, but as a JMCA certified exhaust, the volume is clear.
This is an exhaust that you can enjoy the wild sound quality without worry.
The stock exhaust of 20- CBR250RR was changed from having 2 catalytic converters to having 1 catalytic converters, and since the performance and characteristics of the engine differ greatly with the exhaust, WR'S developed a special design exhaust.
During the development of the Slip-On, the upper limit of the power-up was repeatedly tested on the bench, and WR's felt that the limit of the power-up was "no more".
At that time, WR's couldn't decide whether this was the upper limit of the stock exhaust or the upper limit of this engine, so I tried to develop the full exhaust.
As it turns out, by changing to a full exhaust system, the potential of the vehicle was further demonstrated and a significant power increase was achieved.
The basic exhaust pipe is the same as WR'S 2017-2019 full exhaust, but the center pipe length and silencer structure were changed to find the best combination, and the volume and sound quality were adjusted to the final specification.
As mentioned earlier, the 2020- CBR250RR has a higher compression ratio (0.6) than the previous model as well as more power, which results in a very high sound volume and sound pressure, making the tough JMCA certification test more difficult. In this certification test, WR's prepared the "best" specification and the "better" specification with slightly lower volume.
As a result, both exhausts passed the "best" specification test without any loss of power.
In WR's bench test, the peak power was increased by 2.2 to 2.4 horsepower respectively, and the power was successfully increased from the mid range without dropping below the stock power.
It's a big power up for a 250cc engine.
All of the sound quality is finished with bass sound, especially "SS-OVAL SHORT_LINE" is finished with wild sound quality with heavy bass sound, but 2020- CBR250RR is louder than the previous model with low compression ratio.
Round type full exhaust is recommended for [Mild sound quality with bass sound].
SS-OVAL type full exhaust is recommended for [low and sporty sound quality].
[overall wild sound quality with heavy bass] -> SS-OVAL SHORT_LINE full exhaust is recommended.
There are 3 types of silencers available, so you can choose the one that suits you best.
