[Specification] Government Certification Proximity exhaust noise: 85dB Acceleration noise: 77dB Weight: 1.85kg (-2.9kg compared to standard)
The tapered short silencer is placed at the end of the tailpipe, which extends backward along the line of the step plate for a race like design. One-piece structure achieves a significant weight reduction (-60% compared to stock). The performance of this engine is superior to that of the standard engine in the mid to high RPM range.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
This time, it was installed on JC75. TSR official says JC75 is not compatible, but they just haven't inspected it since the type change, so it will come on without any problem.
The following is the experience of an amateur who rode NORMAL for one year. (No Reset, I haven't even messed with the intake yet)
Changes in handling due to weight reduction For better or worse, it's lightly Quick.
The mid-range launch and acceleration were so much better that I could feel it. If you open Axel with a NORMAL feeling, the RPM is about 1000-1500 higher.
Decrease of Torque by the goodness of escape Do you feel that the first gear is a little more manageable? What do you think? so it may be offset by the weight loss.
Is the fuel consumption deterioration caused by the exhaust system performance not so bad? If anything, the rider will have more fun and turn it so the fuel economy will be worse.
The sound is great. Idling is moderation. This is the sound of so-called TSR. I'm probably most comfortable around 3000-5000. The volume suddenly becomes Large-like around 6000.
The only way I can describe the sound quality is that it's in the middle range between bubba and bubba bubba. It's not a dry kind of popping sound like a papa. If it's over 7,000, it's like baaaah! That's what it's like.
You don't have to tell me. It doesn't make it any better, and it doesn't make as much torque as OEM. It's like less than race and more than street. The dexterity-poor Grom leans more towards Sports performance.
Regrettably, I want to get closer to Motard-style, so I might convert it to Up type.View Detail
