The balance of performance, sound, style, and price is very high. (well) Personally, I am satisfied with the Large variant. I've been reading about the performance of this bike since before it was released, but now that I've ridden it myself, it's much lighter and more comfortable to ride than the OEM bike. The sound is not too loud and it is not too tiring to ride. The sound is just right for me, but some people may find it a bit lacking. I don't like Round TypeRound, Megaphone and Long Type, so Short Oval Compact and Slim Silencer was my first choice. The Stainless Steel Type with no browning does not emphasize the exhaust system too much and it looks as if the exhaust system is installed from the beginning. If you don't like it, you can choose another type. I think that it is good to be able to think about the purchase after reading it before the purchase because it is introduced in the blog as well as the running test and the Bench test developed firmly. I think the price is reasonable and good for JAPANFull Exhaust System. The only thing I regret is that it does not come with a new Exhaust Gasket and the tools to install the Spring. By the way, if you have the tools, you can install it in about 15 minutes if you are used to it.

The 2024 model is now additionally compatible.
In the development of the full exhaust system for the 21-GROM, WR's usually does the bench test first, and then the riding test to confirm the length and the details. But this time, they have developed the exhaust by the method that they can find out the tube length from the data of driving test, and they can finish it by chassis dynamo.
Since the gear ratios of the 4th and 5th gears of the new Grom are far apart, the emphasis was placed on actual driving tests rather than bench tests.
As a result, the power feel is smooth from the low speed range and from the low RPM range in 4th and 5th gear.
In the high speed range, WR's tried to improve the characteristics by bench testing, and you will feel the feeling of the engine blowing up well from the practical use range to the high rpm.
In general, most of the exhausts for GROM have an integrated exhaust pipe.
This contributes to cost reduction in mass production, but WR'S has a separate exhaust with a spring joint to accentuate the sporty atmosphere.
In order to satisfy the customers, WR's has focused on the quality of the exhaust and not the cost.
The exhaust pipe has been tapered from the Φ25.4 to the Φ50 tailpipe, which contributes to a stress-free engine performance.
The exhaust pipe is a 2 piece structure with a spring joint connection to create a more sporty atmosphere.
While most silencers are round, WR'S uses a short oval silencer.
The slim and compact silencer also contributes to the weight balance of the vehicle.
The weight reduction of 25-33% is also achieved, which contributes to the ease of operation.
The "Short Oval Type" silencer has a sporty sound with a low sound, and the "SS-OVAL Type" silencer has a mild and gentle sound by utilizing the silencer capacity with a low sound.
This time, a new stainless steel shell specification is also adopted.
Stainless steel specification with excellent shine and texture.
And you can choose from the titanium specification of the beautiful baking color peculiar to titanium.
Short oval F-BLACK (stainless steel shell) specification has been added to the lineup.
