【AKRAPOVIC】Slip-on Exhaust (GP Type Silencer) Review

Power up required

The power band changes. But it has Torque feeling even at low rpm.
5 to 7 horsepower up. View detail

Normal muffler can rub with Full bank

Attached to R3. Although it was not dissatisfied with the sound and performance even in the state of NORMAL, there was a drawback that Silencer rubbed when doing a full bank.
The Exhaust System was optimal in terms of being inexpensive and not shaped to rub them.
Installation is simple. Gasket and Screw anti-burning agents are also included so they are kind. Some parts that require Torx wrench, so purchasing is necessary for those who do not have it.

As a characteristic, Torque slightly low rotation decreases, but it is not inconvenient in case of R3 where Torque is there so far. Blowing from 7000 rpm will be better. It was a feeling that it would rise like a clog in NORMAL, but it goes to Smooth even from 6 th speed 5000 rpm. Weight is also lighter by 2 kg so Right bank handling is lighter.

Sound does not become an explosive to that extent contrary to the appearance, high quality bass comes out. Since AfterFire A will also come out, people who care may need to take measures by exchanging with a thin Air Filter.
Since R25 and R3 are MainSilencer under the car body, it is unlikely that the sound will be very loud even if it is changed to Slip-on Silencer.

Of course, since it does not correspond to a car inspection etc., it is necessary to return to Normal muffler when passing the vehicle inspection. View detail

Although bass sounds slightly compared to OEM, it is not noisy about the volume. Also, I feel like the blowing up at low rotation became lighter.

The sound of After A Fire is also cool.

For the installation, I modified the Exhaust System for the first time, but it is easy with Slip-on Silencer. Tool is also OK with Wrench only.

I think that it is also recommended for those who want to customize Motorcycle for the first time. View detail

The AXIS La of motoGPStyle suits well for R25.

It is cheap and convenient for 250 cc Style - The volume can be changed
Slip-on Silencer is enough.
I can not hope for extreme PowerUP, but there is no PowerDOWN.
Bass is considerably increased compared to NORMAL.
Normal muffler is also noisy in the high revolution range
The change in the volume is not felt much.
Manufacturer published value says at 6,250 turns 93. Because it is 1 db
It might feel a bit noisy only in the city.
Worried persons should install Baffle of the Other Company Product.
Style is 250 cc but it's pretty good for SS 25 R 25
In Silencer, so-called motoGPStyle.
Even this alone would be worth buying. View detail

Great Exhaust. Great Look. Great Sound. The exhaust fit perfectly in my Yamaha YZF-R25. If I may suggest, it will be more convenient if the package supplied with specific screwdriver to tighten the metal clamp that use specific bolt. But overall I'm very

Great Exhaust. Great Look. Great Sound. The exhaust fit perfectly in my Yamaha YZF-R25.
