Brembo caliper essentials

I was going to buy KOHKEN 18mm, but I chose this one because the hard anodized aluminum one was discontinued.

The thing is well made and just fit the OHLINS Fork.

Since it is made with high precision, I installed it by tapping it with a Hammer a little and press-fitting it.

It is better than I expected. View detail

Essentials for Full Exhaust System Replacement

Purchased to replace with Full Exhaust System.
Failure to replace the Exhaust System when it is replaced may result in waste leakage.

It has always been the case, but it often falls off when replacing Gasket,
It is easier to install if you apply a thin layer of silicon grease and stick it to the Engine side.
There is a way to lightly crush the Gasket circle to make it an oval and attach it, though,
I use Grease because it seems to be less efficient for disposal. View detail

Top Bridge Set

Fits: SUZUKI GSX1300R HAYABUSA

3/5

Requires considerable processing

[How is it used?
The product is good, the angle can be adjusted freely.
Was the one you received as per Image?
That is correct.
K-factory's products are always of high quality!
Was the installation difficult?
It was super difficult.
It cannot be used normally without considerable processing.

Specifically.
The OEM key cylinder is secured with an anti-removal Bolt and cannot be removed without using destructive methods. ItsQuantity:It took me 2 days to remove the 2pc Bolt. hang it, heat it with a heater fan, and blow on it for about 10 minutes to melt the screw lock agent. In some cases, if the bolt does not turn even after heating, the OEM Top Bridge is cut and removed without removing the OEM CableBracket. (like a spring) must be removed to attach it to the Top Bridge here.

There is also no hole to fix the Handlebar Switch.
I don't think this is possible. Without any holes, the Handlebar SwitchBox cannot be fixed. Turn. You need to measure the position by yourself and drill the hole with Drill. If the position of the hole is slightly off, that's the end of it. The preparation for this is the Large thing.

Lastly, I think the fact that it does not come with a bar end is a bit odd, don't you? I installed it by modifying DAYTONA's bar end for 14mm. It is not usable without past.

The above is almost impossible to install without PRO or considerable skill.
There are many tools to use and experience is required.
How was your experience with it?
Installation was difficult, but Position is easy.
[Included Parts:were they on?
Instruction Manual only but it is hard to understand.
[Was there anything that disappointed you?
No Handlebar Switch fixing holes
It took a lot of time to process.

Barrett silencer

2/5

It's a shame, because Parenthesis looks great.

[How is it used?

I switched my car to a Z900RS and the NORMAL sound was not bad, but
Purchased because the sound quality was a little different from my taste and I wanted to change the appearance and reduce the weight.

The following imprements were installed on a previous Z900 (unmarked)
Full titanium exhaust & SC1-RSilencer by SC-PROJECT
This is a very dry comparison with

Was the one you received as per Image?

Material:I found it surprisingly heavy for this Size in Titanium.
The slanted area on the opposite side of the exit has a rough surface like sharkskin.

Was the installation difficult?

When installing the inner baffle, use a ring to hold it down so that it does not wobble inside.
The system allows the user to enter the parts, but there are many similar parts, so it was difficult to know which parts to use.
I wish they would number the bags containing the Parts.

Silencer band is included, but you need to prepare your own bracket and bolts for fixing.
You need to be creative and inventive yourself.
I installed it in combination with K-fac's CLRExhaust pipe,
The bracket is Nankai Parts' Universal Bracket Length 225mmOffset 75mm (Part No. MSTL-225FR-75),
The silencer was fastened to the OEMLoading Hook by using the OEMSilencer Fixing Bolt.
Spring is the one that came with the CLRExhaust pipe.

However, the Silencer band is a little small in diameter and deformed when used as it is.
The bracket is then connected to the OHLINS Preload Adjuster.
Spacer of 3mm was put in because of interference.

How was your experience with it?

In combination with K-fac CLRExhaust pipe, even with inner baffle in place.
Considerable blast from Idling.
It might be more annoying than the SC-PROJECTFull Exhaust System without Baffle that was installed on my previous Z900 with the same Straight structure.

The Z900 series has a high ColdStart Idling.
Idling in a residential area is a Level that is sure to be Objection from neighbors.
Baffles can be attached to the exits as well,
It sounds like a whistle, like a Large Dump car, and I can't bring myself to use it.

The sound quality is rough and muddy from Idling with CLRExhaust pipe + Inner baffle.
The sound does not become a clear high-pitched or pleasant sound as it is turned, and it remains a harsh, dusky sound until the very end.
The trend may be similar to the OEM sound.

It seems that the inner baffle is causing a lot of exhaust resistance.
I don't feel that the low speed Torque is extremely gone and AfterFirea is not at all.
I feel that the performance has been downgraded quite clearly because it feels like it is jammed on top despite the bombast.

I tried running the next day WITHOUT Baffle's full Straight and it was so loud that I could say it was heinous.
Level, which is no different from the straight pipe of a family car.
The sound quality and running are better than with Baffle, but at any rate, it is too noisy.
It is highly likely that we will abandon the use of the system, although we need to consider whether we should compromise on driving and sound by emphasizing style.

Very disappointed because I like the look of Large.
Link pipe and Quantity as Slip-on Silencer for Z900RS OEM exhaust pipe:There are some that are sold Set.
It might work there.

[Included Parts:were they on?

・Instruction Manual
Silencer Band (possibly Material):(Stainless Steel)
Adapter for mounting on 54mm exhaust pipe, Spacer, etc.
1 pc. each of exit and inner baffle for installation.
K-fac Emblem
(Spring not included)

[Was there anything that disappointed you?

I was expecting the sound quality to be clear and pleasant like the previous SC-PROJECT car.
With Baffle, it was like a very loud OEM that I didn't like.
The sales pitch was that the volume could be adjusted by using a combination of inner and exit baffles.
The volume of the Inner is not as low as expected, and the sound quality is poor.
Exhaust resistance is too Large and performance is down from NORMAL to Large.

Invisible part

The Chromoly steel may be more durable than the OEM product. It is not that the durability of the OEM product is bad in the first place, it is just a self-fulfillment. It is not that the durability of the OEM product is bad in the first place. View detail

5/5

I like it.

Many users seem to use the OEM release of the ZZr1400, but I chose this one. I replaced the clutch master with this one right after purchasing the car, and I also replaced the clutch master at the same time, so I am not sure if the clutch lightening effect was effective or not, but I had enough time for a downhill touring of about 200km without any grip fatigue. However, when combined with brembo 17RCSMASTER, I feel that the stroke is a little insufficient, but there is no trouble such as difficulty in entering the GEAR. The installation is not particularly difficult as all you have to do is remove the OEM and replace it with the new one. View detail

2/5

Disappointed with the roughness of the finish.

[How is it used?

I switched my car to a Z900RS and the NORMAL sound was not bad, but
Purchased because the sound quality was a little different from my taste and I wanted to change the appearance and reduce the weight.

The following impressions are in comparison with the SC-PROJECT full titanium exhaust that was installed on the previous Z900 (unmarked).
So it is very dry.

Was the one you received as per Image?

The finish was worse than expected.
All of the pipes have scratches from the manufacturing process, and all of the exhaust pipes have weld marks.
It looks as if it is not a Pipe, but a plate material that has been rounded and welded.
The surface of the bending part is decorated with wrinkles.
Roughened surface like sharkskin can be seen throughout the entire surface (especially on Tail Pipe). (Tail Pipe is especially bad.)
Material:I also felt it was surprisingly heavy for Titanium.

The SC-PROJECT product was surprisingly light, with excellent finish and precision.
I assume the lightness is due to the use of thinner-walled Pipe than this product.
Naturally, the thinner the material, the higher the technology required for bending and welding.

Was the installation difficult?

The joint with the Tail Pipe also went in without any problem when combined with the same K-fac Bullet Silencer.
Aluminum's split flange seems easy to install, but in reality, it is not easy to install on the Stud.
It is difficult to do because of the "Rose" effect.
The installation of the assembly was easy, with no particular misalignment.
Clearance with the lower part of the Engine is quite low, making it difficult to set an extreme Pushing Up Style.
The Bracket that fixes the Wiring of the OEM's Lambda sensor was removed because it hit the assembly area.
The Lambda sensor mounting part is for the Z900RS, but for some reason, the position is on the opposite (back) side of the OEM.
It looks hard to do when removing it because it is about 10 cm away.

Since there are only two fixation points, one at the exhaust flange and the other at the silencer, it can be used for a long period of time.
Durability is a little uncertain.

How was your experience with it?

The thick exhaust pipe that looks like a hand bent, and the silencer angle of the pusher is also good for Parenthesis.
Material also gets a burnt color if it runs.:The good thing about TitaniumExhaust pipe.
The sound may depend on the Silencer combined, but since the catalyst and SaPig equalizer are eliminated, the sound is basically bombastic.
The sound quality is muddy from the Idling, with a rough, dusky sound rather than a clear, pleasant sound.
Exhaust pipes are just bundled together and not etc. length, which may cause turbidity due to exhaust interference, etc.
Frankly, I do not prefer it compared to the pleasant sound of SC-PROJECT.

Combined with Bullet Silencer but with Inner baffle
It seems that the exhaust resistance is quite low and I don't feel that the low speed Torque is extremely low, nor is the AfterFire at all.
It feels like the performance is down because it feels like it is stuck on top of the bomb.
I would like to eventually try it withwithout Baffle and other Silencer to see how the volume, sound quality, and performance changes.

If you think that you can get a Titanium Full Exhaust System at a relatively low price if you choose a cheap Silencer, you can get a Titanium Full Exhaust System at a relatively low price.
I would recommend it if you think it's cosmetic but don't care about the rest as long as it looks good.

[Included Parts:were they on?

Instruction Manual、Material:Includes AluminumFlange and Spring. (Also available for SilencerSpring)

[Was there anything that disappointed you?

As already mentioned, the roughness of the finish, weight, and sound quality are all disappointing.
Perhaps it was made by an apprentice? The finish makes you think
I must say that it is a bit disappointing to ship this Level in a product that costs more than 100,000.

According to the Instruction Manual, it is not returnable once the Vinyl containing the respective Parts is broken.
It is better to Check well before opening the package.

What does it mean that the initial four-month wait was suddenly delivered the following month?
Would it be too much to suspect that a B-grade shipment was made...
